Expand description

A PlatformWindow abstracts away the differents kinds of platform windows that might be used in a servoshell execution. This currently includes headed (winit) and headless windows.

Required Methods§

Source

fn id(&self) -> ServoShellWindowId

Source

fn screen_geometry(&self) -> ScreenGeometry

Source

fn device_hidpi_scale_factor( &self, ) -> Scale<f32, DeviceIndependentPixel, DevicePixel>

Source

fn hidpi_scale_factor(&self) -> Scale<f32, DeviceIndependentPixel, DevicePixel>

Source

fn get_fullscreen(&self) -> bool

Source

fn request_repaint(&self, _: &ServoShellWindow)

Request that the window redraw itself. It is up to the window to do this once the windowing system is ready. If this is a headless window, the redraw will happen immediately.

Source

fn request_resize( &self, webview: &WebView, outer_size: DeviceIntSize, ) -> Option<DeviceIntSize>

Request a new outer size for the window, including external decorations. This should be the same as window.outerWidth and `window.outerHeight``

Source

fn new_glwindow(&self, event_loop: &ActiveEventLoop) -> Rc<dyn GlWindow>

Source

fn rendering_context(&self) -> Rc<dyn RenderingContext>

This returns RenderingContext matching the viewport.

Source

fn window_rect(&self) -> DeviceIndependentIntRect

Provided Methods§

Source

fn update_user_interface_state( &self, _: &RunningAppState, _: &ServoShellWindow, ) -> bool

Inform the Window that the state of a WebView has changed and that it should do an incremental update of user interface state. Returns true if the user interface actually changed and a rebuild and repaint is needed, false otherwise.
