imgui.internal (C++)

Dear ImGui’s internal API (imgui_internal.h): the functions and structures that the widgets are built with.

The C++ API of Dear ImGui as it is bound to Python: the entries of the module imgui_bundle.imgui.internal, in the same order, with their C++ signatures and the headers’ comments. From the stubs: the functions excluded from the bindings, the typedefs and the macros are absent.

`WindowDockStyleCol` (enum)¶

List of colors that are stored at the time of Begin() into Docked Windows.
We currently store the packed colors in a simple array window->DockStyle.Colors[].
A better solution may involve appending into a log of colors in ImGuiContext + store offsets into those arrays in ImGuiWindow, but it would be more complex as we’d need to double-buffer both as e.g. drop target may refer to window from last frame.

Table support + internal API¶

`TableColumn` (struct)¶

[Internal] sizeof() ~ 120
We use the terminology “Enabled” to refer to a column that is not Hidden by user/api.
We use the terminology “Clipped” to refer to a column that is out of sight because of scrolling/clipping.
This is in contrast with some user-facing api such as IsItemVisible() / IsRectVisible() which use “Visible” to mean “not clipped”.

No guarantee of forward compatibility here!¶

Windows
We should always have a CurrentWindow in the stack (there is an implicit “Debug” window)
If this ever crashes because g.CurrentWindow is None, it means that either:

You are calling ImGui functions after ImGui::EndFrame()/ImGui::Render() and before the next ImGui::NewFrame(), which is also illegal.

[EXPERIMENTAL] Low-Level: Key/Input Ownership¶

The idea is that instead of “eating” a given input, we can link to an owner id.
Ownership is most often claimed as a result of reacting to a press/down event (but occasionally may be claimed ahead).
Input queries can then read input by specifying ImGuiKeyOwner_Any (== 0), ImGuiKeyOwner_NoOwner (== -1) or a custom ID.
Legacy input queries (without specifying an owner or _Any or _None) are equivalent to using ImGuiKeyOwner_Any (== 0).
Input ownership is automatically released on the frame after a key is released. Therefore:
- for ownership registration happening as a result of a down/press event, the SetKeyOwner() call may be done once (common case).
- for ownership registration happening ahead of a down/press event, the SetKeyOwner() call needs to be made every frame (happens if e.g. claiming ownership on hover).
SetItemKeyOwner() is a shortcut for common simple case. A custom widget will probably want to call SetKeyOwner() multiple times directly based on its interaction state.
This is marked experimental because not all widgets are fully honoring the Set/Test idioms. We will need to move forward step by step.
Please open a GitHub Issue to submit your usage scenario or if there’s a use case you need solved.

`ImGui::GetKeyOwner`¶

IMGUI_API ImGuiID GetKeyOwner(ImGuiKey key);

`ImGui::SetKeyOwner`¶

IMGUI_API void SetKeyOwner(ImGuiKey key, ImGuiID owner_id, ImGuiInputFlags flags = 0);

`ImGui::SetKeyOwnersForKeyChord`¶

`ImGui::GetKeyOwnerData`¶

inline ImGuiKeyOwnerData* GetKeyOwnerData(ImGuiContext* ctx, ImGuiKey key);

(private API)

`ImGui::IsKeyDown`¶

IMGUI_API bool IsKeyDown(ImGuiKey key, ImGuiID owner_id);

[EXPERIMENTAL] High-Level: Input Access functions w/ support for Key/Input Ownership

Important: legacy IsKeyPressed(ImGuiKey, bool repeat=True) DEFAULTS to repeat, new IsKeyPressed() requires EXPLICIT ImGuiInputFlags_Repeat flag.
Expected to be later promoted to public API, the prototypes are designed to replace existing ones (since owner_id can default to Any == 0)
Specifying a value for ‘ImGuiID owner’ will test that EITHER the key is NOT owned (UNLESS locked), EITHER the key is owned by ‘owner’.
Legacy functions use ImGuiKeyOwner_Any meaning that they typically ignore ownership, unless a call to SetKeyOwner() explicitly used ImGuiInputFlags_LockThisFrame or ImGuiInputFlags_LockUntilRelease.
Binding generators may want to ignore those for now, or suffix them with Ex() until we decide if this gets moved into public API.

`ImGui::IsKeyPressed`¶

IMGUI_API bool IsKeyPressed(ImGuiKey key, ImGuiInputFlags flags, ImGuiID owner_id = 0);

Important: when transitioning from old to new IsKeyPressed(): old API has “bool repeat = True”, so would default to repeat. New API requires explicit ImGuiInputFlags_Repeat.

`ImGui::IsKeyReleased`¶

IMGUI_API bool IsMouseDoubleClicked(ImGuiMouseButton button, ImGuiID owner_id);

Shortcut Testing & Routing¶

Set Shortcut() and SetNextItemShortcut() in imgui.h
When a policy (except for ImGuiInputFlags_RouteAlways ) is set, Shortcut() will register itself with SetShortcutRouting(), allowing the system to decide where to route the input among other route-aware calls. ( using ImGuiInputFlags_RouteAlways is roughly equivalent to calling IsKeyChordPressed(key) and bypassing route registration and check)
When using one of the routing option:
- The default route is ImGuiInputFlags_RouteFocused (accept inputs if window is in focus stack. Deep-most focused window takes inputs. ActiveId takes inputs over deep-most focused window.)
- Routes are requested given a chord (key + modifiers) and a routing policy.
- Routes are resolved during NewFrame(): if keyboard modifiers are matching current ones: SetKeyOwner() is called + route is granted for the frame.
- Each route may be granted to a single owner. When multiple requests are made we have policies to select the winning route (e.g. deep most window).
- Multiple read sites may use the same owner id can all access the granted route.
- When owner_id is 0 we use the current Focus Scope ID as a owner ID in order to identify our location.
You can chain two unrelated windows in the focus stack using SetWindowParentWindowForFocusRoute() e.g. if you have a tool window associated to a document, and you want document shortcuts to run when the tool is focused.

`ImGui::DockBuilderDockWindow`¶

IMGUI_API void DockBuilderDockWindow(const char* window_name, ImGuiID node_id);

Docking - Builder function needs to be generally called before the node is used/submitted.

The DockBuilderXXX functions are designed to eventually become a public API, but it is too early to expose it and guarantee stability.
Do not hold on ImGuiDockNode* pointers! They may be invalidated by any split/merge/remove operation and every frame.
To create a DockSpace() node, make sure to set the ImGuiDockNodeFlags_DockSpace flag when calling DockBuilderAddNode().
You can create dockspace nodes (attached to a window) or floating nodes (carry its own window) with this API.
DockBuilderSplitNode() create 2 child nodes within 1 node. The initial node becomes a parent node.
If you intend to split the node immediately after creation using DockBuilderSplitNode(), make sure to call DockBuilderSetNodeSize() beforehand. If you don’t, the resulting split sizes may not be reliable.
Call DockBuilderFinish() after you are done.

[EXPERIMENTAL] Focus Scope¶

This is generally used to identify a unique input location (for e.g. a selection set)
There is one per window (automatically set in Begin), but:

Selection patterns generally need to react (e.g. clear a selection) when landing on one item of the set.
So in order to identify a set multiple lists in same window may each need a focus scope.
If you imagine an hypothetical BeginSelectionGroup()/EndSelectionGroup() api, it would likely call PushFocusScope()/EndFocusScope()
Shortcut routing also use focus scope as a default location identifier if an owner is not provided.
We don’t use the ID Stack for this as it is common to want them separate.

Obsolete functions¶

ImFontLoader

`ImFontLoader` (struct)¶

Hooks and storage for a given font backend.
This structure is likely to evolve as we add support for incremental atlas updates.
Conceptually this could be public, but API is still going to be evolve.

Member
`const char* Name;`	(const)
`size_t FontBakedSrcLoaderDataSize;`

`ImFontLoader::ImFontLoader`¶

ImFontLoader();

ImFontAtlas internal API¶

`ImGui::ImFontAtlasRectId_GetIndex`¶

inline int ImFontAtlasRectId_GetIndex(ImFontAtlasRectId id);

(private API)

Helpers: ImTextureRef ==/!= operators provided as convenience (note that _TexID and _TexData are never set simultaneously)
Refer to ImFontAtlasPackGetRect() to better understand how this works.

`ImGui::ImFontAtlasRectId_GetGeneration`¶

inline unsigned int ImFontAtlasRectId_GetGeneration(ImFontAtlasRectId id);

(private API)

`ImGui::ImFontAtlasRectId_Make`¶

inline ImFontAtlasRectId ImFontAtlasRectId_Make(int index_idx, int gen_idx);

(private API)

`ImFontAtlasRectEntry` (struct)¶

Packed rectangle lookup entry (we need an indirection to allow removing/reordering rectangles)
User are returned ImFontAtlasRectId values which are meant to be persistent.
We handle this with an indirection. While Rects[] may be in theory shuffled, compacted etc., RectsIndex[] cannot it is keyed by ImFontAtlasRectId.
RectsIndex[] is used both as an index into Rects[] and an index into itself. This is basically a free-list. See ImFontAtlasBuildAllocRectIndexEntry() code.
Having this also makes it easier to e.g. sort rectangles during repack.
