}

The host of a visual tree: connects the tree to its renderer, layout root and input root.

Required Methods

fn root_visual(&self) -> Option<Ref<Visual>>

The root visual of the tree.

fn render_scaling(&self) -> f64

The scaling factor to use in rendering.

fn renderer(&self) -> Rc<dyn IRenderer>

The renderer of the tree.

fn layout_root(&self) -> Rc<dyn ILayoutRoot>

The layout root of the tree.

fn client_size(&self) -> Size

The size of the client area, in device-independent pixels.

fn hit_tester(&self) -> Rc<dyn IHitTester>

The hit tester of the tree.

fn input_root(&self) -> Rc<dyn IInputRoot>

The input root of the tree.

Provided Methods

fn platform_settings(&self) -> Option<Rc<dyn IPlatformSettings>>

The platform settings of the host, if it has any.

fn point_to_screen(&self, _point: Point) -> Option<PixelPoint>

Converts a point from client to screen coordinates, if the host is on a screen.

fn point_to_client(&self, _point: PixelPoint) -> Option<Point>

Converts a point from screen to client coordinates, if the host is on a screen.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
