ImGui の API

https://github.com/ousttrue/limgui

ようやく FFI の整備ができたので、ImGui の API 調査に進む

DockingBuilder

imgui_internal.h に一連の Docking 向けの API がある。

PossiblyAShrub/dock_builder_example.cpp

変数を流用していてわかりにくいのだが、おそらく下記のような感じだと思う。

+----+----+
|    |    |
|Left|----|
|    |Down|
+----+----+
auto root = ImGui::DockBuilderAddNode(dockspace_id, dockspace_flags | ImGuiDockNodeFlags_DockSpace);
                                                                         // 返り値と同じ Left  // 反対側 Right
ImGuiID right;
auto left = ImGui::DockBuilderSplitNode(root, ImGuiDir_Left, 0.2f, nullptr, &right);
                                                                         // 返り値と同じ Down  // 反対側 Up
ImGuiID up;
auto down = ImGui::DockBuilderSplitNode(right, ImGuiDir_Down, 0.25f, nullptr, &up);

Tree

libclang のパース結果の CXCursor のツリー

Table

glTF を表示してみた。さくさく書けてよさそう。
