Struct PlatformWindow 

pub struct PlatformWindow { /* private fields */ }

A platform window wrapping a winit window, wgpu surface, renderer, and AccessKit adapter for screen reader support.

Implementations

impl PlatformWindow

pub async fn new_with_a11y(window: Window, event_loop: &ActiveEventLoop) -> Self

Create a new platform window from a winit window. The event_loop parameter is needed for the AccessKit adapter.

pub async fn new(window: Window) -> Self

Create a platform window without AccessKit (for contexts without ActiveEventLoop).

pub fn window(&self) -> &Window

pub fn window_arc(&self) -> Arc<Window>

Get a clonable Arc reference to the underlying winit window. Used by teksilo_platform::create_title_bar_host and other components that need shared ownership of the window.

pub fn renderer(&self) -> &Renderer

pub fn renderer_mut(&mut self) -> &mut Renderer

pub fn scale_factor(&self) -> f64

pub fn set_scale_factor(&mut self, factor: f64)

pub fn resize(&mut self, new_size: PhysicalSize<u32>)

Resize the surface.

pub fn surface_size(&self) -> (u32, u32)

Get current surface dimensions.

pub fn reconfigure_surface(&mut self)

Reconfigure the surface with the current config. Use after a Lost or Outdated surface error.

pub fn render_frame( &mut self, frame: &RenderFrame, clear_color: [f32; 4], ) -> FrameOutcome

Render a frame to the surface.

pub fn capture_offscreen( &mut self, frame: &RenderFrame, clear_color: [f32; 4], crop: Option<Rect>, ) -> (Vec<u8>, u32, u32)

Render frame into an offscreen texture and read it back as tightly-packed RGBA8 bytes, returning (rgba, width, height).

Used by the debug-only automation bridge to capture a live window without going through the swapchain — the surface texture is configured RENDER_ATTACHMENT only (no COPY_SRC), so it can’t be read back directly. The offscreen texture uses the window’s own surface format so it matches the renderer’s pipelines; a BGRA readback is swizzled to RGBA here so the output is always RGBA. With crop = Some(rect) (physical pixels, clamped to the surface) only that sub-rectangle is returned. Returns an empty (vec, 0, 0) if the crop is fully outside the surface.

Note: a native WebView subview composites on top of the wgpu surface and is invisible to this readback (a transparent hole).

pub fn request_redraw(&self)

pub fn update_accessibility(&mut self, update: TreeUpdate)

Push an AccessKit TreeUpdate to the adapter (called after layout).

pub fn process_accessibility_event(&mut self, event: &WindowEvent)

Forward a winit WindowEvent to the AccessKit adapter.

pub fn drain_accessibility_actions(&self) -> Vec<ActionRequest>

Drain any pending AccessKit action requests from the adapter.
