Not meaningful is parent window can vertically scroll. -// - outer_size.y = 0.0f -> Bottom-align, consistent with BeginChild(). Not recommended unless table is last item in parent window. -// - outer_size.y > 0.0f -> Set Exact height. Recommended when using Scrolling on any axis. -//----------------------------------------------------------------------------- -// Outer size is also affected by the NoHostExtendX/NoHostExtendY flags. -// Important to that note how the two flags have slightly different behaviors! -// - ImGuiTableFlags_NoHostExtendX -> Make outer width auto-fit to columns (overriding outer_size.x value). Only available when ScrollX/ScrollY are disabled and Stretch columns are not used. -// - ImGuiTableFlags_NoHostExtendY -> Make outer height stop exactly at outer_size.y (prevent auto-extending table past the limit). Only available when ScrollX/ScrollY is disabled. Data below the limit will be clipped and not visible. -// In theory ImGuiTableFlags_NoHostExtendY could be the default and any non-scrolling tables with outer_size.y != 0.0f would use exact height. -// This would be consistent but perhaps less useful and more confusing (as vertically clipped items are not easily noticeable) -//----------------------------------------------------------------------------- -// About 'inner_width': -// With ScrollX disabled: -// - inner_width -> *ignored* -// With ScrollX enabled: -// - inner_width < 0.0f -> *illegal* fit in known width (right align from outer_size.x) <-- weird -// - inner_width = 0.0f -> fit in outer_width: Fixed size columns will take space they need (if avail, otherwise shrink down), Stretch columns becomes Fixed columns. -// - inner_width > 0.0f -> override scrolling width, generally to be larger than outer_size.x. Fixed column take space they need (if avail, otherwise shrink down), Stretch columns share remaining space! -//----------------------------------------------------------------------------- -// Details: -// - If you want to use Stretch columns with ScrollX, you generally need to specify 'inner_width' otherwise the concept -// of "available space" doesn't make sense. -// - Even if not really useful, we allow 'inner_width < outer_size.x' for consistency and to facilitate understanding -// of what the value does. -//----------------------------------------------------------------------------- - -//----------------------------------------------------------------------------- -// COLUMNS SIZING POLICIES -//----------------------------------------------------------------------------- -// About overriding column sizing policy and width/weight with TableSetupColumn(): -// We use a default parameter of 'init_width_or_weight == -1'. -// - with ImGuiTableColumnFlags_WidthFixed, init_width <= 0 (default) --> width is automatic -// - with ImGuiTableColumnFlags_WidthFixed, init_width > 0 (explicit) --> width is custom -// - with ImGuiTableColumnFlags_WidthStretch, init_weight <= 0 (default) --> weight is 1.0f -// - with ImGuiTableColumnFlags_WidthStretch, init_weight > 0 (explicit) --> weight is custom -// Widths are specified _without_ CellPadding.

Otherwise, you may skip submitting the contents of a cell/column, BUT ONLY if you know -// it is not going to contribute to row height. -// In many situations, you may skip submitting contents for every column but one (e.g. the first one). -// - Case A: column is not hidden by user, and at least partially in sight (most common case). -// - Case B: column is clipped / out of sight (because of scrolling or parent ClipRect): TableNextColumn() return false as a hint but we still allow layout output. -// - Case C: column is hidden explicitly by the user (e.g. via the context menu, or _DefaultHide column flag, etc.). -// -// [A] [B] [C] -// TableNextColumn(): true false false -> [userland] when TableNextColumn() / TableSetColumnIndex() return false, user can skip submitting items but only if the column doesn't contribute to row height. -// SkipItems: false false true -> [internal] when SkipItems is true, most widgets will early out if submitted, resulting is no layout output. -// ClipRect: normal zero-width zero-width -> [internal] when ClipRect is zero, ItemAdd() will return false and most widgets will early out mid-way. -// ImDrawList output: normal dummy dummy -> [internal] when using the dummy channel, ImDrawList submissions (if any) will be wasted (because cliprect is zero-width anyway). -// -// - We need to distinguish those cases because non-hidden columns that are clipped outside of scrolling bounds should still contribute their height to the row. -// However, in the majority of cases, the contribution to row height is the same for all columns, or the tallest cells are known by the programmer. -//----------------------------------------------------------------------------- -// About clipping/culling of whole Tables: -// - Scrolling tables with a known outer size can be clipped earlier as BeginTable() will return false. -//----------------------------------------------------------------------------- - -//----------------------------------------------------------------------------- -// [SECTION] Header mess -//----------------------------------------------------------------------------- - -#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) -#define _CRT_SECURE_NO_WARNINGS -#endif - -#include "imgui.h" -#ifndef IMGUI_DISABLE - -#ifndef IMGUI_DEFINE_MATH_OPERATORS -#define IMGUI_DEFINE_MATH_OPERATORS -#endif -#include "imgui_internal.h" - -// System includes -#if defined(_MSC_VER) && _MSC_VER <= 1500 // MSVC 2008 or earlier -#include <stddef.h> // intptr_t -#else -#include <stdint.h> // intptr_t -#endif - -// Visual Studio warnings -#ifdef _MSC_VER -#pragma warning (disable: 4127) // condition expression is constant -#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen -#if defined(_MSC_VER) && _MSC_VER >= 1922 // MSVC 2019 16.2 or later -#pragma warning (disable: 5054) // operator '|': deprecated between enumerations of different types -#endif -#pragma warning (disable: 26451) // [Static Analyzer] Arithmetic overflow : Using operator 'xxx' on a 4 byte value and then casting the result to a 8 byte value.
