A component that can be used by widgets to draw themselves on a screen.

Required Methods

fn start_layer(&mut self, bounds: Rectangle)

Starts recording a new layer.

fn end_layer(&mut self)

Ends recording a new layer.

The new layer will clip its contents to the provided bounds.

fn start_transformation(&mut self, transformation: Transformation)

Starts recording with a new Transformation.

fn end_transformation(&mut self)

Ends recording a new layer.

The new layer will clip its contents to the provided bounds.

fn fill_quad(&mut self, quad: Quad, background: impl Into<Background>)

Fills a Quad with the provided Background.

fn clear(&mut self)

Clears all of the recorded primitives in the Renderer.

Provided Methods

fn with_layer(&mut self, bounds: Rectangle, f: impl FnOnce(&mut Self))

Draws the primitives recorded in the given closure in a new layer.

The layer will clip its contents to the provided bounds.

fn with_transformation( &mut self, transformation: Transformation, f: impl FnOnce(&mut Self) )

Applies a Transformation to the primitives recorded in the given closure.

fn with_translation(&mut self, translation: Vector, f: impl FnOnce(&mut Self))

Applies a translation to the primitives recorded in the given closure.
