ImVec4: 4D vector used to store clipping rectangles, colors etc. [Compile-time configurable type]

Emulates std::optional<int> using the sentinel value `INVALID_INDEX`.

Helper: ImVec2ih (2D vector, half-size integer, for long-term packed storage)

Simplified structure to mimic a Document model

Opaque interface to a font builder (stb_truetype or FreeType).

Helper to build glyph ranges from text/string data

Storage of stack sizes for debugging/asserting

Temporary storage for one window (that's the data which in theory we could ditch at the end of the frame, in practice we currently keep it for each wi

Forward declarations

Temporary storage to output draw commands out of order, used by ImDrawListSplitter and ImDrawList::ChannelsSplit()

All draw command lists required to render the frame + pos/size coordinates to use for the projection matrix.

Helper to build a ImDrawData instance

Temporary clipper data, buffers shared/reused between instances

Storage data for a single column for legacy Columns() api

Stacked style modifier, backup of modified data so we can restore it

Storage for a tab bar

Storage for a table

sizeof() ~ 12

Temporary storage for one table (one per table in the stack), shared between tables.

Storage for a column .ini settings

Expose a few Borders related flags interactively

Simplified one-liner Combo() using an accessor function

[Internal] For use by ImDrawList

A single draw command within a parent ImDrawList (generally maps to 1 GPU draw call, unless it is a callback)

An axis-aligned rectangle (2 points)

Flags for ImDrawList functions (Legacy: bit 0 must always correspond to ImDrawFlags_Closed to be backward compatible with old API using a bool. Bits 1

Flags for ImDrawList instance. Those are set automatically by ImGui:: functions from ImGuiIO settings, and generally not manipulated directly. It is h

A single draw command list (generally one per window, conceptually you may see this as a dynamic "mesh" builder)

Data shared among multiple draw lists (typically owned by parent ImGui context, but you may create one yourself)

Helper to split a draw list into different layers which can be drawn into out of order, then flattened back.

A single vertex (pos + uv + col = 20 bytes by default. Override layout with IMGUI_OVERRIDE_DRAWVERT_STRUCT_LAYOUT)

Runtime data for a single font within a parent ImFontAtlas

See ImFontAtlas::AddCustomRectXXX functions.

Flags for ImFontAtlas build

Temporary data for one destination ImFont* (multiple source fonts can be merged into one destination ImFont)

Temporary data for one source font (multiple source fonts can be merged into one destination ImFont) (C++03 doesn't allow instancing ImVector<> with f

Runtime data for multiple fonts, bake multiple fonts into a single texture, TTF/OTF font loader

This structure is likely to evolve as we add support for incremental atlas updates

Configuration data when adding a font or merging fonts

A single font glyph (code point + coordinates within in ImFontAtlas + offset)

X/Y enums are fixed to 0/1 so they may be used to index ImVec2

Backend capabilities flags stored in io.BackendFlags. Set by imgui_impl_xxx or custom backend.

Extend ImGuiButtonFlags_

Flags for InvisibleButton() [extended in imgui_internal.h]

Enumeration for PushStyleColor() / PopStyleColor()

Flags for ColorEdit3() / ColorEdit4() / ColorPicker3() / ColorPicker4() / ColorButton()

Data shared between all ImDrawList instances

Extend ImGuiComboFlags_

Flags for ImGui::BeginCombo()

Enumeration for ImGui::SetWindow***(), SetNextWindow***(), SetNextItem***() functions Represent a condition. Important: Treat as a regular enum! Do NO

Configuration flags stored in io.ConfigFlags. Set by user/application.

Helper functions to create a color that can be converted to either u32 or float4 (*OBSOLETE* please avoid using)

Stacked color modifier, backup of modified data so we can restore it

Main Dear ImGui context

Hook for extensions like ImGuiTestEngine

Extend ImGuiDataType_

A primary data type

A cardinal direction

Flags for ImGui::BeginDragDropSource(), ImGui::AcceptDragDropPayload()
