// dear imgui: Renderer + Platform Backend for Allegro 5
|
|
// (Info: Allegro 5 is a cross-platform general purpose library for handling windows, inputs, graphics, etc.)
|
|
|
|
// Implemented features:
|
|
// [X] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as texture identifier. Read the FAQ about ImTextureID/ImTextureRef!
|
|
// [X] Renderer: Texture updates support for dynamic font atlas (ImGuiBackendFlags_RendererHasTextures).
|
|
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy ALLEGRO_KEY_* values are obsolete since 1.87 and not supported since 1.91.5]
|
|
// [X] Platform: Clipboard support (from Allegro 5.1.12).
|
|
// [X] Platform: Mouse cursor shape and visibility (ImGuiBackendFlags_HasMouseCursors). Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
|
|
// Missing features or Issues:
|
|
// [ ] Renderer: The renderer is suboptimal as we need to unindex our buffers and convert vertices manually.
|
|
// [ ] Platform: Missing gamepad support.
|
|
|
|
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
|
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
|
