4D vector (often used to store floating-point colors)

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)

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

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

Storage for a tab bar

Data structures

Backup DX state that will be modified to restore it afterwards (unfortunately this is very ugly looking and verbose. Close your eyes!)

Expose a few Borders related flags interactively

Using the format string to display a name instead of an integer. Here we completely omit '%d' from the format string, so it'll only display a name. Th

[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. Those are set automatically by ImGui:: functions from ImGuiIO settings, and generally not manipulated directly. It is however po

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 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.

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

Flags for ImGui::BeginCombo()

Main configuration and I/O between your application and ImGui

Flags for ImGui::InputText()

Stacked storage data for BeginGroup()/EndGroup()

Transient per-window flags, reset at the beginning of the frame. For child window, inherited from parent on first Begin(). This is going to be exposed

Storage for LastItem data

To test io.KeyMods (which is a combination of individual fields io.KeyCtrl, io.KeyShift, io.KeyAlt set by user/backend)

User fill ImGuiIO.KeyMap[] array with indices into the ImGuiIO.KeysDown[512] array

Backup and restore IsItemHovered() internal data

Result of a gamepad/keyboard directional navigation move query result

Identify a mouse button. Those values are guaranteed to be stable and we frequently use 0/1 directly. Named enums provided for convenience.

Enumeration for GetMouseCursor() User code may request backend to display given cursor by calling SetMouseCursor(), which is why we have some cursors
