Implementations

impl FramebufferToplevelImpl

pub fn new( output_backend: Arc<dyn IOutputBackend>, input_backend: Rc<dyn IInputBackend>, queue: Option<Rc<dyn IRawEventGrouperDispatchQueue>>, compositor: Option<Rc<Compositor>>, ) -> Rc<Self>

Creates the top-level over an output and starts the input backend. queue is the raw event queue of the platform and compositor its compositor (statics of the platform in the reference).

pub fn mouse_device(&self) -> Rc<dyn IMouseDevice>

pub fn frame_size(&self) -> Option<Size>

Converts a point from screen to client coordinates.

fn point_to_screen(&self, point: Point) -> PixelPoint

Converts a point from client to screen coordinates.

fn set_cursor(&self, _cursor: Option<Rc<dyn ICursorImpl>>)
