}

Provides a platform window for the engine to render into.

The engine doesn’t know about winit, SDL, or any specific windowing library. This trait abstracts window creation, event polling, and surface queries.

Required Methods

fn create(native_loop: &dyn Any, config: &WindowConfig) -> Self

where Self: Sized,

Creates the window.

The native_loop parameter is an opaque handle to the native event loop. The implementation must downcast it to the correct type. For winit: native_loop.downcast_ref::<winit::event_loop::ActiveEventLoop>().

fn request_redraw(&self)

Polls for window events and returns them as an iterator of raw event types.

fn inner_size(&self) -> (u32, u32)

Returns the current inner size of the window in physical pixels.

fn scale_factor(&self) -> f64

Returns the current DPI scaling factor for the window.

fn as_khora_window(&self) -> &dyn KhoraWindow

Returns a reference to the window as a dyn KhoraWindow for use by the engine and agents.

fn translate_event(&self, raw_event: &dyn Any) -> Option<InputEvent>

Translates a raw window event (e.g., winit::event::Event) into an engine-agnostic InputEvent that can be forwarded to game logic.

fn clone_raw_window_arc(&self) -> Arc<dyn Any + Send + Sync>

Clones a long-lived handle to the raw native window as an opaque Arc<dyn Any>. Used by the winit runner to insert the underlying Arc<winit::window::Window> into the service registry so that editor hooks (e.g., overlay begin_frame) can retrieve it without the SDK leaking winit types into application code.
