Description

Platform-agnostic interface for ImGui backend implementations.

Concrete backends (e.g., GLFW+OpenGL, SDL+Vulkan) implement this interface to provide platform-specific initialization, frame setup, and rendering.

Public Member Functions

newFrame()

virtual void helios::ext::imgui::ImGuiBackend::newFrame ()

Prepares ImGui for a new frame.

Must be called at the beginning of each frame before any ImGui calls. Typically invokes platform-specific `NewFrame()` implementations.

Definition at line 36 of file ImGuiBackend.ixx.

renderDrawData()

virtual void helios::ext::imgui::ImGuiBackend::renderDrawData (ImDrawData * drawData)

Renders ImGui draw data to the screen.

Called after `ImGui::Render()` to submit draw commands to the GPU.

Parameters

drawData

Pointer to ImGui draw data (typically from `ImGui::GetDrawData()`).
