It provides a simple, platform-independent API for +creating windows, contexts and surfaces, reading input, handling events, etc. + +GLFW natively supports Windows, macOS and Linux and other Unix-like systems. On +Linux both X11 and Wayland are supported. + +GLFW is licensed under the [zlib/libpng +license](https://www.glfw.org/license.html). + +You can [download](https://www.glfw.org/download.html) the latest stable release +as source or Windows binaries, or fetch the `latest` branch from GitHub. Each +release starting with 3.0 also has a corresponding [annotated +tag](https://github.com/glfw/glfw/releases) with source and binary archives. + +The [documentation](https://www.glfw.org/docs/latest/) is available online and is +included in all source and binary archives. See the [release +notes](https://www.glfw.org/docs/latest/news.html) for new features, caveats and +deprecations in the latest release. For more details see the [version +history](https://www.glfw.org/changelog.html). + +The `master` branch is the stable integration branch and _should_ always compile +and run on all supported platforms, although details of newly added features may +change until they have been included in a release. New features and many bug +fixes live in [other branches](https://github.com/glfw/glfw/branches/all) until +they are stable enough to merge. + +If you are new to GLFW, you may find the +[tutorial](https://www.glfw.org/docs/latest/quick.html) for GLFW 3 useful. If +you have used GLFW 2 in the past, there is a [transition +guide](https://www.glfw.org/docs/latest/moving.html) for moving to the GLFW +3 API. + +GLFW exists because of the contributions of [many people](CONTRIBUTORS.md) +around the world, whether by reporting bugs, providing community support, adding +features, reviewing or testing code, debugging, proofreading docs, suggesting +features or fixing bugs. + + +## Compiling GLFW + +GLFW itself requires only the headers and libraries for your OS and window +system. It does not need the headers for any context creation API (WGL, GLX, +EGL, NSGL, OSMesa) or rendering API (OpenGL, OpenGL ES, Vulkan) to enable +support for them. + +GLFW supports compilation on Windows with Visual C++ 2010 and later, MinGW and +MinGW-w64, on macOS with Clang and on Linux and other Unix-like systems with GCC +and Clang. It will likely compile in other environments as well, but this is +not regularly tested. + +There are [pre-compiled Windows binaries](https://www.glfw.org/download.html) +available for all supported compilers. + +See the [compilation guide](https://www.glfw.org/docs/latest/compile.html) for +more information about how to compile GLFW yourself. + + +## Using GLFW + +See the [documentation](https://www.glfw.org/docs/latest/) for tutorials, guides +and the API reference. + + +## Contributing to GLFW + +See the [contribution +guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for +more information. + + +## System requirements + +GLFW supports Windows XP and later and macOS 10.8 and later. Linux and other +Unix-like systems running the X Window System are supported even without +a desktop environment or modern extensions, although some features require +a running window or clipboard manager. The OSMesa backend requires Mesa 6.3. + +See the [compatibility guide](https://www.glfw.org/docs/latest/compat.html) +in the documentation for more information. + + +## Dependencies + +GLFW itself needs only CMake 3.1 or later and the headers and libraries for your +OS and window system. + +The examples and test programs depend on a number of tiny libraries. These are +located in the `deps/` directory. + + - [getopt\_port](https://github.com/kimgr/getopt_port/) for examples + with command-line options + - [TinyCThread](https://github.com/tinycthread/tinycthread) for threaded + examples + - [glad2](https://github.com/Dav1dde/glad) for loading OpenGL and Vulkan + functions + - [linmath.h](https://github.com/datenwolf/linmath.h) for linear algebra in + examples + - [Nuklear](https://github.com/Immediate-Mode-UI/Nuklear) for test and example UI + - [stb\_image\_write](https://github.com/nothings/stb) for writing images to disk + +The documentation is generated with [Doxygen](https://doxygen.org/) if CMake can +find that tool. + + +## Reporting bugs + +Bugs are reported to our [issue tracker](https://github.com/glfw/glfw/issues). +Please check the [contribution +guide](https://github.com/glfw/glfw/blob/master/docs/CONTRIBUTING.md) for +information on what to include when reporting a bug. + + +## Changelog + + -

Credits section +/// +/// ## About +/// This is a minimal state immediate mode graphical user interface toolkit +/// written in ANSI C and licensed under public domain. It was designed as a simple +/// embeddable user interface for application and does not have any dependencies, +/// a default renderbackend or OS window and input handling but instead provides a very modular +/// library approach by using simple input state for input and draw +/// commands describing primitive shapes as output. So instead of providing a +/// layered library that tries to abstract over a number of platform and +/// render backends it only focuses on the actual UI. +/// +/// ## Highlights +/// - Graphical user interface toolkit +/// - Single header library +/// - Written in C89 (a.k.a. ANSI C or ISO C90) +/// - Small codebase (~18kLOC) +/// - Focus on portability, efficiency and simplicity +/// - No dependencies (not even the standard library if not wanted) +/// - Fully skinnable and customizable +/// - Low memory footprint with total memory control if needed or wanted +/// - UTF-8 support +/// - No global or hidden state +/// - Customizable library modules (you can compile and use only what you need) +/// - Optional font baker and vertex buffer output +/// +/// ## Features +/// - Absolutely no platform dependent code +/// - Memory management control ranging from/to +/// - Ease of use by allocating everything from standard library +/// - Control every byte of memory inside the library +/// - Font handling control ranging from/to +/// - Use your own font implementation for everything +/// - Use this libraries internal font baking and handling API +/// - Drawing output control ranging from/to +/// - Simple shapes for more high level APIs which already have drawing capabilities +/// - Hardware accessible anti-aliased vertex buffer output +/// - Customizable colors and properties ranging from/to +/// - Simple changes to color by filling a simple color table +/// - Complete control with ability to use skinning to decorate widgets +/// - Bendable UI library with widget ranging from/to +/// - Basic widgets like buttons, checkboxes, slider, ... +/// - Advanced widget like abstract comboboxes, contextual menus,... +/// - Compile time configuration to only compile what you need +/// - Subset which can be used if you do not want to link or use the standard library +/// - Can be easily modified to only update on user input instead of frame updates +/// +/// ## Usage +/// This library is self contained in one single header file and can be used either +/// in header only mode or in implementation mode. The header only mode is used +/// by default when included and allows including this header in other headers +/// and does not contain the actual implementation.

+/// +/// The implementation mode requires to define the preprocessor macro +/// NK_IMPLEMENTATION in *one* .c/.cpp file before #includeing this file, e.g.: +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~C +/// #define NK_IMPLEMENTATION +/// #include "nuklear.h" +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// Also optionally define the symbols listed in the section "OPTIONAL DEFINES" +/// below in header and implementation mode if you want to use additional functionality +/// or need more control over the library. +/// +/// !!! WARNING +/// Every time nuklear is included define the same compiler flags. This very important not doing so could lead to compiler errors or even worse stack corruptions. +/// +/// ### Flags +/// Flag | Description +/// --------------------------------|------------------------------------------ +/// NK_PRIVATE | If defined declares all functions as static, so they can only be accessed inside the file that contains the implementation +/// NK_INCLUDE_FIXED_TYPES | If defined it will include header `` for fixed sized types otherwise nuklear tries to select the correct type. If that fails it will throw a compiler error and you have to select the correct types yourself. +/// NK_INCLUDE_DEFAULT_ALLOCATOR | If defined it will include header `` and provide additional functions to use this library without caring for memory allocation control and therefore ease memory management. +/// NK_INCLUDE_STANDARD_IO | If defined it will include header `` and provide additional functions depending on file loading. +/// NK_INCLUDE_STANDARD_VARARGS | If defined it will include header and provide additional functions depending on file loading. +/// NK_INCLUDE_VERTEX_BUFFER_OUTPUT | Defining this adds a vertex draw command list backend to this library, which allows you to convert queue commands into vertex draw commands. This is mainly if you need a hardware accessible format for OpenGL, DirectX, Vulkan, Metal,... +/// NK_INCLUDE_FONT_BAKING | Defining this adds `stb_truetype` and `stb_rect_pack` implementation to this library and provides font baking and rendering. If you already have font handling or do not want to use this font handler you don't have to define it. +/// NK_INCLUDE_DEFAULT_FONT | Defining this adds the default font: ProggyClean.ttf into this library which can be loaded into a font atlas and allows using this library without having a truetype font +/// NK_INCLUDE_COMMAND_USERDATA | Defining this adds a userdata pointer into each command. Can be useful for example if you want to provide custom shaders depending on the used widget. Can be combined with the style structures. +/// NK_BUTTON_TRIGGER_ON_RELEASE | Different platforms require button clicks occurring either on buttons being pressed (up to down) or released (down to up). By default this library will react on buttons being pressed, but if you define this it will only trigger if a button is released. +/// NK_ZERO_COMMAND_MEMORY | Defining this will zero out memory for each drawing command added to a drawing queue (inside nk_command_buffer_push). Zeroing command memory is very useful for fast checking (using memcmp) if command buffers are equal and avoid drawing frames when nothing on screen has changed since previous frame. +/// NK_UINT_DRAW_INDEX | Defining this will set the size of vertex index elements when using NK_VERTEX_BUFFER_OUTPUT to 32bit instead of the default of 16bit +/// NK_KEYSTATE_BASED_INPUT | Define this if your backend uses key state for each frame rather than key press/release events +/// +/// !!! WARNING +/// The following flags will pull in the standard C library: +/// - NK_INCLUDE_DEFAULT_ALLOCATOR +/// - NK_INCLUDE_STANDARD_IO +/// - NK_INCLUDE_STANDARD_VARARGS +/// +/// !!! WARNING +/// The following flags if defined need to be defined for both header and implementation: +/// - NK_INCLUDE_FIXED_TYPES +/// - NK_INCLUDE_DEFAULT_ALLOCATOR +/// - NK_INCLUDE_STANDARD_VARARGS +/// - NK_INCLUDE_VERTEX_BUFFER_OUTPUT +/// - NK_INCLUDE_FONT_BAKING +/// - NK_INCLUDE_DEFAULT_FONT +/// - NK_INCLUDE_STANDARD_VARARGS +/// - NK_INCLUDE_COMMAND_USERDATA +/// - NK_UINT_DRAW_INDEX +/// +/// ### Constants +/// Define | Description +/// --------------------------------|--------------------------------------- +/// NK_BUFFER_DEFAULT_INITIAL_SIZE | Initial buffer size allocated by all buffers while using the default allocator functions included by defining NK_INCLUDE_DEFAULT_ALLOCATOR. If you don't want to allocate the default 4k memory then redefine it. +/// NK_MAX_NUMBER_BUFFER | Maximum buffer size for the conversion buffer between float and string Under normal circumstances this should be more than sufficient. +/// NK_INPUT_MAX | Defines the max number of bytes which can be added as text input in one frame. Under normal circumstances this should be more than sufficient. +/// +/// !!! WARNING +/// The following constants if defined need to be defined for both header and implementation: +/// - NK_MAX_NUMBER_BUFFER +/// - NK_BUFFER_DEFAULT_INITIAL_SIZE +/// - NK_INPUT_MAX +/// +/// ### Dependencies +/// Function | Description +/// ------------|--------------------------------------------------------------- +/// NK_ASSERT | If you don't define this, nuklear will use with assert(). +/// NK_MEMSET | You can define this to 'memset' or your own memset implementation replacement. If not nuklear will use its own version. +/// NK_MEMCPY | You can define this to 'memcpy' or your own memcpy implementation replacement. If not nuklear will use its own version. +/// NK_SQRT | You can define this to 'sqrt' or your own sqrt implementation replacement. If not nuklear will use its own slow and not highly accurate version. +/// NK_SIN | You can define this to 'sinf' or your own sine implementation replacement. If not nuklear will use its own approximation implementation. +/// NK_COS | You can define this to 'cosf' or your own cosine implementation replacement. If not nuklear will use its own approximation implementation. +/// NK_STRTOD | You can define this to `strtod` or your own string to double conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!). +/// NK_DTOA | You can define this to `dtoa` or your own double to string conversion implementation replacement. If not defined nuklear will use its own imprecise and possibly unsafe version (does not handle nan or infinity!). +/// NK_VSNPRINTF| If you define `NK_INCLUDE_STANDARD_VARARGS` as well as `NK_INCLUDE_STANDARD_IO` and want to be safe define this to `vsnprintf` on compilers supporting later versions of C or C++. By default nuklear will check for your stdlib version in C as well as compiler version in C++. if `vsnprintf` is available it will define it to `vsnprintf` directly. If not defined and if you have older versions of C or C++ it will be defined to `vsprintf` which is unsafe. +/// +/// !!!

Calling any widgets outside these two functions will result in an +/// assert in debug or no state change in release mode.

+/// +/// Each window holds frame persistent state like position, size, flags, state tables, +/// and some garbage collected internal persistent widget state. Each window +/// is linked into a window stack list which determines the drawing and overlapping +/// order. The topmost window thereby is the currently active window.

+/// +/// To change window position inside the stack occurs either automatically by +/// user input by being clicked on or programmatically by calling `nk_window_focus`. +/// Windows by default are visible unless explicitly being defined with flag +/// `NK_WINDOW_HIDDEN`, the user clicked the close button on windows with flag +/// `NK_WINDOW_CLOSABLE` or if a window was explicitly hidden by calling +/// `nk_window_show`. To explicitly close and destroy a window call `nk_window_close`.

+/// +/// #### Usage +/// To create and keep a window you have to call one of the two `nk_begin_xxx` +/// functions to start window declarations and `nk_end` at the end. Furthermore it +/// is recommended to check the return value of `nk_begin_xxx` and only process +/// widgets inside the window if the value is not 0. Either way you have to call +/// `nk_end` at the end of window declarations. Furthermore, do not attempt to +/// nest `nk_begin_xxx` calls which will hopefully result in an assert or if not +/// in a segmentation fault. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // [... widgets ...] +/// } +/// nk_end(ctx); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// In the grand concept window and widget declarations need to occur after input +/// handling and before drawing to screen.

+/* ============================================================================= + * + * LAYOUT + * + * ============================================================================= +/// ### Layouting +/// Layouting in general describes placing widget inside a window with position and size. +/// While in this particular implementation there are five different APIs for layouting +/// each with different trade offs between control and ease of use.

+/// +/// All layouting methods in this library are based around the concept of a row. +/// A row has a height the window content grows by and a number of columns and each +/// layouting method specifies how each widget is placed inside the row. +/// After a row has been allocated by calling a layouting functions and then +/// filled with widgets will advance an internal pointer over the allocated row.

+/// +/// To actually define a layout you just call the appropriate layouting function +/// and each subsequent widget call will place the widget as specified. Important +/// here is that if you define more widgets then columns defined inside the layout +/// functions it will allocate the next row without you having to make another layouting

+/// call. +/// +/// Biggest limitation with using all these APIs outside the `nk_layout_space_xxx` API +/// is that you have to define the row height for each. However the row height +/// often depends on the height of the font.

+/// +/// To fix that internally nuklear uses a minimum row height that is set to the +/// height plus padding of currently active font and overwrites the row height +/// value if zero.

+/// +/// If you manually want to change the minimum row height then +/// use nk_layout_set_min_row_height, and use nk_layout_reset_min_row_height to +/// reset it back to be derived from font height.

+/// +/// Also if you change the font in nuklear it will automatically change the minimum +/// row height for you and. This means if you change the font but still want +/// a minimum row height smaller than the font you have to repush your value.

+/// +/// For actually more advanced UI I would even recommend using the `nk_layout_space_xxx` +/// layouting method in combination with a cassowary constraint solver (there are +/// some versions on github with permissive license model) to take over all control over widget +/// layouting yourself. However for quick and dirty layouting using all the other layouting +/// functions should be fine. +/// +/// #### Usage +/// 1. __nk_layout_row_dynamic__

+/// The easiest layouting function is `nk_layout_row_dynamic`. It provides each +/// widgets with same horizontal space inside the row and dynamically grows +/// if the owning window grows in width. So the number of columns dictates +/// the size of each widget dynamically by formula: +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// widget_width = (window_width - padding - spacing) * (1/colum_count) +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// Just like all other layouting APIs if you define more widget than columns this +/// library will allocate a new row and keep all layouting parameters previously +/// defined. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // first row with height: 30 composed of two widgets +/// nk_layout_row_dynamic(&ctx, 30, 2); +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // second row with same parameter as defined above +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // third row uses 0 for height which will use auto layouting +/// nk_layout_row_dynamic(&ctx, 0, 2); +/// nk_widget(...); +/// nk_widget(...); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// 2. __nk_layout_row_static__

+/// Another easy layouting function is `nk_layout_row_static`. It provides each +/// widget with same horizontal pixel width inside the row and does not grow +/// if the owning window scales smaller or bigger. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // first row with height: 30 composed of two widgets with width: 80 +/// nk_layout_row_static(&ctx, 30, 80, 2); +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // second row with same parameter as defined above +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // third row uses 0 for height which will use auto layouting +/// nk_layout_row_static(&ctx, 0, 80, 2); +/// nk_widget(...); +/// nk_widget(...); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// 3. __nk_layout_row_xxx__

+/// A little bit more advanced layouting API are functions `nk_layout_row_begin`, +/// `nk_layout_row_push` and `nk_layout_row_end`. They allow to directly +/// specify each column pixel or window ratio in a row. It supports either +/// directly setting per column pixel width or widget window ratio but not +/// both. Furthermore it is a immediate mode API so each value is directly +/// pushed before calling a widget. Therefore the layout is not automatically +/// repeating like the last two layouting functions. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // first row with height: 25 composed of two widgets with width 60 and 40 +/// nk_layout_row_begin(ctx, NK_STATIC, 25, 2); +/// nk_layout_row_push(ctx, 60); +/// nk_widget(...); +/// nk_layout_row_push(ctx, 40); +/// nk_widget(...); +/// nk_layout_row_end(ctx); +/// // +/// // second row with height: 25 composed of two widgets with window ratio 0.25 and 0.75 +/// nk_layout_row_begin(ctx, NK_DYNAMIC, 25, 2); +/// nk_layout_row_push(ctx, 0.25f); +/// nk_widget(...); +/// nk_layout_row_push(ctx, 0.75f); +/// nk_widget(...); +/// nk_layout_row_end(ctx); +/// // +/// // third row with auto generated height: composed of two widgets with window ratio 0.25 and 0.75 +/// nk_layout_row_begin(ctx, NK_DYNAMIC, 0, 2); +/// nk_layout_row_push(ctx, 0.25f); +/// nk_widget(...); +/// nk_layout_row_push(ctx, 0.75f); +/// nk_widget(...); +/// nk_layout_row_end(ctx); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// 4. __nk_layout_row__

+/// The array counterpart to API nk_layout_row_xxx is the single nk_layout_row +/// functions. Instead of pushing either pixel or window ratio for every widget +/// it allows to define it by array. The trade of for less control is that +/// `nk_layout_row` is automatically repeating. Otherwise the behavior is the +/// same. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // two rows with height: 30 composed of two widgets with width 60 and 40 +/// const float size[] = {60,40}; +/// nk_layout_row(ctx, NK_STATIC, 30, 2, ratio); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // two rows with height: 30 composed of two widgets with window ratio 0.25 and 0.75 +/// const float ratio[] = {0.25, 0.75}; +/// nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// // +/// // two rows with auto generated height composed of two widgets with window ratio 0.25 and 0.75 +/// const float ratio[] = {0.25, 0.75}; +/// nk_layout_row(ctx, NK_DYNAMIC, 30, 2, ratio); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// 5. __nk_layout_row_template_xxx__

+/// The most complex and second most flexible API is a simplified flexbox version without +/// line wrapping and weights for dynamic widgets. It is an immediate mode API but +/// unlike `nk_layout_row_xxx` it has auto repeat behavior and needs to be called +/// before calling the templated widgets. +/// The row template layout has three different per widget size specifier. The first +/// one is the `nk_layout_row_template_push_static` with fixed widget pixel width. +/// They do not grow if the row grows and will always stay the same. +/// The second size specifier is `nk_layout_row_template_push_variable` +/// which defines a minimum widget size but it also can grow if more space is available +/// not taken by other widgets. +/// Finally there are dynamic widgets with `nk_layout_row_template_push_dynamic` +/// which are completely flexible and unlike variable widgets can even shrink +/// to zero if not enough space is provided. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // two rows with height: 30 composed of three widgets +/// nk_layout_row_template_begin(ctx, 30); +/// nk_layout_row_template_push_dynamic(ctx); +/// nk_layout_row_template_push_variable(ctx, 80); +/// nk_layout_row_template_push_static(ctx, 80); +/// nk_layout_row_template_end(ctx); +/// // +/// // first row +/// nk_widget(...); // dynamic widget can go to zero if not enough space +/// nk_widget(...); // variable widget with min 80 pixel but can grow bigger if enough space +/// nk_widget(...); // static widget with fixed 80 pixel width +/// // +/// // second row same layout +/// nk_widget(...); +/// nk_widget(...); +/// nk_widget(...); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// 6. __nk_layout_space_xxx__

+/// Finally the most flexible API directly allows you to place widgets inside the +/// window. The space layout API is an immediate mode API which does not support +/// row auto repeat and directly sets position and size of a widget. Position +/// and size hereby can be either specified as ratio of allocated space or +/// allocated space local position and pixel size. Since this API is quite +/// powerful there are a number of utility functions to get the available space +/// and convert between local allocated space and screen space. +/// +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~c +/// if (nk_begin_xxx(...) { +/// // static row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered) +/// nk_layout_space_begin(ctx, NK_STATIC, 500, INT_MAX); +/// nk_layout_space_push(ctx, nk_rect(0,0,150,200)); +/// nk_widget(...); +/// nk_layout_space_push(ctx, nk_rect(200,200,100,200)); +/// nk_widget(...); +/// nk_layout_space_end(ctx); +/// // +/// // dynamic row with height: 500 (you can set column count to INT_MAX if you don't want to be bothered) +/// nk_layout_space_begin(ctx, NK_DYNAMIC, 500, INT_MAX); +/// nk_layout_space_push(ctx, nk_rect(0.5,0.5,0.1,0.1)); +/// nk_widget(...); +/// nk_layout_space_push(ctx, nk_rect(0.7,0.6,0.1,0.1)); +/// nk_widget(...); +/// } +/// nk_end(...); +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// +/// #### Reference +/// Function | Description +/// ----------------------------------------|------------------------------------ +/// nk_layout_set_min_row_height | Set the currently used minimum row height to a specified value +/// nk_layout_reset_min_row_height | Resets the currently used minimum row height to font height +/// nk_layout_widget_bounds | Calculates current width a static layout row can fit inside a window +/// nk_layout_ratio_from_pixel | Utility functions to calculate window ratio from pixel size +// +/// nk_layout_row_dynamic | Current layout is divided into n same sized growing columns +/// nk_layout_row_static | Current layout is divided into n same fixed sized columns +/// nk_layout_row_begin | Starts a new row with given height and number of columns +/// nk_layout_row_push | Pushes another column with given size or window ratio +/// nk_layout_row_end | Finished previously started row +/// nk_layout_row | Specifies row columns in array as either window ratio or size +// +/// nk_layout_row_template_begin | Begins the row template declaration +/// nk_layout_row_template_push_dynamic | Adds a dynamic column that dynamically grows and can go to zero if not enough space +/// nk_layout_row_template_push_variable | Adds a variable column that dynamically grows but does not shrink below specified pixel width +/// nk_layout_row_template_push_static | Adds a static column that does not grow and will always have the same size +/// nk_layout_row_template_end | Marks the end of the row template +// +/// nk_layout_space_begin | Begins a new layouting space that allows to specify each widgets position and size +/// nk_layout_space_push | Pushes position and size of the next widget in own coordinate space either as pixel or ratio +/// nk_layout_space_end | Marks the end of the layouting space +// +/// nk_layout_space_bounds | Callable after nk_layout_space_begin and returns total space allocated +/// nk_layout_space_to_screen | Converts vector from nk_layout_space coordinate space into screen space +/// nk_layout_space_to_local | Converts vector from screen space into nk_layout_space coordinates +/// nk_layout_space_rect_to_screen | Converts rectangle from nk_layout_space coordinate space into screen space +/// nk_layout_space_rect_to_local | Converts rectangle from screen space into nk_layout_space coordinates +*/ +/*/// #### nk_layout_set_min_row_height +/// Sets the currently used minimum row height. +/// !!!

+/// +/// Trees thereby can be nested for tree representations and multiple nested +/// collapsable UI sections.

Each starting functions takes a title label +/// and optionally an image to be displayed and the initial collapse state from +/// the nk_collapse_states section.

+/// +/// The runtime state of the tree is either stored outside the library by the caller +/// or inside which requires a unique ID. The unique ID can either be generated +/// automatically from `__FILE__` and `__LINE__` with function `nk_tree_push`, +/// by `__FILE__` and a user provided ID generated for example by loop index with +/// function `nk_tree_push_id` or completely provided from outside by user with +/// function `nk_tree_push_hashed`. +/// +/// #### Usage +/// To create a tree you have to call one of the seven `nk_tree_xxx_push_xxx` +/// functions to start a collapsable UI section and `nk_tree_xxx_pop` to mark the +/// end. +/// Each starting function will either return `false(0)` if the tree is collapsed +/// or hidden and therefore does not need to be filled with content or `true(1)` +/// if visible and required to be filled. +/// +/// !!!

+/* =============================================================== + * + * FONT + * + * ===============================================================*/ +/* Font handling in this library was designed to be quite customizable and lets + you decide what you want to use and what you want to provide. There are three + different ways to use the font atlas. The first two will use your font + handling scheme and only requires essential data to run nuklear. The next + slightly more advanced features is font handling with vertex buffer output. + Finally the most complex API wise is using nuklear's font baking API. + + 1.) Using your own implementation without vertex buffer output + -------------------------------------------------------------- + So first up the easiest way to do font handling is by just providing a + `nk_user_font` struct which only requires the height in pixel of the used + font and a callback to calculate the width of a string. This way of handling + fonts is best fitted for using the normal draw shape command API where you + do all the text drawing yourself and the library does not require any kind + of deeper knowledge about which font handling mechanism you use. + IMPORTANT: the `nk_user_font` pointer provided to nuklear has to persist + over the complete life time! I know this sucks but it is currently the only + way to switch between fonts. + + float your_text_width_calculation(nk_handle handle, float height, const char *text, int len) + { + your_font_type *type = handle.ptr; + float text_width = ...; + return text_width; + } + + struct nk_user_font font; + font.userdata.ptr = &your_font_class_or_struct; + font.height = your_font_height; + font.width = your_text_width_calculation; + + struct nk_context ctx; + nk_init_default(&ctx, &font); + + 2.) Using your own implementation with vertex buffer output + -------------------------------------------------------------- + While the first approach works fine if you don't want to use the optional + vertex buffer output it is not enough if you do. To get font handling working + for these cases you have to provide two additional parameters inside the + `nk_user_font`. First a texture atlas handle used to draw text as subimages + of a bigger font atlas texture and a callback to query a character's glyph + information (offset, size, ...). So it is still possible to provide your own + font and use the vertex buffer output. + + float your_text_width_calculation(nk_handle handle, float height, const char *text, int len) + { + your_font_type *type = handle.ptr; + float text_width = ...; + return text_width; + } + void query_your_font_glyph(nk_handle handle, float font_height, struct nk_user_font_glyph *glyph, nk_rune codepoint, nk_rune next_codepoint) + { + your_font_type *type = handle.ptr; + glyph.width = ...; + glyph.height = ...; + glyph.xadvance = ...; + glyph.uv[0].x = ...; + glyph.uv[0].y = ...; + glyph.uv[1].x = ...; + glyph.uv[1].y = ...; + glyph.offset.x = ...; + glyph.offset.y = ...; + } + + struct nk_user_font font; + font.userdata.ptr = &your_font_class_or_struct; + font.height = your_font_height; + font.width = your_text_width_calculation; + font.query = query_your_font_glyph; + font.texture.id = your_font_texture; + + struct nk_context ctx; + nk_init_default(&ctx, &font); + + 3.) Nuklear font baker + ------------------------------------ + The final approach if you do not have a font handling functionality or don't + want to use it in this library is by using the optional font baker. + The font baker APIs can be used to create a font plus font atlas texture + and can be used with or without the vertex buffer output. + + It still uses the `nk_user_font` struct and the two different approaches + previously stated still work. The font baker is not located inside + `nk_context` like all other systems since it can be understood as more of + an extension to nuklear and does not really depend on any `nk_context` state. + + Font baker need to be initialized first by one of the nk_font_atlas_init_xxx + functions. If you don't care about memory just call the default version + `nk_font_atlas_init_default` which will allocate all memory from the standard library. + If you want to control memory allocation but you don't care if the allocated + memory is temporary and therefore can be freed directly after the baking process + is over or permanent you can call `nk_font_atlas_init`. + + After successfully initializing the font baker you can add Truetype(.ttf) fonts from + different sources like memory or from file by calling one of the `nk_font_atlas_add_xxx`. + functions. Adding font will permanently store each font, font config and ttf memory block(!) + inside the font atlas and allows to reuse the font atlas. If you don't want to reuse + the font baker by for example adding additional fonts you can call + `nk_font_atlas_cleanup` after the baking process is over (after calling nk_font_atlas_end). + + As soon as you added all fonts you wanted you can now start the baking process + for every selected glyph to image by calling `nk_font_atlas_bake`. + The baking process returns image memory, width and height which can be used to + either create your own image object or upload it to any graphics library. + No matter which case you finally have to call `nk_font_atlas_end` which + will free all temporary memory including the font atlas image so make sure + you created our texture beforehand. `nk_font_atlas_end` requires a handle + to your font texture or object and optionally fills a `struct nk_draw_null_texture` + which can be used for the optional vertex output. If you don't want it just + set the argument to `NULL`. + + At this point you are done and if you don't want to reuse the font atlas you + can call `nk_font_atlas_cleanup` to free all truetype blobs and configuration + memory. Finally if you don't use the font atlas and any of it's fonts anymore + you need to call `nk_font_atlas_clear` to free all memory still being used. + + struct nk_font_atlas atlas; + nk_font_atlas_init_default(&atlas); + nk_font_atlas_begin(&atlas); + nk_font *font = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font.ttf", 13, 0); + nk_font *font2 = nk_font_atlas_add_from_file(&atlas, "Path/To/Your/TTF_Font2.ttf", 16, 0); + const void* img = nk_font_atlas_bake(&atlas, &img_width, &img_height, NK_FONT_ATLAS_RGBA32); + nk_font_atlas_end(&atlas, nk_handle_id(texture), 0); + + struct nk_context ctx; + nk_init_default(&ctx, &font->handle); + while (1) { + + } + nk_font_atlas_clear(&atlas); + + The font baker API is probably the most complex API inside this library and + I would suggest reading some of my examples `example/` to get a grip on how + to use the font atlas.

From now there will be an internal minimum +/// row height derived from font height. If you need a row smaller than +/// that you can directly set it by `nk_layout_set_min_row_height` and +/// reset the value back by calling `nk_layout_reset_min_row_height. +/// - 2017/06/08 (1.39.1) - Fixed property text edit handling bug caused by past `nk_widget` fix. +/// - 2017/06/08 (1.39.0) - Added function to retrieve window space without calling a `nk_layout_xxx` function. +/// - 2017/06/06 (1.38.5) - Fixed `nk_convert` return flag for command buffer. +/// - 2017/05/23 (1.38.4) - Fixed activation behavior for widgets partially clipped. +/// - 2017/05/10 (1.38.3) - Fixed wrong min window size mouse scaling over boundries. +/// - 2017/05/09 (1.38.2) - Fixed vertical scrollbar drawing with not enough space. +/// - 2017/05/09 (1.38.1) - Fixed scaler dragging behavior if window size hits minimum size. +/// - 2017/05/06 (1.38.0) - Added platform double-click support. +/// - 2017/04/20 (1.37.1) - Fixed key repeat found inside glfw demo backends. +/// - 2017/04/20 (1.37.0) - Extended properties with selection and clipboard support. +/// - 2017/04/20 (1.36.2) - Fixed #405 overlapping rows with zero padding and spacing. +/// - 2017/04/09 (1.36.1) - Fixed #403 with another widget float error. +/// - 2017/04/09 (1.36.0) - Added window `NK_WINDOW_NO_INPUT` and `NK_WINDOW_NOT_INTERACTIVE` flags. +/// - 2017/04/09 (1.35.3) - Fixed buffer heap corruption. +/// - 2017/03/25 (1.35.2) - Fixed popup overlapping for `NK_WINDOW_BACKGROUND` windows. +/// - 2017/03/25 (1.35.1) - Fixed windows closing behavior. +/// - 2017/03/18 (1.35.0) - Added horizontal scroll requested in #377. +/// - 2017/03/18 (1.34.3) - Fixed long window header titles. +/// - 2017/03/04 (1.34.2) - Fixed text edit filtering. +/// - 2017/03/04 (1.34.1) - Fixed group closable flag. +/// - 2017/02/25 (1.34.0) - Added custom draw command for better language binding support. +/// - 2017/01/24 (1.33.0) - Added programatic way of remove edit focus. +/// - 2017/01/24 (1.32.3) - Fixed wrong define for basic type definitions for windows. +/// - 2017/01/21 (1.32.2) - Fixed input capture from hidden or closed windows. +/// - 2017/01/21 (1.32.1) - Fixed slider behavior and drawing. +/// - 2017/01/13 (1.32.0) - Added flag to put scaler into the bottom left corner. +/// - 2017/01/13 (1.31.0) - Added additional row layouting method to combine both +/// dynamic and static widgets. +/// - 2016/12/31 (1.30.0) - Extended scrollbar offset from 16-bit to 32-bit. +/// - 2016/12/31 (1.29.2) - Fixed closing window bug of minimized windows. +/// - 2016/12/03 (1.29.1) - Fixed wrapped text with no seperator and C89 error. +/// - 2016/12/03 (1.29.0) - Changed text wrapping to process words not characters. +/// - 2016/11/22 (1.28.6) - Fixed window minimized closing bug. +/// - 2016/11/19 (1.28.5) - Fixed abstract combo box closing behavior. +/// - 2016/11/19 (1.28.4) - Fixed tooltip flickering. +/// - 2016/11/19 (1.28.3) - Fixed memory leak caused by popup repeated closing. +/// - 2016/11/18 (1.28.2) - Fixed memory leak caused by popup panel allocation. +/// - 2016/11/10 (1.28.1) - Fixed some warnings and C++ error. +/// - 2016/11/10 (1.28.0) - Added additional `nk_button` versions which allows to directly +/// pass in a style struct to change buttons visual. +/// - 2016/11/10 (1.27.0) - Added additional `nk_tree` versions to support external state +/// storage. Just like last the `nk_group` commit the main +/// advantage is that you optionally can minimize nuklears runtime +/// memory consumption or handle hash collisions. +/// - 2016/11/09 (1.26.0) - Added additional `nk_group` version to support external scrollbar +/// offset storage. Main advantage is that you can externalize +/// the memory management for the offset. It could also be helpful +/// if you have a hash collision in `nk_group_begin` but really +/// want the name. In addition I added `nk_list_view` which allows +/// to draw big lists inside a group without actually having to +/// commit the whole list to nuklear (issue #269). +/// - 2016/10/30 (1.25.1) - Fixed clipping rectangle bug inside `nk_draw_list`. +/// - 2016/10/29 (1.25.0) - Pulled `nk_panel` memory management into nuklear and out of +/// the hands of the user. From now on users don't have to care +/// about panels unless they care about some information. If you +/// still need the panel just call `nk_window_get_panel`. +/// - 2016/10/21 (1.24.0) - Changed widget border drawing to stroked rectangle from filled +/// rectangle for less overdraw and widget background transparency. +/// - 2016/10/18 (1.23.0) - Added `nk_edit_focus` for manually edit widget focus control. +/// - 2016/09/29 (1.22.7) - Fixed deduction of basic type in non `` compilation. +/// - 2016/09/29 (1.22.6) - Fixed edit widget UTF-8 text cursor drawing bug. +/// - 2016/09/28 (1.22.5) - Fixed edit widget UTF-8 text appending/inserting/removing. +/// - 2016/09/28 (1.22.4) - Fixed drawing bug inside edit widgets which offset all text +/// text in every edit widget if one of them is scrolled. +/// - 2016/09/28 (1.22.3) - Fixed small bug in edit widgets if not active. The wrong +/// text length is passed. It should have been in bytes but +/// was passed as glyphes. +/// - 2016/09/20 (1.22.2) - Fixed color button size calculation. +/// - 2016/09/20 (1.22.1) - Fixed some `nk_vsnprintf` behavior bugs and removed `` +/// again from `NK_INCLUDE_STANDARD_VARARGS`. +/// - 2016/09/18 (1.22.0) - C89 does not support vsnprintf only C99 and newer as well +/// as C++11 and newer. In addition to use vsnprintf you have +/// to include . So just defining `NK_INCLUDE_STD_VAR_ARGS` +/// is not enough. That behavior is now fixed. By default if +/// both varargs as well as stdio is selected I try to use +/// vsnprintf if not possible I will revert to vsprintf. If +/// varargs but not stdio was defined I will use my own function. +/// - 2016/09/15 (1.21.2) - Fixed panel `close` behavior for deeper panel levels. +/// - 2016/09/15 (1.21.1) - Fixed C++ errors and wrong argument to `nk_panel_get_xxxx`. +/// - 2016/09/13 (1.21.0) - !BREAKING! Fixed nonblocking popup behavior in menu, combo, +/// and contextual which prevented closing in y-direction if +/// popup did not reach max height. +/// In addition the height parameter was changed into vec2 +/// for width and height to have more control over the popup size. +/// - 2016/09/13 (1.20.3) - Cleaned up and extended type selection. +/// - 2016/09/13 (1.20.2) - Fixed slider behavior hopefully for the last time. This time +/// all calculation are correct so no more hackery. +/// - 2016/09/13 (1.20.1) - Internal change to divide window/panel flags into panel flags and types. +/// Suprisinly spend years in C and still happened to confuse types +/// with flags. Probably something to take note. +/// - 2016/09/08 (1.20.0) - Added additional helper function to make it easier to just +/// take the produced buffers from `nk_convert` and unplug the +/// iteration process from `nk_context`. So now you can +/// just use the vertex,element and command buffer + two pointer +/// inside the command buffer retrieved by calls `nk__draw_begin` +/// and `nk__draw_end` and macro `nk_draw_foreach_bounded`. +/// - 2016/09/08 (1.19.0) - Added additional asserts to make sure every `nk_xxx_begin` call +/// for windows, popups, combobox, menu and contextual is guarded by +/// `if` condition and does not produce false drawing output. +/// - 2016/09/08 (1.18.0) - Changed confusing name for `NK_SYMBOL_RECT_FILLED`, `NK_SYMBOL_RECT` +/// to hopefully easier to understand `NK_SYMBOL_RECT_FILLED` and +/// `NK_SYMBOL_RECT_OUTLINE`. +/// - 2016/09/08 (1.17.0) - Changed confusing name for `NK_SYMBOL_CIRLCE_FILLED`, `NK_SYMBOL_CIRCLE` +/// to hopefully easier to understand `NK_SYMBOL_CIRCLE_FILLED` and +/// `NK_SYMBOL_CIRCLE_OUTLINE`. +/// - 2016/09/08 (1.16.0) - Added additional checks to select correct types if `NK_INCLUDE_FIXED_TYPES` +/// is not defined by supporting the biggest compiler GCC, clang and MSVC. +/// - 2016/09/07 (1.15.3) - Fixed `NK_INCLUDE_COMMAND_USERDATA` define to not cause an error. +/// - 2016/09/04 (1.15.2) - Fixed wrong combobox height calculation. +/// - 2016/09/03 (1.15.1) - Fixed gaps inside combo boxes in OpenGL. +/// - 2016/09/02 (1.15.0) - Changed nuklear to not have any default vertex layout and +/// instead made it user provided. The range of types to convert +/// to is quite limited at the moment, but I would be more than +/// happy to accept PRs to add additional. +/// - 2016/08/30 (1.14.2) - Removed unused variables. +/// - 2016/08/30 (1.14.1) - Fixed C++ build errors. +/// - 2016/08/30 (1.14.0) - Removed mouse dragging from SDL demo since it does not work correctly. +/// - 2016/08/30 (1.13.4) - Tweaked some default styling variables. +/// - 2016/08/30 (1.13.3) - Hopefully fixed drawing bug in slider, in general I would +/// refrain from using slider with a big number of steps. +/// - 2016/08/30 (1.13.2) - Fixed close and minimize button which would fire even if the +/// window was in Read Only Mode. +/// - 2016/08/30 (1.13.1) - Fixed popup panel padding handling which was previously just +/// a hack for combo box and menu. +/// - 2016/08/30 (1.13.0) - Removed `NK_WINDOW_DYNAMIC` flag from public API since +/// it is bugged and causes issues in window selection. +/// - 2016/08/30 (1.12.0) - Removed scaler size. The size of the scaler is now +/// determined by the scrollbar size. +/// - 2016/08/30 (1.11.2) - Fixed some drawing bugs caused by changes from 1.11.0. +/// - 2016/08/30 (1.11.1) - Fixed overlapping minimized window selection. +/// - 2016/08/30 (1.11.0) - Removed some internal complexity and overly complex code +/// handling panel padding and panel border. +/// - 2016/08/29 (1.10.0) - Added additional height parameter to `nk_combobox_xxx`. +/// - 2016/08/29 (1.10.0) - Fixed drawing bug in dynamic popups. +/// - 2016/08/29 (1.10.0) - Added experimental mouse scrolling to popups, menus and comboboxes. +/// - 2016/08/26 (1.10.0) - Added window name string prepresentation to account for +/// hash collisions. Currently limited to `NK_WINDOW_MAX_NAME` +/// which in term can be redefined if not big enough. +/// - 2016/08/26 (1.10.0) - Added stacks for temporary style/UI changes in code. +/// - 2016/08/25 (1.10.0) - Changed `nk_input_is_key_pressed` and 'nk_input_is_key_released' +/// to account for key press and release happening in one frame. +/// - 2016/08/25 (1.10.0) - Added additional nk_edit flag to directly jump to the end on activate. +/// - 2016/08/17 (1.09.6) - Removed invalid check for value zero in `nk_propertyx`. +/// - 2016/08/16 (1.09.5) - Fixed ROM mode for deeper levels of popup windows parents. +/// - 2016/08/15 (1.09.4) - Editbox are now still active if enter was pressed with flag +/// `NK_EDIT_SIG_ENTER`. Main reasoning is to be able to keep +/// typing after commiting. +/// - 2016/08/15 (1.09.4) - Removed redundant code. +/// - 2016/08/15 (1.09.4) - Fixed negative numbers in `nk_strtoi` and remove unused variable. +/// - 2016/08/15 (1.09.3) - Fixed `NK_WINDOW_BACKGROUND` flag behavior to select a background +/// window only as selected by hovering and not by clicking. +/// - 2016/08/14 (1.09.2) - Fixed a bug in font atlas which caused wrong loading +/// of glyphes for font with multiple ranges. +/// - 2016/08/12 (1.09.1) - Added additional function to check if window is currently +/// hidden and therefore not visible. +/// - 2016/08/12 (1.09.1) - nk_window_is_closed now queries the correct flag `NK_WINDOW_CLOSED` +/// instead of the old flag `NK_WINDOW_HIDDEN`. +/// - 2016/08/09 (1.09.0) - Added additional double version to nk_property and changed +/// the underlying implementation to not cast to float and instead +/// work directly on the given values. +/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal +/// floating pointer number to string conversion for additional +/// precision. +/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal +/// string to floating point number conversion for additional +/// precision. +/// - 2016/08/08 (1.07.2) - Fixed compiling error without define `NK_INCLUDE_FIXED_TYPE`. +/// - 2016/08/08 (1.07.1) - Fixed possible floating point error inside `nk_widget` leading +/// to wrong wiget width calculation which results in widgets falsly +/// becomming tagged as not inside window and cannot be accessed. +/// - 2016/08/08 (1.07.0) - Nuklear now differentiates between hiding a window (NK_WINDOW_HIDDEN) and +/// closing a window (NK_WINDOW_CLOSED). A window can be hidden/shown +/// by using `nk_window_show` and closed by either clicking the close +/// icon in a window or by calling `nk_window_close`. Only closed +/// windows get removed at the end of the frame while hidden windows +/// remain. +/// - 2016/08/08 (1.06.0) - Added `nk_edit_string_zero_terminated` as a second option to +/// `nk_edit_string` which takes, edits and outputs a '\0' terminated string. +/// - 2016/08/08 (1.05.4) - Fixed scrollbar auto hiding behavior. +/// - 2016/08/08 (1.05.3) - Fixed wrong panel padding selection in `nk_layout_widget_space`. +/// - 2016/08/07 (1.05.2) - Fixed old bug in dynamic immediate mode layout API, calculating +/// wrong item spacing and panel width. +/// - 2016/08/07 (1.05.1) - Hopefully finally fixed combobox popup drawing bug. +/// - 2016/08/07 (1.05.0) - Split varargs away from `NK_INCLUDE_STANDARD_IO` into own +/// define `NK_INCLUDE_STANDARD_VARARGS` to allow more fine +/// grained controlled over library includes. +/// - 2016/08/06 (1.04.5) - Changed memset calls to `NK_MEMSET`. +/// - 2016/08/04 (1.04.4) - Fixed fast window scaling behavior. +/// - 2016/08/04 (1.04.3) - Fixed window scaling, movement bug which appears if you +/// move/scale a window and another window is behind it. +/// If you are fast enough then the window behind gets activated +/// and the operation is blocked. I now require activating +/// by hovering only if mouse is not pressed. +/// - 2016/08/04 (1.04.2) - Fixed changing fonts. +/// - 2016/08/03 (1.04.1) - Fixed `NK_WINDOW_BACKGROUND` behavior. +/// - 2016/08/03 (1.04.0) - Added color parameter to `nk_draw_image`. +/// - 2016/08/03 (1.04.0) - Added additional window padding style attributes for +/// sub windows (combo, menu, ...). +/// - 2016/08/03 (1.04.0) - Added functions to show/hide software cursor. +/// - 2016/08/03 (1.04.0) - Added `NK_WINDOW_BACKGROUND` flag to force a window +/// to be always in the background of the screen. +/// - 2016/08/03 (1.03.2) - Removed invalid assert macro for NK_RGB color picker. +/// - 2016/08/01 (1.03.1) - Added helper macros into header include guard. +/// - 2016/07/29 (1.03.0) - Moved the window/table pool into the header part to +/// simplify memory management by removing the need to +/// allocate the pool. +/// - 2016/07/29 (1.02.0) - Added auto scrollbar hiding window flag which if enabled +/// will hide the window scrollbar after NK_SCROLLBAR_HIDING_TIMEOUT +/// seconds without window interaction. To make it work +/// you have to also set a delta time inside the `nk_context`. +/// - 2016/07/25 (1.01.1) - Fixed small panel and panel border drawing bugs. +/// - 2016/07/15 (1.01.0) - Added software cursor to `nk_style` and `nk_context`. +/// - 2016/07/15 (1.01.0) - Added const correctness to `nk_buffer_push' data argument. +/// - 2016/07/15 (1.01.0) - Removed internal font baking API and simplified +/// font atlas memory management by converting pointer +/// arrays for fonts and font configurations to lists. +/// - 2016/07/15 (1.00.0) - Changed button API to use context dependend button +/// behavior instead of passing it for every function call. +/// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +/// ## Gallery +/// ![Figure [blue]: Feature overview with blue color styling](https://cloud.githubusercontent.com/assets/8057201/13538240/acd96876-e249-11e5-9547-5ac0b19667a0.png) +/// ![Figure [red]: Feature overview with red color styling](https://cloud.githubusercontent.com/assets/8057201/13538243/b04acd4c-e249-11e5-8fd2-ad7744a5b446.png) +/// ![Figure [widgets]: Widget overview](https://cloud.githubusercontent.com/assets/8057201/11282359/3325e3c6-8eff-11e5-86cb-cf02b0596087.png) +/// ![Figure [blackwhite]: Black and white](https://cloud.githubusercontent.com/assets/8057201/11033668/59ab5d04-86e5-11e5-8091-c56f16411565.png) +/// ![Figure [filexp]: File explorer](https://cloud.githubusercontent.com/assets/8057201/10718115/02a9ba08-7b6b-11e5-950f-adacdd637739.png) +/// ![Figure [opengl]: OpenGL Editor](https://cloud.githubusercontent.com/assets/8057201/12779619/2a20d72c-ca69-11e5-95fe-4edecf820d5c.png) +/// ![Figure [nodedit]: Node Editor](https://cloud.githubusercontent.com/assets/8057201/9976995/e81ac04a-5ef7-11e5-872b-acd54fbeee03.gif) +/// ![Figure [skinning]: Using skinning in Nuklear](https://cloud.githubusercontent.com/assets/8057201/15991632/76494854-30b8-11e6-9555-a69840d0d50b.png) +/// ![Figure [bf]: Heavy modified version](https://cloud.githubusercontent.com/assets/8057201/14902576/339926a8-0d9c-11e6-9fee-a8b73af04473.png) +/// +/// ## Credits +/// Developed by Micha Mettke and every direct or indirect github contributor.

use at your own risk + + Before #including, + + #define STB_IMAGE_WRITE_IMPLEMENTATION + + in the file that you want to have the implementation. + + Will probably not work correctly with strict-aliasing optimizations. + +ABOUT: + + This header file is a library for writing images to C stdio. It could be + adapted to write to memory or a general streaming interface; let me know. + + The PNG output is not optimal; it is 20-50% larger than the file + written by a decent optimizing implementation. This library is designed + for source code compactness and simplicity, not optimal image file size + or run-time performance. + +BUILDING: + + You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h. + You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace + malloc,realloc,free. + You can define STBIW_MEMMOVE() to replace memmove() + +USAGE: + + There are four functions, one for each image file format: + + int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); + int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); + int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); + int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); + + There are also four equivalent functions that use an arbitrary write function. You are + expected to open/close your file-equivalent before and after calling these: + + int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); + int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); + int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); + int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); + + where the callback is: + void stbi_write_func(void *context, void *data, int size); + + You can define STBI_WRITE_NO_STDIO to disable the file variant of these + functions, so the library will not use stdio.h at all. However, this will + also disable HDR writing, because it requires stdio for formatted output. + + Each function returns 0 on failure and non-0 on success. + + The functions create an image file defined by the parameters. The image + is a rectangle of pixels stored from left-to-right, top-to-bottom. + Each pixel contains 'comp' channels of data stored interleaved with 8-bits + per channel, in the following order: 1=Y, 2=YA, 3=RGB, 4=RGBA. (Y is + monochrome color.) The rectangle is 'w' pixels wide and 'h' pixels tall. + The *data pointer points to the first byte of the top-left-most pixel. + For PNG, "stride_in_bytes" is the distance in bytes from the first byte of + a row of pixels to the first byte of the next row of pixels. + + PNG creates output files with the same number of components as the input. + The BMP format expands Y to RGB in the file format and does not + output alpha. + + PNG supports writing rectangles of data even when the bytes storing rows of + data are not consecutive in memory (e.g. sub-rectangles of a larger image), + by supplying the stride between the beginning of adjacent rows. The other + formats do not. (Thus you cannot write a native-format BMP through the BMP + writer, both because it is in BGR order and because it may have padding + at the end of the line.) + + HDR expects linear float data. Since the format is always 32-bit rgb(e) + data, alpha (if provided) is discarded, and for monochrome data it is + replicated across all three channels. + + TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed + data, set the global variable 'stbi_write_tga_with_rle' to 0. + +CREDITS: + + PNG/BMP/TGA + Sean Barrett + HDR + Baldur Karlsson + TGA monochrome: + Jean-Sebastien Guay + misc enhancements: + Tim Kelsey + TGA RLE + Alan Hickman + initial file IO callback implementation + Emmanuel Julien + bugfixes: + github:Chribba + Guillaume Chereau + github:jry2 + github:romigrou + Sergio Gonzalez + Jonas Karlsson + Filip Wasil + Thatcher Ulrich + +LICENSE + +This software is dual-licensed to the public domain and under the following +license: you are granted a perpetual, irrevocable license to copy, modify, +publish, and distribute this file as you see fit. + +*/ + +#ifndef INCLUDE_STB_IMAGE_WRITE_H +#define INCLUDE_STB_IMAGE_WRITE_H + +#ifdef __cplusplus +extern "C" { +#endif + +#ifdef STB_IMAGE_WRITE_STATIC +#define STBIWDEF static +#else +#define STBIWDEF extern +extern int stbi_write_tga_with_rle; +#endif + +#ifndef STBI_WRITE_NO_STDIO +STBIWDEF int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); +STBIWDEF int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); +STBIWDEF int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); +STBIWDEF int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data); +#endif + +typedef void stbi_write_func(void *context, void *data, int size); + +STBIWDEF int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes); +STBIWDEF int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); +STBIWDEF int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data); +STBIWDEF int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data); + +#ifdef __cplusplus +} +#endif + +#endif//INCLUDE_STB_IMAGE_WRITE_H + +#ifdef STB_IMAGE_WRITE_IMPLEMENTATION + +#ifdef _WIN32 + #ifndef _CRT_SECURE_NO_WARNINGS + #define _CRT_SECURE_NO_WARNINGS + #endif + #ifndef _CRT_NONSTDC_NO_DEPRECATE + #define _CRT_NONSTDC_NO_DEPRECATE + #endif +#endif + +#ifndef STBI_WRITE_NO_STDIO +#include +#endif // STBI_WRITE_NO_STDIO + +#include +#include +#include +#include + +#if defined(STBIW_MALLOC) && defined(STBIW_FREE) && (defined(STBIW_REALLOC) || defined(STBIW_REALLOC_SIZED)) +// ok +#elif !defined(STBIW_MALLOC) && !defined(STBIW_FREE) && !defined(STBIW_REALLOC) && !defined(STBIW_REALLOC_SIZED) +// ok +#else +#error "Must define all or none of STBIW_MALLOC, STBIW_FREE, and STBIW_REALLOC (or STBIW_REALLOC_SIZED)." +#endif + +#ifndef STBIW_MALLOC +#define STBIW_MALLOC(sz) malloc(sz) +#define STBIW_REALLOC(p,newsz) realloc(p,newsz) +#define STBIW_FREE(p) free(p) +#endif + +#ifndef STBIW_REALLOC_SIZED +#define STBIW_REALLOC_SIZED(p,oldsz,newsz) STBIW_REALLOC(p,newsz) +#endif + + +#ifndef STBIW_MEMMOVE +#define STBIW_MEMMOVE(a,b,sz) memmove(a,b,sz) +#endif + + +#ifndef STBIW_ASSERT +#include +#define STBIW_ASSERT(x) assert(x) +#endif + +#define STBIW_UCHAR(x) (unsigned char) ((x) & 0xff) + +typedef struct +{ + stbi_write_func *func; + void *context; +} stbi__write_context; + +// initialize a callback-based context +static void stbi__start_write_callbacks(stbi__write_context *s, stbi_write_func *c, void *context) +{ + s->func = c; + s->context = context; +} + +#ifndef STBI_WRITE_NO_STDIO + +static void stbi__stdio_write(void *context, void *data, int size) +{ + fwrite(data,1,size,(FILE*) context); +} + +static int stbi__start_write_file(stbi__write_context *s, const char *filename) +{ + FILE *f = fopen(filename, "wb"); + stbi__start_write_callbacks(s, stbi__stdio_write, (void *) f); + return f != NULL; +} + +static void stbi__end_write_file(stbi__write_context *s) +{ + fclose((FILE *)s->context); +} + +#endif // !STBI_WRITE_NO_STDIO + +typedef unsigned int stbiw_uint32; +typedef int stb_image_write_test[sizeof(stbiw_uint32)==4 ?

under the [Stack +Overflow tag](https://stackoverflow.com/questions/tagged/glfw) or [Game +Development tag](https://gamedev.stackexchange.com/questions/tagged/glfw) on +Stack Exchange or in the IRC channel `#glfw` on +[Libera.Chat](https://libera.chat/). + +Questions about the design or implementation of GLFW or about future plans +should be asked in the [dev section](https://discourse.glfw.org/c/dev) of the +forum or in the IRC channel. Please don't open a GitHub issue to discuss design +questions without first checking with a maintainer. + + +## Reporting a bug + +If GLFW is behaving unexpectedly at run-time, start by setting an [error +callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling). +GLFW will often tell you the cause of an error via this callback. If it +doesn't, that might be a separate bug. + +If GLFW is crashing or triggering asserts, make sure that all your object +handles and other pointers are valid. + +For bugs where it makes sense, a short, self contained example is absolutely +invaluable. Just put it inline in the body text. Note that if the bug is +reproducible with one of the test programs that come with GLFW, just mention +that instead. + +__Don't worry about adding too much information__. Unimportant information can +be abbreviated or removed later, but missing information can stall bug fixing, +especially when your schedule doesn't align with that of the maintainer. + +__Please provide text as text, not as images__. This includes code, error +messages and any other text. Text in images cannot be found by other users +searching for the same problem and may have to be re-typed by maintainers when +debugging. + +You don't need to manually indent your code or other text to quote it with +GitHub Markdown; just surround it with triple backticks: + + ``` + Some quoted text. + ``` + +You can also add syntax highlighting by appending the common file extension: + + ```c + int five(void) + { + return 5; + } + ``` + +There are issue labels for both platforms and GPU manufacturers, so there is no +need to mention these in the subject line. If you do, it will be removed when +the issue is labeled. + +If your bug is already reported, please add any new information you have, or if +it already has everything, give it a :+1:. + + +### Reporting a compile or link bug + +__Note:__ GLFW needs many system APIs to do its job, which on some platforms +means linking to many system libraries. If you are using GLFW as a static +library, that means your application needs to link to these in addition to GLFW. + +__Note:__ Check the [Compiling +GLFW](https://www.glfw.org/docs/latest/compile.html) guide and or [Building +applications](https://www.glfw.org/docs/latest/build.html) guide for before +opening an issue of this kind. Most issues are caused by a missing package or +linker flag. + +Always include the __operating system name and version__ (e.g. `Windows +7 64-bit` or `Ubuntu 15.10`) and the __compiler name and version__ (e.g. `Visual +C++ 2015 Update 2`). If you are using an official release of GLFW, +include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the +__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. + +Please also include the __complete build log__ from your compiler and linker, +even if it's long. It can always be shortened later, if necessary. + + +#### Quick template + +``` +OS and version: +Compiler version: +Release or commit: +Build log: +``` + + +### Reporting a segfault or other crash bug + +Always include the __operating system name and version__ (e.g. `Windows +7 64-bit` or `Ubuntu 15.10`). If you are using an official release of GLFW, +include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the +__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. + +Please also include any __error messages__ provided to your application via the +[error +callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling) and +the __full call stack__ of the crash, or if the crash does not occur in debug +mode, mention that instead. + + +#### Quick template + +``` +OS and version: +Release or commit: +Error messages: +Call stack: +``` + + +### Reporting a context creation bug + +__Note:__ Windows ships with graphics drivers that do not support OpenGL. If +GLFW says that your machine lacks support for OpenGL, it very likely does. +Install drivers from the computer manufacturer or graphics card manufacturer +([Nvidia](https://www.geforce.com/drivers), +[AMD](https://www.amd.com/en/support), +[Intel](https://www-ssl.intel.com/content/www/us/en/support/detect.html)) to +fix this. + +__Note:__ AMD only supports OpenGL ES on Windows via EGL. See the +[GLFW\_CONTEXT\_CREATION\_API](https://www.glfw.org/docs/latest/window_guide.html#window_hints_ctx) +hint for how to select EGL. + +Please verify that context creation also fails with the `glfwinfo` tool before +reporting it as a bug. This tool is included in the GLFW source tree as +`tests/glfwinfo.c` and is built along with the library. It has switches for all +GLFW context and framebuffer hints. Run `glfwinfo -h` for a complete list. + +Always include the __operating system name and version__ (e.g. `Windows +7 64-bit` or `Ubuntu 15.10`). If you are using an official release of GLFW, +include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the +__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. + +If you are running your program in a virtual machine, please mention this and +include the __VM name and version__ (e.g. `VirtualBox 5.1`). + +Please also include the __GLFW version string__ (`3.2.0 X11 EGL clock_gettime +/dev/js`), as described +[here](https://www.glfw.org/docs/latest/intro.html#intro_version_string), the +__GPU model and driver version__ (e.g. `GeForce GTX660 with 352.79`), and the +__output of `glfwinfo`__ (with switches matching any hints you set in your +code) when reporting this kind of bug. If this tool doesn't run on the machine, +mention that instead. + + +#### Quick template + +``` +OS and version: +GPU and driver: +Release or commit: +Version string: +glfwinfo output: +``` + + +### Reporting a monitor or video mode bug + +__Note:__ On headless systems on some platforms, no monitors are reported. This +causes glfwGetPrimaryMonitor to return `NULL`, which not all applications are +prepared for. + +__Note:__ Some third-party tools report more video modes than are approved of +by the OS. For safety and compatibility, GLFW only reports video modes the OS +wants programs to use. This is not a bug. + +The `monitors` tool is included in the GLFW source tree as `tests/monitors.c` +and is built along with the library. It lists all information GLFW provides +about monitors it detects. + +Always include the __operating system name and version__ (e.g. `Windows +7 64-bit` or `Ubuntu 15.10`). If you are using an official release of GLFW, +include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the +__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. + +If you are running your program in a virtual machine, please mention this and +include the __VM name and version__ (e.g. `VirtualBox 5.1`). + +Please also include any __error messages__ provided to your application via the +[error +callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling) and +the __output of `monitors`__ when reporting this kind of bug.

This is not a bug. Set a [refresh +callback](https://www.glfw.org/docs/latest/window.html#window_refresh) if you +want to keep the window contents updated during a move or size operation. + +The `events` tool is included in the GLFW source tree as `tests/events.c` and is +built along with the library. It prints all information provided to every +callback supported by GLFW as events occur. Each event is listed with the time +and a unique number to make discussions about event logs easier. The tool has +command-line options for creating multiple windows and full screen windows. + +Always include the __operating system name and version__ (e.g. `Windows +7 64-bit` or `Ubuntu 15.10`). If you are using an official release of GLFW, +include the __GLFW release version__ (e.g. `3.1.2`), otherwise include the +__GLFW commit ID__ (e.g. `3795d78b14ef06008889cc422a1fb8d642597751`) from Git. + +If you are running your program in a virtual machine, please mention this and +include the __VM name and version__ (e.g. `VirtualBox 5.1`). + +Please also include any __error messages__ provided to your application via the +[error +callback](https://www.glfw.org/docs/latest/intro_guide.html#error_handling) and +if relevant, the __output of `events`__ when reporting this kind of bug.

For details on +a specific function in this category, see the @ref input. There are also guides +for the other areas of GLFW. + + - @ref intro_guide + - @ref window_guide + - @ref context_guide + - @ref vulkan_guide + - @ref monitor_guide + +GLFW provides many kinds of input. While some can only be polled, like time, or +only received via callbacks, like scrolling, many provide both callbacks and +polling. Callbacks are more work to use than polling but is less CPU intensive +and guarantees that you do not miss state changes. + +All input callbacks receive a window handle. By using the +[window user pointer](@ref window_userptr), you can access non-global structures +or objects from your callbacks. + +To get a better feel for how the various events callbacks behave, run the +`events` test program. It register every callback supported by GLFW and prints +out all arguments provided for every event, along with time and sequence +information. + + +@section events Event processing + +GLFW needs to poll the window system for events both to provide input to the +application and to prove to the window system that the application hasn't locked +up. Event processing is normally done each frame after +[buffer swapping](@ref buffer_swap). Even when you have no windows, event +polling needs to be done in order to receive monitor and joystick connection +events. + +There are three functions for processing pending events. @ref glfwPollEvents, +processes only those events that have already been received and then returns +immediately. + +@code +glfwPollEvents(); +@endcode + +This is the best choice when rendering continuously, like most games do. + +If you only need to update the contents of the window when you receive new +input, @ref glfwWaitEvents is a better choice. + +@code +glfwWaitEvents(); +@endcode + +It puts the thread to sleep until at least one event has been received and then +processes all received events. This saves a great deal of CPU cycles and is +useful for, for example, editing tools. + +If you want to wait for events but have UI elements or other tasks that need +periodic updates, @ref glfwWaitEventsTimeout lets you specify a timeout. + +@code +glfwWaitEventsTimeout(0.7); +@endcode + +It puts the thread to sleep until at least one event has been received, or until +the specified number of seconds have elapsed. It then processes any received +events. + +If the main thread is sleeping in @ref glfwWaitEvents, you can wake it from +another thread by posting an empty event to the event queue with @ref +glfwPostEmptyEvent. + +@code +glfwPostEmptyEvent(); +@endcode + +Do not assume that callbacks will _only_ be called in response to the above +functions. While it is necessary to process events in one or more of the ways +above, window systems that require GLFW to register callbacks of its own can +pass events to GLFW in response to many window system function calls. GLFW will +pass those events on to the application callbacks before returning. + +For example, on Windows the system function that @ref glfwSetWindowSize is +implemented with will send window size events directly to the event callback +that every window has and that GLFW implements for its windows. If you have set +a [window size callback](@ref window_size) GLFW will call it in turn with the +new size before everything returns back out of the @ref glfwSetWindowSize call. + + +@section input_keyboard Keyboard input + +GLFW divides keyboard input into two categories; key events and character +events. Key events relate to actual physical keyboard keys, whereas character +events relate to the Unicode code points generated by pressing some of them. + +Keys and characters do not map 1:1. A single key press may produce several +characters, and a single character may require several keys to produce. This +may not be the case on your machine, but your users are likely not all using the +same keyboard layout, input method or even operating system as you. + + +@subsection input_key Key input + +If you wish to be notified when a physical key is pressed or released or when it +repeats, set a key callback. + +@code +glfwSetKeyCallback(window, key_callback); +@endcode + +The callback function receives the [keyboard key](@ref keys), platform-specific +scancode, key action and [modifier bits](@ref mods). + +@code +void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods) +{ + if (key == GLFW_KEY_E && action == GLFW_PRESS) + activate_airship(); +} +@endcode + +The action is one of `GLFW_PRESS`, `GLFW_REPEAT` or `GLFW_RELEASE`. The key +will be `GLFW_KEY_UNKNOWN` if GLFW lacks a key token for it, for example +_E-mail_ and _Play_ keys. + +The scancode is unique for every key, regardless of whether it has a key token. +Scancodes are platform-specific but consistent over time, so keys will have +different scancodes depending on the platform but they are safe to save to disk. +You can query the scancode for any [named key](@ref keys) on the current +platform with @ref glfwGetKeyScancode. + +@code +const int scancode = glfwGetKeyScancode(GLFW_KEY_X); +set_key_mapping(scancode, swap_weapons); +@endcode + +The last reported state for every [named key](@ref keys) is also saved in +per-window state arrays that can be polled with @ref glfwGetKey. + +@code +int state = glfwGetKey(window, GLFW_KEY_E); +if (state == GLFW_PRESS) +{ + activate_airship(); +} +@endcode + +The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`. + +This function only returns cached key event state. It does not poll the +system for the current physical state of the key. + +@anchor GLFW_STICKY_KEYS +Whenever you poll state, you risk missing the state change you are looking for. +If a pressed key is released again before you poll its state, you will have +missed the key press. The recommended solution for this is to use a +key callback, but there is also the `GLFW_STICKY_KEYS` input mode. + +@code +glfwSetInputMode(window, GLFW_STICKY_KEYS, GLFW_TRUE); +@endcode + +When sticky keys mode is enabled, the pollable state of a key will remain +`GLFW_PRESS` until the state of that key is polled with @ref glfwGetKey. Once +it has been polled, if a key release event had been processed in the meantime, +the state will reset to `GLFW_RELEASE`, otherwise it will remain `GLFW_PRESS`. + +@anchor GLFW_LOCK_KEY_MODS +If you wish to know what the state of the Caps Lock and Num Lock keys was when +input events were generated, set the `GLFW_LOCK_KEY_MODS` input mode. + +@code +glfwSetInputMode(window, GLFW_LOCK_KEY_MODS, GLFW_TRUE); +@endcode + +When this input mode is enabled, any callback that receives +[modifier bits](@ref mods) will have the @ref GLFW_MOD_CAPS_LOCK bit set if Caps +Lock was on when the event occurred and the @ref GLFW_MOD_NUM_LOCK bit set if +Num Lock was on. + +The `GLFW_KEY_LAST` constant holds the highest value of any +[named key](@ref keys). + + +@subsection input_char Text input + +GLFW supports text input in the form of a stream of +[Unicode code points](https://en.wikipedia.org/wiki/Unicode), as produced by the +operating system text input system. Unlike key input, text input obeys keyboard +layouts and modifier keys and supports composing characters using +[dead keys](https://en.wikipedia.org/wiki/Dead_key). Once received, you can +encode the code points into UTF-8 or any other encoding you prefer. + +Because an `unsigned int` is 32 bits long on all platforms supported by GLFW, +you can treat the code point argument as native endian UTF-32. + +If you wish to offer regular text input, set a character callback. + +@code +glfwSetCharCallback(window, character_callback); +@endcode + +The callback function receives Unicode code points for key events that would +have led to regular text input and generally behaves as a standard text field on +that platform. + +@code +void character_callback(GLFWwindow* window, unsigned int codepoint) +{ +} +@endcode + + +@subsection input_key_name Key names + +If you wish to refer to keys by name, you can query the keyboard layout +dependent name of printable keys with @ref glfwGetKeyName. + +@code +const char* key_name = glfwGetKeyName(GLFW_KEY_W, 0); +show_tutorial_hint("Press %s to move forward", key_name); +@endcode + +This function can handle both [keys and scancodes](@ref input_key). If the +specified key is `GLFW_KEY_UNKNOWN` then the scancode is used, otherwise it is +ignored. This matches the behavior of the key callback, meaning the callback +arguments can always be passed unmodified to this function. + + +@section input_mouse Mouse input + +Mouse input comes in many forms, including mouse motion, button presses and +scrolling offsets. The cursor appearance can also be changed, either to +a custom image or a standard cursor shape from the system theme. + + +@subsection cursor_pos Cursor position + +If you wish to be notified when the cursor moves over the window, set a cursor +position callback. + +@code +glfwSetCursorPosCallback(window, cursor_position_callback); +@endcode + +The callback functions receives the cursor position, measured in screen +coordinates but relative to the top-left corner of the window content area. On +platforms that provide it, the full sub-pixel cursor position is passed on. + +@code +static void cursor_position_callback(GLFWwindow* window, double xpos, double ypos) +{ +} +@endcode + +The cursor position is also saved per-window and can be polled with @ref +glfwGetCursorPos. + +@code +double xpos, ypos; +glfwGetCursorPos(window, &xpos, &ypos); +@endcode + + +@subsection cursor_mode Cursor mode + +@anchor GLFW_CURSOR +The `GLFW_CURSOR` input mode provides several cursor modes for special forms of +mouse motion input. By default, the cursor mode is `GLFW_CURSOR_NORMAL`, +meaning the regular arrow cursor (or another cursor set with @ref glfwSetCursor) +is used and cursor motion is not limited. + +If you wish to implement mouse motion based camera controls or other input +schemes that require unlimited mouse movement, set the cursor mode to +`GLFW_CURSOR_DISABLED`. + +@code +glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED); +@endcode + +This will hide the cursor and lock it to the specified window. GLFW will then +take care of all the details of cursor re-centering and offset calculation and +providing the application with a virtual cursor position. This virtual position +is provided normally via both the cursor position callback and through polling. + +@note You should not implement your own version of this functionality using +other features of GLFW. It is not supported and will not work as robustly as +`GLFW_CURSOR_DISABLED`. + +If you only wish the cursor to become hidden when it is over a window but still +want it to behave normally, set the cursor mode to `GLFW_CURSOR_HIDDEN`. + +@code +glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_HIDDEN); +@endcode + +This mode puts no limit on the motion of the cursor. + +To exit out of either of these special modes, restore the `GLFW_CURSOR_NORMAL` +cursor mode. + +@code +glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_NORMAL); +@endcode + + +@anchor GLFW_RAW_MOUSE_MOTION +@subsection raw_mouse_motion Raw mouse motion + +When the cursor is disabled, raw (unscaled and unaccelerated) mouse motion can +be enabled if available. + +Raw mouse motion is closer to the actual motion of the mouse across a surface. +It is not affected by the scaling and acceleration applied to the motion of the +desktop cursor. That processing is suitable for a cursor while raw motion is +better for controlling for example a 3D camera. Because of this, raw mouse +motion is only provided when the cursor is disabled. + +Call @ref glfwRawMouseMotionSupported to check if the current machine provides +raw motion and set the `GLFW_RAW_MOUSE_MOTION` input mode to enable it. It is +disabled by default. + +@code +if (glfwRawMouseMotionSupported()) + glfwSetInputMode(window, GLFW_RAW_MOUSE_MOTION, GLFW_TRUE); +@endcode + +If supported, raw mouse motion can be enabled or disabled per-window and at any +time but it will only be provided when the cursor is disabled. + + +@subsection cursor_object Cursor objects + +GLFW supports creating both custom and system theme cursor images, encapsulated +as @ref GLFWcursor objects. They are created with @ref glfwCreateCursor or @ref +glfwCreateStandardCursor and destroyed with @ref glfwDestroyCursor, or @ref +glfwTerminate, if any remain. + + +@subsubsection cursor_custom Custom cursor creation + +A custom cursor is created with @ref glfwCreateCursor, which returns a handle to +the created cursor object. For example, this creates a 16x16 white square +cursor with the hot-spot in the upper-left corner: + +@code +unsigned char pixels[16 * 16 * 4]; +memset(pixels, 0xff, sizeof(pixels)); + +GLFWimage image; +image.width = 16; +image.height = 16; +image.pixels = pixels; + +GLFWcursor* cursor = glfwCreateCursor(&image, 0, 0); +@endcode + +If cursor creation fails, `NULL` will be returned, so it is necessary to check +the return value. + +The image data is 32-bit, little-endian, non-premultiplied RGBA, i.e. eight bits +per channel with the red channel first. The pixels are arranged canonically as +sequential rows, starting from the top-left corner. + + +@subsubsection cursor_standard Standard cursor creation + +A cursor with a [standard shape](@ref shapes) from the current system cursor +theme can be can be created with @ref glfwCreateStandardCursor. + +@code +GLFWcursor* url_cursor = glfwCreateStandardCursor(GLFW_POINTING_HAND_CURSOR); +@endcode + +These cursor objects behave in the exact same way as those created with @ref +glfwCreateCursor except that the system cursor theme provides the actual image. + +A few of these shapes are not available everywhere. If a shape is unavailable, +`NULL` is returned. See @ref glfwCreateStandardCursor for details. + + +@subsubsection cursor_destruction Cursor destruction + +When a cursor is no longer needed, destroy it with @ref glfwDestroyCursor. + +@code +glfwDestroyCursor(cursor); +@endcode + +Cursor destruction always succeeds. If the cursor is current for any window, +that window will revert to the default cursor. This does not affect the cursor +mode. All remaining cursors are destroyed when @ref glfwTerminate is called. + + +@subsubsection cursor_set Cursor setting + +A cursor can be set as current for a window with @ref glfwSetCursor. + +@code +glfwSetCursor(window, cursor); +@endcode + +Once set, the cursor image will be used as long as the system cursor is over the +content area of the window and the [cursor mode](@ref cursor_mode) is set +to `GLFW_CURSOR_NORMAL`. + +A single cursor may be set for any number of windows. + +To revert to the default cursor, set the cursor of that window to `NULL`. + +@code +glfwSetCursor(window, NULL); +@endcode + +When a cursor is destroyed, any window that has it set will revert to the +default cursor. This does not affect the cursor mode. + + +@subsection cursor_enter Cursor enter/leave events + +If you wish to be notified when the cursor enters or leaves the content area of +a window, set a cursor enter/leave callback. + +@code +glfwSetCursorEnterCallback(window, cursor_enter_callback); +@endcode + +The callback function receives the new classification of the cursor. + +@code +void cursor_enter_callback(GLFWwindow* window, int entered) +{ + if (entered) + { + // The cursor entered the content area of the window + } + else + { + // The cursor left the content area of the window + } +} +@endcode + +You can query whether the cursor is currently inside the content area of the +window with the [GLFW_HOVERED](@ref GLFW_HOVERED_attrib) window attribute. + +@code +if (glfwGetWindowAttrib(window, GLFW_HOVERED)) +{ + highlight_interface(); +} +@endcode + + +@subsection input_mouse_button Mouse button input + +If you wish to be notified when a mouse button is pressed or released, set +a mouse button callback. + +@code +glfwSetMouseButtonCallback(window, mouse_button_callback); +@endcode + +The callback function receives the [mouse button](@ref buttons), button action +and [modifier bits](@ref mods). + +@code +void mouse_button_callback(GLFWwindow* window, int button, int action, int mods) +{ + if (button == GLFW_MOUSE_BUTTON_RIGHT && action == GLFW_PRESS) + popup_menu(); +} +@endcode + +The action is one of `GLFW_PRESS` or `GLFW_RELEASE`. + +Mouse button states for [named buttons](@ref buttons) are also saved in +per-window state arrays that can be polled with @ref glfwGetMouseButton. + +@code +int state = glfwGetMouseButton(window, GLFW_MOUSE_BUTTON_LEFT); +if (state == GLFW_PRESS) +{ + upgrade_cow(); +} +@endcode + +The returned state is one of `GLFW_PRESS` or `GLFW_RELEASE`. + +This function only returns cached mouse button event state. It does not poll +the system for the current state of the mouse button. + +@anchor GLFW_STICKY_MOUSE_BUTTONS +Whenever you poll state, you risk missing the state change you are looking for. +If a pressed mouse button is released again before you poll its state, you will have +missed the button press. The recommended solution for this is to use a +mouse button callback, but there is also the `GLFW_STICKY_MOUSE_BUTTONS` +input mode. + +@code +glfwSetInputMode(window, GLFW_STICKY_MOUSE_BUTTONS, GLFW_TRUE); +@endcode + +When sticky mouse buttons mode is enabled, the pollable state of a mouse button +will remain `GLFW_PRESS` until the state of that button is polled with @ref +glfwGetMouseButton. Once it has been polled, if a mouse button release event +had been processed in the meantime, the state will reset to `GLFW_RELEASE`, +otherwise it will remain `GLFW_PRESS`. + +The `GLFW_MOUSE_BUTTON_LAST` constant holds the highest value of any +[named button](@ref buttons). + + +@subsection scrolling Scroll input + +If you wish to be notified when the user scrolls, whether with a mouse wheel or +touchpad gesture, set a scroll callback. + +@code +glfwSetScrollCallback(window, scroll_callback); +@endcode + +The callback function receives two-dimensional scroll offsets. + +@code +void scroll_callback(GLFWwindow* window, double xoffset, double yoffset) +{ +} +@endcode + +A normal mouse wheel, being vertical, provides offsets along the Y-axis. + + +@section joystick Joystick input + +The joystick functions expose connected joysticks and controllers, with both +referred to as joysticks. It supports up to sixteen joysticks, ranging from +`GLFW_JOYSTICK_1`, `GLFW_JOYSTICK_2` up to and including `GLFW_JOYSTICK_16` or +`GLFW_JOYSTICK_LAST`. You can test whether a [joystick](@ref joysticks) is +present with @ref glfwJoystickPresent. + +@code +int present = glfwJoystickPresent(GLFW_JOYSTICK_1); +@endcode + +Each joystick has zero or more axes, zero or more buttons, zero or more hats, +a human-readable name, a user pointer and an SDL compatible GUID. + +Detected joysticks are added to the beginning of the array. Once a joystick is +detected, it keeps its assigned ID until it is disconnected or the library is +terminated, so as joysticks are connected and disconnected, there may appear +gaps in the IDs. + +Joystick axis, button and hat state is updated when polled and does not require +a window to be created or events to be processed. However, if you want joystick +connection and disconnection events reliably delivered to the +[joystick callback](@ref joystick_event) then you must +[process events](@ref events). + +To see all the properties of all connected joysticks in real-time, run the +`joysticks` test program. + + +@subsection joystick_axis Joystick axis states + +The positions of all axes of a joystick are returned by @ref +glfwGetJoystickAxes. See the reference documentation for the lifetime of the +returned array. + +@code +int count; +const float* axes = glfwGetJoystickAxes(GLFW_JOYSTICK_5, &count); +@endcode + +Each element in the returned array is a value between -1.0 and 1.0. + + +@subsection joystick_button Joystick button states + +The states of all buttons of a joystick are returned by @ref +glfwGetJoystickButtons.

Their order may also vary +between platforms even with the same device. + +To solve this problem the SDL community crowdsourced the +[SDL_GameControllerDB](https://github.com/gabomdq/SDL_GameControllerDB) project, +a database of mappings from many different devices to an Xbox-like gamepad. + +GLFW supports this mapping format and contains a copy of the mappings +available at the time of release.

Newer ones can be added at runtime with @ref +glfwUpdateGamepadMappings. + +@code +const char* mappings = load_file_contents("game/data/gamecontrollerdb.txt"); + +glfwUpdateGamepadMappings(mappings); +@endcode + +This function supports everything from single lines up to and including the +unmodified contents of the whole `gamecontrollerdb.txt` file. + +If you are compiling GLFW from source with CMake you can update the built-in mappings by +building the _update_mappings_ target. This runs the `GenerateMappings.cmake` CMake +script, which downloads `gamecontrollerdb.txt` and regenerates the `mappings.h` header +file. + +Below is a description of the mapping format. Please keep in mind that __this +description is not authoritative__. The format is defined by the SDL and +SDL_GameControllerDB projects and their documentation and code takes precedence. + +Each mapping is a single line of comma-separated values describing the GUID, +name and layout of the gamepad. Lines that do not begin with a hexadecimal +digit are ignored. + +The first value is always the gamepad GUID, a 32 character long hexadecimal +string that typically identifies its make, model, revision and the type of +connection to the computer. When this information is not available, the GUID is +generated using the gamepad name. GLFW uses the SDL 2.0.5+ GUID format but can +convert from the older formats. + +The second value is always the human-readable name of the gamepad. + +All subsequent values are in the form `:` and describe the layout +of the mapping. These fields may not all be present and may occur in any order. + +The button fields are `a`, `b`, `x`, `y`, `back`, `start`, `guide`, `dpup`, +`dpright`, `dpdown`, `dpleft`, `leftshoulder`, `rightshoulder`, `leftstick` and +`rightstick`. + +The axis fields are `leftx`, `lefty`, `rightx`, `righty`, `lefttrigger` and +`righttrigger`. + +The value of an axis or button field can be a joystick button, a joystick axis, +a hat bitmask or empty. Joystick buttons are specified as `bN`, for example +`b2` for the third button. Joystick axes are specified as `aN`, for example +`a7` for the eighth button. Joystick hat bit masks are specified as `hN.N`, for +example `h0.8` for left on the first hat. More than one bit may be set in the +mask. + +Before an axis there may be a `+` or `-` range modifier, for example `+a3` for +the positive half of the fourth axis. This restricts input to only the positive +or negative halves of the joystick axis. After an axis or half-axis there may +be the `~` inversion modifier, for example `a2~` or `-a7~`. This negates the +values of the gamepad axis. + +The hat bit mask match the [hat states](@ref hat_state) in the joystick +functions. + +There is also the special `platform` field that specifies which platform the +mapping is valid for. Possible values are `Windows`, `Mac OS X` and `Linux`. + +Below is an example of what a gamepad mapping might look like. It is the +one built into GLFW for Xbox controllers accessed via the XInput API on Windows. +This example has been broken into several lines to fit on the page, but real +gamepad mappings must be a single line. + +@code{.unparsed} +78696e70757401000000000000000000,XInput Gamepad (GLFW),platform:Windows,a:b0, +b:b1,x:b2,y:b3,leftshoulder:b4,rightshoulder:b5,back:b6,start:b7,leftstick:b8, +rightstick:b9,leftx:a0,lefty:a1,rightx:a2,righty:a3,lefttrigger:a4, +righttrigger:a5,dpup:h0.1,dpright:h0.2,dpdown:h0.4,dpleft:h0.8, +@endcode + +@note GLFW does not yet support the output range and modifiers `+` and `-` that +were recently added to SDL.

This is done with @ref glfwTerminate. + +@code +glfwTerminate(); +@endcode + +This will destroy any remaining window, monitor and cursor objects, restore any +modified gamma ramps, re-enable the screensaver if it had been disabled and free +any other resources allocated by GLFW. + +Once the library is terminated, it is as if it had never been initialized and +you will need to initialize it again before being able to use GLFW. If the +library was not initialized or had already been terminated, it return +immediately. + + +@section error_handling Error handling + +Some GLFW functions have return values that indicate an error, but this is often +not very helpful when trying to figure out what happened or why it occurred. +Other functions have no return value reserved for errors, so error notification +needs a separate channel. Finally, far from all GLFW functions have return +values. + +The last [error code](@ref errors) for the calling thread can be queried at any +time with @ref glfwGetError. + +@code +int code = glfwGetError(NULL); + +if (code != GLFW_NO_ERROR) + handle_error(code); +@endcode + +If no error has occurred since the last call, @ref GLFW_NO_ERROR (zero) is +returned. The error is cleared before the function returns. + +The error code indicates the general category of the error. Some error codes, +such as @ref GLFW_NOT_INITIALIZED has only a single meaning, whereas others like +@ref GLFW_PLATFORM_ERROR are used for many different errors. + +GLFW often has more information about an error than its general category. You +can retrieve a UTF-8 encoded human-readable description along with the error +code. If no error has occurred since the last call, the description is set to +`NULL`. + +@code +const char* description; +int code = glfwGetError(&description); + +if (description) + display_error_message(code, description); +@endcode + +The retrieved description string is only valid until the next error occurs. +This means you must make a copy of it if you want to keep it. + +You can also set an error callback, which will be called each time an error +occurs. It is set with @ref glfwSetErrorCallback. + +@code +glfwSetErrorCallback(error_callback); +@endcode + +The error callback receives the same error code and human-readable description +returned by @ref glfwGetError. + +@code +void error_callback(int code, const char* description) +{ + display_error_message(code, description); +} +@endcode + +The error callback is called after the error is stored, so calling @ref +glfwGetError from within the error callback returns the same values as the +callback argument. + +The description string passed to the callback is only valid until the error +callback returns. This means you must make a copy of it if you want to keep it. + +__Reported errors are never fatal.__ As long as GLFW was successfully +initialized, it will remain initialized and in a safe state until terminated +regardless of how many errors occur. If an error occurs during initialization +that causes @ref glfwInit to fail, any part of the library that was initialized +will be safely terminated. + +Do not rely on a currently invalid call to generate a specific error, as in the +future that same call may generate a different error or become valid. + + +@section coordinate_systems Coordinate systems + +GLFW has two primary coordinate systems: the _virtual screen_ and the window +_content area_ or _content area_. Both use the same unit: _virtual screen +coordinates_, or just _screen coordinates_, which don't necessarily correspond +to pixels. + + + +Both the virtual screen and the content area coordinate systems have the X-axis +pointing to the right and the Y-axis pointing down. + +Window and monitor positions are specified as the position of the upper-left +corners of their content areas relative to the virtual screen, while cursor +positions are specified relative to a window's content area. + +Because the origin of the window's content area coordinate system is also the +point from which the window position is specified, you can translate content +area coordinates to the virtual screen by adding the window position. The +window frame, when present, extends out from the content area but does not +affect the window position. + +Almost all positions and sizes in GLFW are measured in screen coordinates +relative to one of the two origins above. This includes cursor positions, +window positions and sizes, window frame sizes, monitor positions and video mode +resolutions. + +Two exceptions are the [monitor physical size](@ref monitor_size), which is +measured in millimetres, and [framebuffer size](@ref window_fbsize), which is +measured in pixels. + +Pixels and screen coordinates may map 1:1 on your machine, but they won't on +every other machine, for example on a Mac with a Retina display. The ratio +between screen coordinates and pixels may also change at run-time depending on +which monitor the window is currently considered to be on. + + +@section guarantees_limitations Guarantees and limitations + +This section describes the conditions under which GLFW can be expected to +function, barring bugs in the operating system or drivers. Use of GLFW outside +of these limits may work on some platforms, or on some machines, or some of the +time, or on some versions of GLFW, but it may break at any time and this will +not be considered a bug. + + +@subsection lifetime Pointer lifetimes + +GLFW will never free any pointer you provide to it and you must never free any +pointer it provides to you. + +Many GLFW functions return pointers to dynamically allocated structures, strings +or arrays, and some callbacks are provided with strings or arrays. These are +always managed by GLFW and should never be freed by the application. The +lifetime of these pointers is documented for each GLFW function and callback. +If you need to keep this data, you must copy it before its lifetime expires. + +Many GLFW functions accept pointers to structures or strings allocated by the +application. These are never freed by GLFW and are always the responsibility of +the application. If GLFW needs to keep the data in these structures or strings, +it is copied before the function returns. + +Pointer lifetimes are guaranteed not to be shortened in future minor or patch +releases. + + +@subsection reentrancy Reentrancy + +GLFW event processing and object destruction are not reentrant. This means that +the following functions must not be called from any callback function: + + - @ref glfwDestroyWindow + - @ref glfwDestroyCursor + - @ref glfwPollEvents + - @ref glfwWaitEvents + - @ref glfwWaitEventsTimeout + - @ref glfwTerminate + +These functions may be made reentrant in future minor or patch releases, but +functions not on this list will not be made non-reentrant. + + +@subsection thread_safety Thread safety + +Most GLFW functions must only be called from the main thread (the thread that +calls main), but some may be called from any thread once the library has been +initialized. Before initialization the whole library is thread-unsafe. + +The reference documentation for every GLFW function states whether it is limited +to the main thread. + +Initialization, termination, event processing and the creation and +destruction of windows, cursors and OpenGL and OpenGL ES contexts are all +restricted to the main thread due to limitations of one or several platforms. + +Because event processing must be performed on the main thread, all callbacks +except for the error callback will only be called on that thread. The error +callback may be called on any thread, as any GLFW function may generate errors. + +The error code and description may be queried from any thread. + + - @ref glfwGetError + +Empty events may be posted from any thread. + + - @ref glfwPostEmptyEvent + +The window user pointer and close flag may be read and written from any thread, +but this is not synchronized by GLFW. + + - @ref glfwGetWindowUserPointer + - @ref glfwSetWindowUserPointer + - @ref glfwWindowShouldClose + - @ref glfwSetWindowShouldClose + +These functions for working with OpenGL and OpenGL ES contexts may be called +from any thread, but the window object is not synchronized by GLFW. + + - @ref glfwMakeContextCurrent + - @ref glfwGetCurrentContext + - @ref glfwSwapBuffers + - @ref glfwSwapInterval + - @ref glfwExtensionSupported + - @ref glfwGetProcAddress + +The raw timer functions may be called from any thread. + + - @ref glfwGetTimerFrequency + - @ref glfwGetTimerValue + +The regular timer may be used from any thread, but reading and writing the timer +offset is not synchronized by GLFW. + + - @ref glfwGetTime + - @ref glfwSetTime + +Library version information may be queried from any thread. + + - @ref glfwGetVersion + - @ref glfwGetVersionString + +Platform information may be queried from any thread. + + - @ref glfwPlatformSupported + - @ref glfwGetPlatform + +All Vulkan related functions may be called from any thread. + + - @ref glfwVulkanSupported + - @ref glfwGetRequiredInstanceExtensions + - @ref glfwGetInstanceProcAddress + - @ref glfwGetPhysicalDevicePresentationSupport + - @ref glfwCreateWindowSurface + +GLFW uses synchronization objects internally only to manage the per-thread +context and error states. Additional synchronization is left to the +application. + +Functions that may currently be called from any thread will always remain so, +but functions that are currently limited to the main thread may be updated to +allow calls from any thread in future releases. + + +@subsection compatibility Version compatibility + +GLFW uses [Semantic Versioning](https://semver.org/). This guarantees source +and binary backward compatibility with earlier minor versions of the API. This +means that you can drop in a newer version of the library and existing programs +will continue to compile and existing binaries will continue to run. + +Once a function or constant has been added, the signature of that function or +value of that constant will remain unchanged until the next major version of +GLFW. No compatibility of any kind is guaranteed between major versions. + +Undocumented behavior, i.e. behavior that is not described in the documentation, +may change at any time until it is documented. + +If the reference documentation and the implementation differ, the reference +documentation will almost always take precedence and the implementation will be +fixed in the next release. The reference documentation will also take +precedence over anything stated in a guide. + + +@subsection event_order Event order + +The order of arrival of related events is not guaranteed to be consistent +across platforms. The exception is synthetic key and mouse button release +events, which are always delivered after the window defocus event. + + +@section intro_version Version management + +GLFW provides mechanisms for identifying what version of GLFW your application +was compiled against as well as what version it is currently running against. +If you are loading GLFW dynamically (not just linking dynamically), you can use +this to verify that the library binary is compatible with your application. + + +@subsection intro_version_compile Compile-time version + +The compile-time version of GLFW is provided by the GLFW header with the +`GLFW_VERSION_MAJOR`, `GLFW_VERSION_MINOR` and `GLFW_VERSION_REVISION` macros. + +@code +printf("Compiled against GLFW %i.%i.%i\n", + GLFW_VERSION_MAJOR, + GLFW_VERSION_MINOR, + GLFW_VERSION_REVISION); +@endcode + + +@subsection intro_version_runtime Run-time version + +The run-time version can be retrieved with @ref glfwGetVersion, a function that +may be called regardless of whether GLFW is initialized. + +@code +int major, minor, revision; +glfwGetVersion(&major, &minor, &revision); + +printf("Running against GLFW %i.%i.%i\n", major, minor, revision); +@endcode + + +@subsection intro_version_string Version string + +GLFW 3 also provides a compile-time generated version string that describes the +version, platform, compiler and any platform-specific compile-time options. +This is primarily intended for submitting bug reports, to allow developers to +see which code paths are enabled in a binary. + +The version string is returned by @ref glfwGetVersionString, a function that may +be called regardless of whether GLFW is initialized. + +__Do not use the version string__ to parse the GLFW library version.

There are +better threading libraries available and native threading support is available +in both [C++11](https://en.cppreference.com/w/cpp/thread) and +[C11](https://en.cppreference.com/w/c/thread), both of which are gaining +traction. + +If you wish to use the C++11 or C11 facilities but your compiler doesn't yet +support them, see the +[TinyThread++](https://gitorious.org/tinythread/tinythreadpp) and +[TinyCThread](https://github.com/tinycthread/tinycthread) projects created by +the original author of GLFW.

They only supported +the Targa image format, making them mostly useful for beginner level examples. +To become of sufficiently high quality to warrant keeping them in GLFW 3, they +would need not only to support other formats, but also modern extensions to +OpenGL texturing. This would either add a number of external +dependencies (libjpeg, libpng, etc.), or force GLFW to ship with inline versions +of these libraries. + +As there already are libraries doing this, it is unnecessary both to duplicate +the work and to tie the duplicate to GLFW.

Therefore, GLFW 3 leaves that decision to you. + +This means that you need to call @ref glfwMakeContextCurrent after creating +a window before you can call any OpenGL functions. + + +@subsection moving_hidpi Separation of window and framebuffer sizes + +Window positions and sizes now use screen coordinates, which may not be the same +as pixels on machines with high-DPI monitors. This is important as OpenGL uses +pixels, not screen coordinates. For example, the rectangle specified with +`glViewport` needs to use pixels. Therefore, framebuffer size functions have +been added. You can retrieve the size of the framebuffer of a window with @ref +glfwGetFramebufferSize function.

As long as the window has +not been destroyed, whether through @ref glfwDestroyWindow or @ref +glfwTerminate, the window is "open". + +A user attempting to close a window is now just an event like any other. Unlike +GLFW 2, windows and contexts created with GLFW 3 will never be destroyed unless +you choose them to be. Each window now has a close flag that is set to +`GLFW_TRUE` when the user attempts to close that window. By default, nothing else +happens and the window stays visible. It is then up to you to either destroy +the window, take some other action or ignore the request. + +You can query the close flag at any time with @ref glfwWindowShouldClose and set +it at any time with @ref glfwSetWindowShouldClose. + +@par Old basic main loop +@code +while (glfwGetWindowParam(GLFW_OPENED)) +{ + ... +} +@endcode + +@par New basic main loop +@code +while (!glfwWindowShouldClose(window)) +{ + ... +} +@endcode + +The close callback no longer returns a value.

The @ref glfwGetVideoModes function +now returns all available modes for a specific monitor instead of requiring you +to guess how large an array you need. The `glfwGetDesktopMode` function, which +had poorly defined behavior, has been replaced by @ref glfwGetVideoMode, which +returns the current mode of a monitor. + + +@subsection moving_char_up Removal of character actions + +The action parameter of the [character callback](@ref GLFWcharfun) has been +removed. This was an artefact of the origin of GLFW, i.e. being developed in +English by a Swede. However, many keyboard layouts require more than one key to +produce characters with diacritical marks. Even the Swedish keyboard layout +requires this for uncommon cases like ü. + +@par Old syntax +@code +void GLFWCALL character_callback(int character, int action); +@endcode + +@par New syntax +@code +void character_callback(GLFWwindow* window, int character); +@endcode + + +@subsection moving_cursorpos Cursor position changes + +The `glfwGetMousePos` function has been renamed to @ref glfwGetCursorPos, +`glfwSetMousePos` to @ref glfwSetCursorPos and `glfwSetMousePosCallback` to @ref +glfwSetCursorPosCallback. + +The cursor position is now `double` instead of `int`, both for the direct +functions and for the callback. Some platforms can provide sub-pixel cursor +movement and this data is now passed on to the application where available. On +platforms where this is not provided, the decimal part is zero. + +GLFW 3 only allows you to position the cursor within a window using @ref +glfwSetCursorPos (formerly `glfwSetMousePos`) when that window is active. +Unless the window is active, the function fails silently. + + +@subsection moving_wheel Wheel position replaced by scroll offsets + +The `glfwGetMouseWheel` function has been removed. Scrolling is the input of +offsets and has no absolute position. The mouse wheel callback has been +replaced by a [scroll callback](@ref GLFWscrollfun) that receives +two-dimensional floating point scroll offsets. This allows you to receive +precise scroll data from for example modern touchpads. + +@par Old syntax +@code +void GLFWCALL mouse_wheel_callback(int position); +@endcode + +@par New syntax +@code +void scroll_callback(GLFWwindow* window, double xoffset, double yoffset); +@endcode + +@par Removed functions +`glfwGetMouseWheel` + + +@subsection moving_repeat Key repeat action + +The `GLFW_KEY_REPEAT` enable has been removed and key repeat is always enabled +for both keys and characters. A new key action, `GLFW_REPEAT`, has been added +to allow the [key callback](@ref GLFWkeyfun) to distinguish an initial key press +from a repeat. Note that @ref glfwGetKey still returns only `GLFW_PRESS` or +`GLFW_RELEASE`. + + +@subsection moving_keys Physical key input + +GLFW 3 key tokens map to physical keys, unlike in GLFW 2 where they mapped to +the values generated by the current keyboard layout. The tokens are named +according to the values they would have using the standard US layout, but this +is only a convenience, as most programmers are assumed to know that layout. +This means that (for example) `GLFW_KEY_LEFT_BRACKET` is always a single key and +is the same key in the same place regardless of what keyboard layouts the users +of your program has. + +The key input facility was never meant for text input, although using it that +way worked slightly better in GLFW 2. If you were using it to input text, you +should be using the character callback instead, on both GLFW 2 and 3. This will +give you the characters being input, as opposed to the keys being pressed. + +GLFW 3 has key tokens for all keys on a standard 105 key keyboard, so instead of +having to remember whether to check for `a` or `A`, you now check for +@ref GLFW_KEY_A. + + +@subsection moving_joystick Joystick function changes + +The `glfwGetJoystickPos` function has been renamed to @ref glfwGetJoystickAxes. + +The `glfwGetJoystickParam` function and the `GLFW_PRESENT`, `GLFW_AXES` and +`GLFW_BUTTONS` tokens have been replaced by the @ref glfwJoystickPresent +function as well as axis and button counts returned by the @ref +glfwGetJoystickAxes and @ref glfwGetJoystickButtons functions. + + +@subsection moving_mbcs Win32 MBCS support + +The Win32 port of GLFW 3 will not compile in +[MBCS mode](https://msdn.microsoft.com/en-us/library/5z097dxa.aspx). +However, because the use of the Unicode version of the Win32 API doesn't affect +the process as a whole, but only those windows created using it, it's perfectly +possible to call MBCS functions from other parts of the same application. +Therefore, even if an application using GLFW has MBCS mode code, there's no need +for GLFW itself to support it. + + +@subsection moving_windows Support for versions of Windows older than XP + +All explicit support for version of Windows older than XP has been removed. +There is no code that actively prevents GLFW 3 from running on these earlier +versions, but it uses Win32 functions that those versions lack. + +Windows XP was released in 2001, and by now (January 2015) it has not only +replaced almost all earlier versions of Windows, but is itself rapidly being +replaced by Windows 7 and 8. The MSDN library doesn't even provide +documentation for version older than Windows 2000, making it difficult to +maintain compatibility with these versions even if it was deemed worth the +effort. + +The Win32 API has also not stood still, and GLFW 3 uses many functions only +present on Windows XP or later. Even supporting an OS as new as XP (new +from the perspective of GLFW 2, which still supports Windows 95) requires +runtime checking for a number of functions that are present only on modern +version of Windows. + + +@subsection moving_syskeys Capture of system-wide hotkeys + +The ability to disable and capture system-wide hotkeys like Alt+Tab has been +removed. Modern applications, whether they're games, scientific visualisations +or something else, are nowadays expected to be good desktop citizens and allow +these hotkeys to function even when running in full screen mode. + + +@subsection moving_terminate Automatic termination + +GLFW 3 does not register @ref glfwTerminate with `atexit` at initialization, +because `exit` calls registered functions from the calling thread and while it +is permitted to call `exit` from any thread, @ref glfwTerminate must only be +called from the main thread. + +To release all resources allocated by GLFW, you should call @ref glfwTerminate +yourself, from the main thread, before the program terminates. Note that this +destroys all windows not already destroyed with @ref glfwDestroyWindow, +invalidating any window handles you may still have. + + +@subsection moving_glu GLU header inclusion + +GLFW 3 does not by default include the GLU header and GLU itself has been +deprecated by [Khronos](https://en.wikipedia.org/wiki/Khronos_Group). __New +projects should not use GLU__, but if you need it for legacy code that +has been moved to GLFW 3, you can request that the GLFW header includes it by +defining @ref GLFW_INCLUDE_GLU before the inclusion of the GLFW header. + +@par Old syntax +@code +#include +@endcode + +@par New syntax +@code +#define GLFW_INCLUDE_GLU +#include +@endcode + +There are many libraries that offer replacements for the functionality offered +by GLU.

The +application will create a window and OpenGL context, render a rotating triangle +and exit when the user closes the window or presses _Escape_. This guide will +introduce a few of the most commonly used functions, but there are many more. + +This guide assumes no experience with earlier versions of GLFW. If you +have used GLFW 2 in the past, read @ref moving_guide, as some functions +behave differently in GLFW 3. + + +@section quick_steps Step by step + +@subsection quick_include Including the GLFW header + +In the source files of your application where you use GLFW, you need to include +its header file. + +@code +#include +@endcode + +This header provides all the constants, types and function prototypes of the +GLFW API. + +By default it also includes the OpenGL header from your development environment. +On some platforms this header only supports older versions of OpenGL. The most +extreme case is Windows, where it typically only supports OpenGL 1.2. + +Most programs will instead use an +[extension loader library](@ref context_glext_auto) and include its header. +This example uses files generated by [glad](https://gen.glad.sh/). The GLFW +header can detect most such headers if they are included first and will then not +include the one from your development environment. + +@code +#include +#include +@endcode + +To make sure there will be no header conflicts, you can define @ref +GLFW_INCLUDE_NONE before the GLFW header to explicitly disable inclusion of the +development environment header. This also allows the two headers to be included +in any order. + +@code +#define GLFW_INCLUDE_NONE +#include +#include +@endcode + + +@subsection quick_init_term Initializing and terminating GLFW + +Before you can use most GLFW functions, the library must be initialized. On +successful initialization, `GLFW_TRUE` is returned. If an error occurred, +`GLFW_FALSE` is returned. + +@code +if (!glfwInit()) +{ + // Initialization failed +} +@endcode + +Note that `GLFW_TRUE` and `GLFW_FALSE` are and will always be one and zero. + +When you are done using GLFW, typically just before the application exits, you +need to terminate GLFW. + +@code +glfwTerminate(); +@endcode + +This destroys any remaining windows and releases any other resources allocated by +GLFW. After this call, you must initialize GLFW again before using any GLFW +functions that require it. + + +@subsection quick_capture_error Setting an error callback + +Most events are reported through callbacks, whether it's a key being pressed, +a GLFW window being moved, or an error occurring. Callbacks are C functions (or +C++ static methods) that are called by GLFW with arguments describing the event. + +In case a GLFW function fails, an error is reported to the GLFW error callback. +You can receive these reports with an error callback. This function must have +the signature below but may do anything permitted in other callbacks. + +@code +void error_callback(int error, const char* description) +{ + fprintf(stderr, "Error: %s\n", description); +} +@endcode + +Callback functions must be set, so GLFW knows to call them. The function to set +the error callback is one of the few GLFW functions that may be called before +initialization, which lets you be notified of errors both during and after +initialization. + +@code +glfwSetErrorCallback(error_callback); +@endcode + + +@subsection quick_create_window Creating a window and context + +The window and its OpenGL context are created with a single call to @ref +glfwCreateWindow, which returns a handle to the created combined window and +context object + +@code +GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL); +if (!window) +{ + // Window or OpenGL context creation failed +} +@endcode + +This creates a 640 by 480 windowed mode window with an OpenGL context. If +window or OpenGL context creation fails, `NULL` will be returned. You should +always check the return value. While window creation rarely fails, context +creation depends on properly installed drivers and may fail even on machines +with the necessary hardware. + +By default, the OpenGL context GLFW creates may have any version. You can +require a minimum OpenGL version by setting the `GLFW_CONTEXT_VERSION_MAJOR` and +`GLFW_CONTEXT_VERSION_MINOR` hints _before_ creation. If the required minimum +version is not supported on the machine, context (and window) creation fails. + +You can select the OpenGL profile by setting the `GLFW_OPENGL_PROFILE` hint. +This program uses the core profile as that is the only profile macOS supports +for OpenGL 3.x and 4.x. + +@code +glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3); +glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3); +glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); +GLFWwindow* window = glfwCreateWindow(640, 480, "My Title", NULL, NULL); +if (!window) +{ + // Window or context creation failed +} +@endcode + +The window handle is passed to all window related functions and is provided to +along to all window related callbacks, so they can tell which window received +the event. + +When a window and context is no longer needed, destroy it. + +@code +glfwDestroyWindow(window); +@endcode + +Once this function is called, no more events will be delivered for that window +and its handle becomes invalid. + + +@subsection quick_context_current Making the OpenGL context current + +Before you can use the OpenGL API, you must have a current OpenGL context. + +@code +glfwMakeContextCurrent(window); +@endcode + +The context will remain current until you make another context current or until +the window owning the current context is destroyed. + +If you are using an [extension loader library](@ref context_glext_auto) to +access modern OpenGL then this is when to initialize it, as the loader needs +a current context to load from. This example uses +[glad](https://github.com/Dav1dde/glad), but the same rule applies to all such +libraries. + +@code +gladLoadGL(glfwGetProcAddress); +@endcode + + +@subsection quick_window_close Checking the window close flag + +Each window has a flag indicating whether the window should be closed. + +When the user attempts to close the window, either by pressing the close widget +in the title bar or using a key combination like Alt+F4, this flag is set to 1. +Note that __the window isn't actually closed__, so you are expected to monitor +this flag and either destroy the window or give some kind of feedback to the +user. + +@code +while (!glfwWindowShouldClose(window)) +{ + // Keep running +} +@endcode + +You can be notified when the user is attempting to close the window by setting +a close callback with @ref glfwSetWindowCloseCallback. The callback will be +called immediately after the close flag has been set. + +You can also set it yourself with @ref glfwSetWindowShouldClose. This can be +useful if you want to interpret other kinds of input as closing the window, like +for example pressing the _Escape_ key. + + +@subsection quick_key_input Receiving input events + +Each window has a large number of callbacks that can be set to receive all the +various kinds of events. To receive key press and release events, create a key +callback function. + +@code +static void key_callback(GLFWwindow* window, int key, int scancode, int action, int mods) +{ + if (key == GLFW_KEY_ESCAPE && action == GLFW_PRESS) + glfwSetWindowShouldClose(window, GLFW_TRUE); +} +@endcode + +The key callback, like other window related callbacks, are set per-window. + +@code +glfwSetKeyCallback(window, key_callback); +@endcode + +In order for event callbacks to be called when events occur, you need to process +events as described below. + + +@subsection quick_render Rendering with OpenGL + +Once you have a current OpenGL context, you can use OpenGL normally. In this +tutorial, a multi-colored rotating triangle will be rendered. The framebuffer +size needs to be retrieved for `glViewport`. + +@code +int width, height; +glfwGetFramebufferSize(window, &width, &height); +glViewport(0, 0, width, height); +@endcode + +You can also set a framebuffer size callback using @ref +glfwSetFramebufferSizeCallback and be notified when the size changes. + +The details of how to render with OpenGL is outside the scope of this tutorial, +but there are many excellent resources for learning modern OpenGL. Here are +a few of them: + + - [Anton's OpenGL 4 Tutorials](https://antongerdelan.net/opengl/) + - [Learn OpenGL](https://learnopengl.com/) + - [Open.GL](https://open.gl/) + +These all happen to use GLFW, but OpenGL itself works the same whatever API you +use to create the window and context. + + +@subsection quick_timer Reading the timer + +To create smooth animation, a time source is needed. GLFW provides a timer that +returns the number of seconds since initialization. The time source used is the +most accurate on each platform and generally has micro- or nanosecond +resolution. + +@code +double time = glfwGetTime(); +@endcode + + +@subsection quick_swap_buffers Swapping buffers + +GLFW windows by default use double buffering. That means that each window has +two rendering buffers; a front buffer and a back buffer. The front buffer is +the one being displayed and the back buffer the one you render to. + +When the entire frame has been rendered, the buffers need to be swapped with one +another, so the back buffer becomes the front buffer and vice versa. + +@code +glfwSwapBuffers(window); +@endcode + +The swap interval indicates how many frames to wait until swapping the buffers, +commonly known as _vsync_. By default, the swap interval is zero, meaning +buffer swapping will occur immediately. On fast machines, many of those frames +will never be seen, as the screen is still only updated typically 60-75 times +per second, so this wastes a lot of CPU and GPU cycles. + +Also, because the buffers will be swapped in the middle the screen update, +leading to [screen tearing](https://en.wikipedia.org/wiki/Screen_tearing). + +For these reasons, applications will typically want to set the swap interval to +one. It can be set to higher values, but this is usually not recommended, +because of the input latency it leads to. + +@code +glfwSwapInterval(1); +@endcode + +This function acts on the current context and will fail unless a context is +current. + + +@subsection quick_process_events Processing events + +GLFW needs to communicate regularly with the window system both in order to +receive events and to show that the application hasn't locked up. Event +processing must be done regularly while you have visible windows and is normally +done each frame after buffer swapping. + +There are two methods for processing pending events; polling and waiting. This +example will use event polling, which processes only those events that have +already been received and then returns immediately. + +@code +glfwPollEvents(); +@endcode + +This is the best choice when rendering continually, like most games do. If +instead you only need to update your rendering once you have received new input, +@ref glfwWaitEvents is a better choice. It waits until at least one event has +been received, putting the thread to sleep in the meantime, and then processes +all received events. This saves a great deal of CPU cycles and is useful for, +for example, many kinds of editing tools. + + +@section quick_example Putting it together + +Now that you know how to initialize GLFW, create a window and poll for +keyboard input, it's possible to create a small program. + +This program creates a 640 by 480 windowed mode window and starts a loop that +clears the screen, renders a triangle and processes events until the user either +presses _Escape_ or closes the window. + +@snippet triangle-opengl.c code + +The program above can be found in the +[source package](https://www.glfw.org/download.html) as +`examples/triangle-opengl.c` and is compiled along with all other examples when +you build GLFW. If you built GLFW from the source package then you already have +this as `triangle-opengl.exe` on Windows, `triangle-opengl` on Linux or +`triangle-opengl.app` on macOS. + +This tutorial used only a few of the many functions GLFW provides. There are +guides for each of the areas covered by GLFW. Each guide will introduce all the +functions for that category. + + - @ref intro_guide + - @ref window_guide + - @ref context_guide + - @ref monitor_guide + - @ref input_guide + +You can access reference documentation for any GLFW function by clicking it and +the reference for each function links to related functions and guide sections. + +The tutorial ends here.

Possible values are `GLFW_TRUE` and `GLFW_FALSE`. +This hint is ignored for full screen windows. + +@anchor GLFW_FOCUSED_hint +__GLFW_FOCUSED__ specifies whether the windowed mode window will be given input +focus when created. Possible values are `GLFW_TRUE` and `GLFW_FALSE`. This +hint is ignored for full screen and initially hidden windows. + +@anchor GLFW_AUTO_ICONIFY_hint +__GLFW_AUTO_ICONIFY__ specifies whether the full screen window will +automatically iconify and restore the previous video mode on input focus loss. +Possible values are `GLFW_TRUE` and `GLFW_FALSE`.

Possible values are `GLFW_TRUE` and +`GLFW_FALSE`. + +@anchor GLFW_FOCUS_ON_SHOW_hint +__GLFW_FOCUS_ON_SHOW__ specifies whether the window will be given input +focus when @ref glfwShowWindow is called. Possible values are `GLFW_TRUE` and +`GLFW_FALSE`. + +@anchor GLFW_SCALE_TO_MONITOR +__GLFW_SCALE_TO_MONITOR__ specified whether the window content area should be +resized based on the [monitor content scale](@ref monitor_scale) of any monitor +it is placed on. This includes the initial placement when the window is +created. Possible values are `GLFW_TRUE` and `GLFW_FALSE`. + +This hint only has an effect on platforms where screen coordinates and pixels +always map 1:1 such as Windows and X11. On platforms like macOS the resolution +of the framebuffer is changed independently of the window size. + +@anchor GLFW_MOUSE_PASSTHROUGH_hint +__GLFW_MOUSE_PASSTHROUGH__ specifies whether the window is transparent to mouse +input, letting any mouse events pass through to whatever window is behind it. +This is only supported for undecorated windows.

A value +of `GLFW_DONT_CARE` means the application has no preference. + +Auxiliary buffers are a legacy OpenGL feature and should not be used in new +code. + +@anchor GLFW_STEREO +__GLFW_STEREO__ specifies whether to use OpenGL stereoscopic rendering. +Possible values are `GLFW_TRUE` and `GLFW_FALSE`. This is a hard constraint. + +@anchor GLFW_SAMPLES +__GLFW_SAMPLES__ specifies the desired number of samples to use for +multisampling. Zero disables multisampling. A value of `GLFW_DONT_CARE` means +the application has no preference. + +@anchor GLFW_SRGB_CAPABLE +__GLFW_SRGB_CAPABLE__ specifies whether the framebuffer should be sRGB capable. +Possible values are `GLFW_TRUE` and `GLFW_FALSE`. + +@note __OpenGL:__ If enabled and supported by the system, the +`GL_FRAMEBUFFER_SRGB` enable will control sRGB rendering. By default, sRGB +rendering will be disabled. + +@note __OpenGL ES:__ If enabled and supported by the system, the context will +always have sRGB rendering enabled. + +@anchor GLFW_DOUBLEBUFFER +@anchor GLFW_DOUBLEBUFFER_hint +__GLFW_DOUBLEBUFFER__ specifies whether the framebuffer should be double +buffered. You nearly always want to use double buffering. This is a hard +constraint. Possible values are `GLFW_TRUE` and `GLFW_FALSE`. + + +@subsubsection window_hints_mtr Monitor related hints + +@anchor GLFW_REFRESH_RATE +__GLFW_REFRESH_RATE__ specifies the desired refresh rate for full screen +windows.

This hint is ignored for windowed mode windows. + + +@subsubsection window_hints_ctx Context related hints + +@anchor GLFW_CLIENT_API_hint +__GLFW_CLIENT_API__ specifies which client API to create the context for. +Possible values are `GLFW_OPENGL_API`, `GLFW_OPENGL_ES_API` and `GLFW_NO_API`. +This is a hard constraint. + +@anchor GLFW_CONTEXT_CREATION_API_hint +__GLFW_CONTEXT_CREATION_API__ specifies which context creation API to use to +create the context. Possible values are `GLFW_NATIVE_CONTEXT_API`, +`GLFW_EGL_CONTEXT_API` and `GLFW_OSMESA_CONTEXT_API`. This is a hard +constraint. If no client API is requested, this hint is ignored. + +An [extension loader library](@ref context_glext_auto) that assumes it knows +which API was used to create the current context may fail if you change this +hint. This can be resolved by having it load functions via @ref +glfwGetProcAddress. + +@note @wayland The EGL API _is_ the native context creation API, so this hint +will have no effect. + +@note @x11 On some Linux systems, creating contexts via both the native and EGL +APIs in a single process will cause the application to segfault. Stick to one +API or the other on Linux for now. + +@note __OSMesa:__ As its name implies, an OpenGL context created with OSMesa +does not update the window contents when its buffers are swapped.

The exact +behavior of these hints depend on the requested client API. + +While there is no way to ask the driver for a context of the highest supported +version, GLFW will attempt to provide this when you ask for a version 1.0 +context, which is the default for these hints. + +Do not confuse these hints with @ref GLFW_VERSION_MAJOR and @ref +GLFW_VERSION_MINOR, which provide the API version of the GLFW header. + +@note __OpenGL:__ These hints are not hard constraints, but creation will fail +if the OpenGL version of the created context is less than the one requested. It +is therefore perfectly safe to use the default of version 1.0 for legacy code +and you will still get backwards-compatible contexts of version 3.0 and above +when available. + +@note __OpenGL ES:__ These hints are not hard constraints, but creation will +fail if the OpenGL ES version of the created context is less than the one +requested. Additionally, OpenGL ES 1.x cannot be returned if 2.0 or later was +requested, and vice versa. This is because OpenGL ES 3.x is backward compatible +with 2.0, but OpenGL ES 2.0 is not backward compatible with 1.x. + +@note @macos The OS only supports core profile contexts for OpenGL versions 3.2 +and later. Before creating an OpenGL context of version 3.2 or later you must +set the [GLFW_OPENGL_PROFILE](@ref GLFW_OPENGL_PROFILE_hint) hint accordingly. +OpenGL 3.0 and 3.1 contexts are not supported at all on macOS. + +@anchor GLFW_OPENGL_FORWARD_COMPAT_hint +__GLFW_OPENGL_FORWARD_COMPAT__ specifies whether the OpenGL context should be +forward-compatible, i.e. one where all functionality deprecated in the requested +version of OpenGL is removed. This must only be used if the requested OpenGL +version is 3.0 or above. If OpenGL ES is requested, this hint is ignored. + +Forward-compatibility is described in detail in the +[OpenGL Reference Manual](https://www.opengl.org/registry/). + +@anchor GLFW_CONTEXT_DEBUG_hint +@anchor GLFW_OPENGL_DEBUG_CONTEXT_hint +__GLFW_CONTEXT_DEBUG__ specifies whether the context should be created in debug +mode, which may provide additional error and diagnostic reporting functionality. +Possible values are `GLFW_TRUE` and `GLFW_FALSE`. + +Debug contexts for OpenGL and OpenGL ES are described in detail by the +[GL_KHR_debug](https://www.khronos.org/registry/OpenGL/extensions/KHR/KHR_debug.txt) +extension. + +@note `GLFW_CONTEXT_DEBUG` is the new name introduced in GLFW 3.4. The older +`GLFW_OPENGL_DEBUG_CONTEXT` name is also available for compatibility. + +@anchor GLFW_OPENGL_PROFILE_hint +__GLFW_OPENGL_PROFILE__ specifies which OpenGL profile to create the context +for. Possible values are one of `GLFW_OPENGL_CORE_PROFILE` or +`GLFW_OPENGL_COMPAT_PROFILE`, or `GLFW_OPENGL_ANY_PROFILE` to not request +a specific profile. If requesting an OpenGL version below 3.2, +`GLFW_OPENGL_ANY_PROFILE` must be used. If OpenGL ES is requested, this hint +is ignored. + +OpenGL profiles are described in detail in the +[OpenGL Reference Manual](https://www.opengl.org/registry/). + +@anchor GLFW_CONTEXT_ROBUSTNESS_hint +__GLFW_CONTEXT_ROBUSTNESS__ specifies the robustness strategy to be used by the +context. This can be one of `GLFW_NO_RESET_NOTIFICATION` or +`GLFW_LOSE_CONTEXT_ON_RESET`, or `GLFW_NO_ROBUSTNESS` to not request +a robustness strategy. + +@anchor GLFW_CONTEXT_RELEASE_BEHAVIOR_hint +__GLFW_CONTEXT_RELEASE_BEHAVIOR__ specifies the release behavior to be +used by the context. Possible values are one of `GLFW_ANY_RELEASE_BEHAVIOR`, +`GLFW_RELEASE_BEHAVIOR_FLUSH` or `GLFW_RELEASE_BEHAVIOR_NONE`. If the +behavior is `GLFW_ANY_RELEASE_BEHAVIOR`, the default behavior of the context +creation API will be used. If the behavior is `GLFW_RELEASE_BEHAVIOR_FLUSH`, +the pipeline will be flushed whenever the context is released from being the +current one.

A single window may not use both methods. The +results of doing this are undefined. + +Both methods require the platform to support it and not every version of every +platform GLFW supports does this, so there are mechanisms to check whether the +window really is transparent. + +Window framebuffers can be made transparent on a per-pixel per-frame basis with +the [GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_hint) +window hint. + +@code +glfwWindowHint(GLFW_TRANSPARENT_FRAMEBUFFER, GLFW_TRUE); +@endcode + +If supported by the system, the window content area will be composited with the +background using the framebuffer per-pixel alpha channel.

This +is `GLFW_OPENGL_CORE_PROFILE` or `GLFW_OPENGL_COMPAT_PROFILE` if the context +uses a known profile, or `GLFW_OPENGL_ANY_PROFILE` if the OpenGL profile is +unknown or the context is an OpenGL ES context. Note that the returned profile +may not match the profile bits of the context flags, as GLFW will try other +means of detecting the profile when no bits are set. + +@anchor GLFW_CONTEXT_RELEASE_BEHAVIOR_attrib +__GLFW_CONTEXT_RELEASE_BEHAVIOR__ indicates the release used by the context. +Possible values are one of `GLFW_ANY_RELEASE_BEHAVIOR`, +`GLFW_RELEASE_BEHAVIOR_FLUSH` or `GLFW_RELEASE_BEHAVIOR_NONE`.

The one exception is +[GLFW_DOUBLEBUFFER](@ref GLFW_DOUBLEBUFFER_attrib), as this is not provided by +OpenGL ES. + +If you are using version 3.0 or later of OpenGL or OpenGL ES, the +`glGetFramebufferAttachmentParameteriv` function can be used to retrieve the +number of bits for the red, green, blue, alpha, depth and stencil buffer +channels.

This can be set before creation with +the [GLFW_DOUBLEBUFFER](@ref GLFW_DOUBLEBUFFER_hint) window hint. + + +@section buffer_swap Buffer swapping + +GLFW windows are by default double buffered. That means that you have two +rendering buffers; a front buffer and a back buffer. The front buffer is +the one being displayed and the back buffer the one you render to. + +When the entire frame has been rendered, it is time to swap the back and the +front buffers in order to display what has been rendered and begin rendering +a new frame. This is done with @ref glfwSwapBuffers. + +@code +glfwSwapBuffers(window); +@endcode + +Sometimes it can be useful to select when the buffer swap will occur. With the +function @ref glfwSwapInterval it is possible to select the minimum number of +monitor refreshes the driver should wait from the time @ref glfwSwapBuffers was +called before swapping the buffers: + +@code +glfwSwapInterval(1); +@endcode + +If the interval is zero, the swap will take place immediately when @ref +glfwSwapBuffers is called without waiting for a refresh. Otherwise at least +interval retraces will pass between each buffer swap. Using a swap interval of +zero can be useful for benchmarking purposes, when it is not desirable to +measure the time it takes to wait for the vertical retrace. However, a swap +interval of one lets you avoid tearing. + +Note that this may not work on all machines, as some drivers have +user-controlled settings that override any swap interval the application +requests. + +A context that supports either the `WGL_EXT_swap_control_tear` or the +`GLX_EXT_swap_control_tear` extension also accepts _negative_ swap intervals, +which allows the driver to swap immediately even if a frame arrives a little bit +late. This trades the risk of visible tears for greater framerate stability. +You can check for these extensions with @ref glfwExtensionSupported. + +*/ diff --git a/3rdparty/glfw/source/examples/CMakeLists.txt b/3rdparty/glfw/source/examples/CMakeLists.txt new file mode 100644 index 0000000..be8927d --- /dev/null +++ b/3rdparty/glfw/source/examples/CMakeLists.txt @@ -0,0 +1,88 @@ + +link_libraries(glfw) + +include_directories("${GLFW_SOURCE_DIR}/deps") + +if (MATH_LIBRARY) + link_libraries("${MATH_LIBRARY}") +endif() + +# Workaround for the MS CRT deprecating parts of the standard library +if (MSVC OR CMAKE_C_SIMULATE_ID STREQUAL "MSVC") + add_definitions(-D_CRT_SECURE_NO_WARNINGS) +endif() + +if (WIN32) + set(ICON glfw.rc) +elseif (APPLE) + set(ICON glfw.icns) +endif() + +set(GLAD_GL "${GLFW_SOURCE_DIR}/deps/glad/gl.h") +set(GLAD_GLES2 "${GLFW_SOURCE_DIR}/deps/glad/gles2.h") +set(GETOPT "${GLFW_SOURCE_DIR}/deps/getopt.h" + "${GLFW_SOURCE_DIR}/deps/getopt.c") +set(TINYCTHREAD "${GLFW_SOURCE_DIR}/deps/tinycthread.h" + "${GLFW_SOURCE_DIR}/deps/tinycthread.c") + +add_executable(boing WIN32 MACOSX_BUNDLE boing.c ${ICON} ${GLAD_GL}) +add_executable(gears WIN32 MACOSX_BUNDLE gears.c ${ICON} ${GLAD_GL}) +add_executable(heightmap WIN32 MACOSX_BUNDLE heightmap.c ${ICON} ${GLAD_GL}) +add_executable(offscreen offscreen.c ${ICON} ${GLAD_GL}) +add_executable(particles WIN32 MACOSX_BUNDLE particles.c ${ICON} ${TINYCTHREAD} ${GETOPT} ${GLAD_GL}) +add_executable(sharing WIN32 MACOSX_BUNDLE sharing.c ${ICON} ${GLAD_GL}) +add_executable(splitview WIN32 MACOSX_BUNDLE splitview.c ${ICON} ${GLAD_GL}) +add_executable(triangle-opengl WIN32 MACOSX_BUNDLE triangle-opengl.c ${ICON} ${GLAD_GL}) +add_executable(triangle-opengles WIN32 MACOSX_BUNDLE triangle-opengles.c ${ICON} ${GLAD_GLES2}) +add_executable(wave WIN32 MACOSX_BUNDLE wave.c ${ICON} ${GLAD_GL}) +add_executable(windows WIN32 MACOSX_BUNDLE windows.c ${ICON} ${GLAD_GL}) + +target_link_libraries(particles Threads::Threads) +if (RT_LIBRARY) + target_link_libraries(particles "${RT_LIBRARY}") +endif() + +set(GUI_ONLY_BINARIES boing gears heightmap particles sharing splitview + triangle-opengl triangle-opengles wave windows) +set(CONSOLE_BINARIES offscreen) + +set_target_properties(${GUI_ONLY_BINARIES} ${CONSOLE_BINARIES} PROPERTIES + C_STANDARD 99 + FOLDER "GLFW3/Examples") + +if (GLFW_USE_OSMESA) + find_package(OSMesa REQUIRED) + target_compile_definitions(offscreen PRIVATE USE_NATIVE_OSMESA) +endif() + +if (MSVC) + # Tell MSVC to use main instead of WinMain + set_target_properties(${GUI_ONLY_BINARIES} PROPERTIES + LINK_FLAGS "/ENTRY:mainCRTStartup") +elseif (CMAKE_C_SIMULATE_ID STREQUAL "MSVC") + # Tell Clang using MS CRT to use main instead of WinMain + set_target_properties(${GUI_ONLY_BINARIES} PROPERTIES + LINK_FLAGS "-Wl,/entry:mainCRTStartup") +endif() + +if (APPLE) + set_target_properties(boing PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Boing") + set_target_properties(gears PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Gears") + set_target_properties(heightmap PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Heightmap") + set_target_properties(particles PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Particles") + set_target_properties(sharing PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Sharing") + set_target_properties(triangle-opengl PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "OpenGL Triangle") + set_target_properties(triangle-opengles PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "OpenGL ES Triangle") + set_target_properties(splitview PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "SplitView") + set_target_properties(wave PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Wave") + set_target_properties(windows PROPERTIES MACOSX_BUNDLE_BUNDLE_NAME "Windows") + + set_source_files_properties(glfw.icns PROPERTIES + MACOSX_PACKAGE_LOCATION "Resources") + set_target_properties(${GUI_ONLY_BINARIES} PROPERTIES + MACOSX_BUNDLE_SHORT_VERSION_STRING ${GLFW_VERSION} + MACOSX_BUNDLE_LONG_VERSION_STRING ${GLFW_VERSION} + MACOSX_BUNDLE_ICON_FILE glfw.icns + MACOSX_BUNDLE_INFO_PLIST "${GLFW_SOURCE_DIR}/CMake/Info.plist.in") +endif() + diff --git a/3rdparty/glfw/source/examples/boing.c b/3rdparty/glfw/source/examples/boing.c new file mode 100644 index 0000000..ec118a3 --- /dev/null +++ b/3rdparty/glfw/source/examples/boing.c @@ -0,0 +1,680 @@ +/***************************************************************************** + * Title: GLBoing + * Desc: Tribute to Amiga Boing. + * Author: Jim Brooks + * Original Amiga authors were R.J.

The UI can be highly dynamic, there are no construction or + destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, fewer bugs. + - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features. + - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build. + - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori). + You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki. + - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances. + For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI, + where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches. + - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right. + - This codebase is also optimized to yield decent performances with typical "Debug" builds settings. + - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected). + If you get an assert, read the messages and comments around the assert. + - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace. + - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types. + See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that. + However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase. + - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!). + + + HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI + ---------------------------------------------- + - Overwrite all the sources files except for imconfig.h (if you have modified your copy of imconfig.h) + - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over "master". + - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file. + - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes. + If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed + from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will + likely be a comment about it.

The only function that knows about GPU is the draw function that you provide. + Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" + phases of your own application. All rendering information is stored into command-lists that you will retrieve after calling ImGui::Render(). + - Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code. + - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder. + + + HOW A SIMPLE APPLICATION MAY LOOK LIKE + -------------------------------------- + EXHIBIT 1: USING THE EXAMPLE BACKENDS (= imgui_impl_XXX.cpp files from the backends/ folder). + The sub-folders in examples/ contain examples applications following this structure. + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Initialize helper Platform and Renderer backends (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp) + ImGui_ImplWin32_Init(hwnd); + ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext); + + // Application main loop + while (true) + { + // Feed inputs to dear imgui, start new frame + ImGui_ImplDX11_NewFrame(); + ImGui_ImplWin32_NewFrame(); + ImGui::NewFrame(); + + // Any application code here + ImGui::Text("Hello, world!"); + + // Render dear imgui into screen + ImGui::Render(); + ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData()); + g_pSwapChain->Present(1, 0); + } + + // Shutdown + ImGui_ImplDX11_Shutdown(); + ImGui_ImplWin32_Shutdown(); + ImGui::DestroyContext(); + + EXHIBIT 2: IMPLEMENTING CUSTOM BACKEND / CUSTOM ENGINE + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Build and load the texture atlas into a texture + // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer) + int width, height; + unsigned char* pixels = NULL; + io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); + + // At this point you've got the texture data and you need to upload that to your graphic system: + // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'. + // This will be passed back to your via the renderer.

For more advanced uses, you may want to read from: + - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set. + - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used). + - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions. + Please reach out if you think the game vs navigation input sharing could be improved. + - Gamepad: + - Application: Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable. + - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + call io.AddKeyEvent/AddKeyAnalogEvent() with ImGuiKey_Gamepad_XXX keys. + For analog values (0.0f to 1.0f), backend is responsible to handling a dead-zone and rescaling inputs accordingly. + Backend code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.). + - Internally: NewFrame() will automatically fill io.NavInputs[] based on backend's io.AddKeyEvent() + io.AddKeyAnalogEvent() calls. + - BEFORE 1.87, BACKENDS USED TO WRITE DIRECTLY TO io.NavInputs[]. This is going to be obsoleted in the future. Please call io functions instead! + - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://dearimgui.org/controls_sheets + - If you need to share inputs between your game and the Dear ImGui interface, the easiest approach is to go all-or-nothing, + with a buttons combo to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved. + - Mouse: + - PS4/PS5 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback. + - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard. + - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag. + Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements. + When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved. + When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends in examples/ do that. + (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse moving back and forth!) + (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want + to set a boolean to ignore your other external mouse positions until the external source is moved again.) + + + API BREAKING CHANGES + ==================== + + Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix. + Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code. + When you are not sure about an old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files. + You can read releases logs https://github.com/ocornut/imgui/releases for more details. + + - 2022/01/20 (1.87) - inputs: reworded gamepad IO. + - Backend writing to io.NavInputs[] -> backend should call io.AddKeyEvent()/io.AddKeyAnalogEvent() with ImGuiKey_GamepadXXX values. + - 2022/01/19 (1.87) - sliders, drags: removed support for legacy arithmetic operators (+,+-,*,/) when inputing text. This doesn't break any api/code but a feature that used to be accessible by end-users (which seemingly no one used). + - 2022/01/17 (1.87) - inputs: reworked mouse IO. + - Backend writing to io.MousePos -> backend should call io.AddMousePosEvent() + - Backend writing to io.MouseDown[] -> backend should call io.AddMouseButtonEvent() + - Backend writing to io.MouseWheel -> backend should call io.AddMouseWheelEvent() + - Backend writing to io.MouseHoveredViewport -> backend should call io.AddMouseViewportEvent() [Docking branch w/ multi-viewports only] + - 2022/01/10 (1.87) - inputs: reworked keyboard IO. Removed io.KeyMap[], io.KeysDown[] in favor of calling io.AddKeyEvent(). Removed GetKeyIndex(), now unecessary. All IsKeyXXX() functions now take ImGuiKey values. All features are still functional until IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Read Changelog and Release Notes for details. + - IsKeyPressed(MY_NATIVE_KEY_XXX) -> use IsKeyPressed(ImGuiKey_XXX) + - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX) + - Backend writing to io.KeyMap[],io.KeysDown[] -> backend should call io.AddKeyEvent() + - Backend writing to io.KeyCtrl, io.KeyShift.. -> backend should call io.AddKeyEvent() with ImGuiKey_ModXXX values. *IF YOU PULLED CODE BETWEEN 2021/01/10 and 2021/01/27: We used to have a io.AddKeyModsEvent() function which was now replaced by io.AddKeyEvent() with ImGuiKey_ModXXX values.* + - one case won't work with backward compatibility: if your custom backend used ImGuiKey as mock native indices (e.g. "io.KeyMap[ImGuiKey_A] = ImGuiKey_A") because those values are now larger than the legacy KeyDown[] array. Will assert. + - inputs: added ImGuiKey_ModCtrl/ImGuiKey_ModShift/ImGuiKey_ModAlt/ImGuiKey_ModSuper values to submit keyboard modifiers using io.AddKeyEvent(), instead of writing directly to io.KeyCtrl, io.KeyShift, io.KeyAlt, io.KeySuper. + - 2022/01/05 (1.87) - inputs: renamed ImGuiKey_KeyPadEnter to ImGuiKey_KeypadEnter to align with new symbols. Kept redirection enum. + - 2022/01/05 (1.87) - removed io.ImeSetInputScreenPosFn() in favor of more flexible io.SetPlatformImeDataFn(). Removed 'void* io.ImeWindowHandle' in favor of writing to 'void* ImGuiViewport::PlatformHandleRaw'. + - 2022/01/01 (1.87) - commented out redirecting functions/enums names that were marked obsolete in 1.69, 1.70, 1.71, 1.72 (March-July 2019) + - ImGui::SetNextTreeNodeOpen() -> use ImGui::SetNextItemOpen() + - ImGui::GetContentRegionAvailWidth() -> use ImGui::GetContentRegionAvail().x + - ImGui::TreeAdvanceToLabelPos() -> use ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetTreeNodeToLabelSpacing()); + - ImFontAtlas::CustomRect -> use ImFontAtlasCustomRect + - ImGuiColorEditFlags_RGB/HSV/HEX -> use ImGuiColorEditFlags_DisplayRGB/HSV/Hex + - 2021/12/20 (1.86) - backends: removed obsolete Marmalade backend (imgui_impl_marmalade.cpp) + example. Find last supported version at https://github.com/ocornut/imgui/wiki/Bindings + - 2021/11/04 (1.86) - removed CalcListClipping() function. Prefer using ImGuiListClipper which can return non-contiguous ranges. Please open an issue if you think you really need this function. + - 2021/08/23 (1.85) - removed GetWindowContentRegionWidth() function. keep inline redirection helper. can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead for generally 'GetContentRegionAvail().x' is more useful. + - 2021/07/26 (1.84) - commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019): + - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList() + - ImFont::GlyphRangesBuilder -> use ImFontGlyphRangesBuilder + - 2021/05/19 (1.83) - backends: obsoleted direct access to ImDrawCmd::TextureId in favor of calling ImDrawCmd::GetTexID(). + - if you are using official backends from the source tree: you have nothing to do. + - if you have copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID(). + - 2021/03/12 (1.82) - upgraded ImDrawList::AddRect(), AddRectFilled(), PathRect() to use ImDrawFlags instead of ImDrawCornersFlags. + - ImDrawCornerFlags_TopLeft -> use ImDrawFlags_RoundCornersTopLeft + - ImDrawCornerFlags_BotRight -> use ImDrawFlags_RoundCornersBottomRight + - ImDrawCornerFlags_None -> use ImDrawFlags_RoundCornersNone etc. + flags now sanely defaults to 0 instead of 0x0F, consistent with all other flags in the API. + breaking: the default with rounding > 0.0f is now "round all corners" vs old implicit "round no corners": + - rounding == 0.0f + flags == 0 --> meant no rounding --> unchanged (common use) + - rounding > 0.0f + flags != 0 --> meant rounding --> unchanged (common use) + - rounding == 0.0f + flags != 0 --> meant no rounding --> unchanged (unlikely use) + - rounding > 0.0f + flags == 0 --> meant no rounding --> BREAKING (unlikely use): will now round all corners --> use ImDrawFlags_RoundCornersNone or rounding == 0.0f. + this ONLY matters for hard coded use of 0 + rounding > 0.0f. Use of named ImDrawFlags_RoundCornersNone (new) or ImDrawCornerFlags_None (old) are ok. + the old ImDrawCornersFlags used awkward default values of ~0 or 0xF (4 lower bits set) to signify "round all corners" and we sometimes encouraged using them as shortcuts. + legacy path still support use of hard coded ~0 or any value from 0x1 or 0xF. They will behave the same with legacy paths enabled (will assert otherwise). + - 2021/03/11 (1.82) - removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018): + - ImGui::SetScrollHere() -> use ImGui::SetScrollHereY() + - 2021/03/11 (1.82) - clarified that ImDrawList::PathArcTo(), ImDrawList::PathArcToFast() won't render with radius < 0.0f. Previously it sorts of accidentally worked but would generally lead to counter-clockwise paths and have an effect on anti-aliasing. + - 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future. + - 2021/02/22 (1.82) - (*undone in 1.84*) win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'. + - 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed. + - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete). + - removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete). + - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete). + - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags. + - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags. + - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018): + - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit(). + - ImGuiCol_ModalWindowDarkening -> use ImGuiCol_ModalWindowDimBg + - ImGuiInputTextCallback -> use ImGuiTextEditCallback + - ImGuiInputTextCallbackData -> use ImGuiTextEditCallbackData + - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete). + - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added! + - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API. + - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures + - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018): + - io.RenderDrawListsFn pointer -> use ImGui::GetDrawData() value and call the render function of your backend + - ImGui::IsAnyWindowFocused() -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow) + - ImGui::IsAnyWindowHovered() -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + - ImGuiStyleVar_Count_ -> use ImGuiStyleVar_COUNT + - ImGuiMouseCursor_Count_ -> use ImGuiMouseCursor_COUNT + - removed redirecting functions names that were marked obsolete in 1.61 (May 2018): + - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X is your value for decimal_precision. + - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter. + - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed). + - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently). + - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton. + - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory. + - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result. + - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now! + - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar(). + replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags). + worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions: + - if you omitted the 'power' parameter (likely!), you are not affected. + - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct. + - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f. + see https://github.com/ocornut/imgui/issues/3361 for all details. + kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used. + for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`. + - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime. + - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems. + - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79] + - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017. + - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular(). + - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more. + - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead. + - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value. + - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017): + - ShowTestWindow() -> use ShowDemoWindow() + - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow) + - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows) + - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f) + - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing() + - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg + - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding + - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap + - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS + - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was vaguely documented and rarely if ever used). Instead, we added an explicit PrimUnreserve() API. + - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it). + - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency. + - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017): + - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed + - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows) + - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding() + - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f) + - ImFont::Glyph -> use ImFontGlyph + - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function. + if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix. + The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay). + If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you. + - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete). + - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete). + - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71. + - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have + overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering. + This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows. + Please reach out if you are affected. + - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete). + - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c). + - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now. + - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete). + - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete). + - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete). + - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrarily small value! + - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already). + - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead! + - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete). + - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects. + - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags. + - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files. + - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete). + - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h. + If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths. + - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp. + NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED. + Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions. + - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent). + - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete). + - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly). + - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature. + - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency. + - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time. + - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete). + - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.). + old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports. + when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call. + in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function. + - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set. + - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details. + - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more. + If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format. + To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code. + If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them. + - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format", + consistent with other functions. Kept redirection functions (will obsolete). + - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value. + - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch). + - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now. + - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. + - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums. + - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment. + - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display. + - 2018/02/07 (1.60) - reorganized context handling to be more explicit, + - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. + - removed Shutdown() function, as DestroyContext() serve this purpose. + - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance. + - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts. + - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts. + - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths. + - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData. + - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side. + - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete). + - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags + - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame. + - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. + - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete). + - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete). + - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete). + - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete). + - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete). + - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed. + - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up. + Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions. + - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. + - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg. + - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding. + - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows); + - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency. + - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. + - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details. + removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting. + IsItemHoveredRect() --> IsItemHovered(ImGuiHoveredFlags_RectOnly) + IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + IsMouseHoveringWindow() --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior] + - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead! + - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete). + - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete). + - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete). + - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)". + - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)! + - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete). + - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete). + - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency. + - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix. + - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type. + - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely. + - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete). + - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete). + - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton(). + - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu. + - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options. + - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))' + - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse + - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. + - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity. + - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetID() and use it instead of passing string to BeginChild(). + - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it. + - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. + - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully, breakage should be minimal. + - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. + If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. + This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color: + ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); } + If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color. + - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext(). + - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection. + - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen). + - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer. + - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref GitHub issue #337). + - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337) + - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). + - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert. + - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you. + - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. + - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. + - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position. + GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side. + GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out! + - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize + - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project. + - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason + - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure. + you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text. + - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost. + this necessary change will break your rendering function! the fix should be very easy. sorry for that :( + - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest. + - the signature of the io.RenderDrawListsFn handler has changed! + old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) + new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). + parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount' + ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new. + ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'. + - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer. + - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering! + - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade! + - 2015/07/10 (1.43) - changed SameLine() parameters from int to float. + - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete). + - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount. + - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence + - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely used. Sorry! + - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete). + - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete). + - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons. + - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened. + - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same). + - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50. + - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API + - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive. + - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead. + - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect().

In this mode, it declares a +// single public symbol, STB_TexteditState, which encapsulates the current +// state of a text widget (except for the string, which you will store +// separately). +// +// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a +// primitive type that defines a single character (e.g. char, wchar_t, etc). +// +// To save space or increase undo-ability, you can optionally define the +// following things that are used by the undo system: +// +// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// If you don't define these, they are set to permissive types and +// moderate sizes. The undo system does no memory allocations, so +// it grows STB_TexteditState by the worst-case storage which is (in bytes): +// +// [4 + 3 * sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATE_COUNT +// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHAR_COUNT +// +// +// Implementation mode: +// +// If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it +// will compile the implementation of the text edit widget, depending +// on a large number of symbols which must be defined before the include. +// +// The implementation is defined only as static functions. You will then +// need to provide your own APIs in the same file which will access the +// static functions. +// +// The basic concept is that you provide a "string" object which +// behaves like an array of characters. stb_textedit uses indices to +// refer to positions in the string, implicitly representing positions +// in the displayed textedit. This is true for both plain text and +// rich text; even with rich text stb_truetype interacts with your +// code as if there was an array of all the displayed characters. +// +// Symbols that must be the same in header-file and implementation mode: +// +// STB_TEXTEDIT_CHARTYPE the character type +// STB_TEXTEDIT_POSITIONTYPE small type that is a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// Symbols you must define for implementation mode: +// +// STB_TEXTEDIT_STRING the type of object representing a string being edited, +// typically this is a wrapper object with other data you need +// +// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1)) +// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters +// starting from character #n (see discussion below) +// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character +// to the xpos of the i+1'th char for a line of characters +// starting at character #n (i.e. accounts for kerning +// with previous char) +// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character +// (return type is int, -1 means not valid to insert) +// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based +// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize +// as manually wordwrapping for end-of-line positioning +// +// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i +// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*) +// +// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key +// +// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left +// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right +// STB_TEXTEDIT_K_UP keyboard input to move cursor up +// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down +// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page +// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page +// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME +// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END +// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME +// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END +// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor +// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor +// STB_TEXTEDIT_K_UNDO keyboard input to perform undo +// STB_TEXTEDIT_K_REDO keyboard input to perform redo +// +// Optional: +// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode +// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'), +// required for default WORDLEFT/WORDRIGHT handlers +// STB_TEXTEDIT_MOVEWORDLEFT(obj,i) custom handler for WORDLEFT, returns index to move cursor to +// STB_TEXTEDIT_MOVEWORDRIGHT(obj,i) custom handler for WORDRIGHT, returns index to move cursor to +// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT +// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT +// STB_TEXTEDIT_K_LINESTART2 secondary keyboard input to move cursor to start of line +// STB_TEXTEDIT_K_LINEEND2 secondary keyboard input to move cursor to end of line +// STB_TEXTEDIT_K_TEXTSTART2 secondary keyboard input to move cursor to start of text +// STB_TEXTEDIT_K_TEXTEND2 secondary keyboard input to move cursor to end of text +// +// Keyboard input must be encoded as a single integer value; e.g. a character code +// and some bitflags that represent shift states. to simplify the interface, SHIFT must +// be a bitflag, so we can test the shifted state of cursor movements to allow selection, +// i.e. (STB_TEXTEDIT_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow. +// +// You can encode other things, such as CONTROL or ALT, in additional bits, and +// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT. For example, +// my Windows implementations add an additional CONTROL bit, and an additional KEYDOWN +// bit. Then all of the STB_TEXTEDIT_K_ values bitwise-or in the KEYDOWN bit, +// and I pass both WM_KEYDOWN and WM_CHAR events to the "key" function in the +// API below. The control keys will only match WM_KEYDOWN events because of the +// keydown bit I add, and STB_TEXTEDIT_KEYTOTEXT only tests for the KEYDOWN +// bit so it only decodes WM_CHAR events. +// +// STB_TEXTEDIT_LAYOUTROW returns information about the shape of one displayed +// row of characters assuming they start on the i'th character--the width and +// the height and the number of characters consumed. This allows this library +// to traverse the entire layout incrementally. You need to compute word-wrapping +// here. +// +// Each textfield keeps its own insert mode state, which is not how normal +// applications work.

STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to +// anything other type you wante before including. +// +// +// When rendering, you can read the cursor position and selection state from +// the STB_TexteditState. +// +// +// Notes: +// +// This is designed to be usable in IMGUI, so it allows for the possibility of +// running in an IMGUI that has NOT cached the multi-line layout. For this +// reason, it provides an interface that is compatible with computing the +// layout incrementally--we try to make sure we make as few passes through +// as possible. (For example, to locate the mouse pointer in the text, we +// could define functions that return the X and Y positions of characters +// and binary search Y and then X, but if we're doing dynamic layout this +// will run the layout algorithm many times, so instead we manually search +// forward in one pass. Similar logic applies to e.g. up-arrow and +// down-arrow movement.) +// +// If it's run in a widget that *has* cached the layout, then this is less +// efficient, but it's not horrible on modern computers.

Thus, anti-aliasing of intersecting shapes may look wrong. If +// this turns out to be a problem, you can re-enable the old rasterizer with +// #define STBTT_RASTERIZER_VERSION 1 +// which will incur about a 15% speed hit. +// +// ADDITIONAL DOCUMENTATION +// +// Immediately after this block comment are a series of sample programs. +// +// After the sample programs is the "header file" section. This section +// includes documentation for each API function. +// +// Some important concepts to understand to use this library: +// +// Codepoint +// Characters are defined by unicode codepoints, e.g. 65 is +// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is +// the hiragana for "ma". +// +// Glyph +// A visual character shape (every codepoint is rendered as +// some glyph) +// +// Glyph index +// A font-specific integer ID representing a glyph +// +// Baseline +// Glyph shapes are defined relative to a baseline, which is the +// bottom of uppercase characters. Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// DETAILED USAGE: +// +// Scale: +// Select how high you want the font to be, in points or pixels. +// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute +// a scale factor SF that will be used by all other functions. +// +// Baseline: +// You need to select a y-coordinate that is the baseline of where +// your text will appear. Call GetFontBoundingBox to get the baseline-relative +// bounding box for all characters. SF*-y0 will be the distance in pixels +// that the worst-case character could extend above the baseline, so if +// you want the top edge of characters to appear at the top of the +// screen where y=0, then you would set the baseline to SF*-y0. +// +// Current point: +// Set the current point where the first character will appear. The +// first character could extend left of the current point; this is font +// dependent. You can either choose a current point that is the leftmost +// point and hope, or add some padding, or check the bounding box or +// left-side-bearing of the first character to be displayed and set +// the current point based on that. +// +// Displaying a character: +// Compute the bounding box of the character. It will contain signed values +// relative to .
