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

Helper: ImVec2i (2D vector, integer)

Helper for key->value storage (container sorted by key)

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

Baked data for a ImFont at a given size.

Storage for one type registered in the .ini file

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

Coordinates of a rectangle within a texture.

Forward declarations: ImDrawList, ImFontAtlas layer

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

Output of ImFontAtlas::GetCustomRect() when using custom rectangles.

Stacked storage data for BeginGroup()/EndGroup()

Routing table entry (sizeof() == 16 bytes)

Temporary clipper data, buffers shared/reused between instances

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

Helper for key->value storage (pair)

Style variable information (e.g. to access style variables from an enum)

Storage for a tab bar

Storage for TableAngledHeadersRow()

sizeof() ~ 16

Storage for one column of a table

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

Storage for GetTypingSelectRequest() (aimed to be public)

Console variable name hashes

============================= Global State =============================

Precomputed HUD element hashes

Utilities (other types which are not forwarded declared are: ImBitArray<>, ImSpan<>, ImSpanAllocator<>, ImStableVector<>, ImPool<>, ImChunkStream<>)

[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)

ImDrawList/ImFontAtlas

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)

Helpers: High-level text functions (DO NOT USE!!! THIS IS A MINIMAL SUBSET OF LARGER UPCOMING CHANGES)

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

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

Data shared between all ImDrawList instances

Flags for ImFontAtlas build

Internal storage for incrementally packing and building a ImFontAtlas

Opaque storage for building a ImFontAtlas

Data available to potential texture post-processing functions

Font flags (in future versions as we redesign font loading API, this will become more important and better documented. for now please consider this as

Configuration data when adding a font or merging fonts

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

Helper to build glyph ranges from text/string data

Hooks and storage for a given font backend. This structure is likely to evolve as we add support for incremental atlas updates. Conceptually this coul

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