Snapshot

Required Methods

fn append_cairo(&self, bounds: &Rect) -> Context

Creates a new gsk::CairoNode and appends it to the current render node of @self, without changing the current node.

bounds

the bounds for the new node

Returns

a cairo::Context suitable for drawing the contents of the newly created render node

fn append_color(&self, color: &RGBA, bounds: &Rect)

Creates a new render node drawing the @color into the given @bounds and appends it to the current render node of @self.

You should try to avoid calling this function if @color is transparent.

color

the color to draw

bounds

the bounds for the new node

fn append_conic_gradient( &self, bounds: &Rect, center: &Point, rotation: f32, stops: &[ColorStop] )

Appends a conic gradient node with the given stops to @self.

bounds

the rectangle to render the gradient into

center

the center point of the conic gradient

rotation

the clockwise rotation in degrees of the starting angle. 0 means the starting angle is the top.

stops

the color stops defining the gradient

fn append_inset_shadow( &self, outline: &RoundedRect, color: &RGBA, dx: f32, dy: f32, spread: f32, blur_radius: f32 )

Appends an inset shadow into the box given by @outline.

outline

outline of the region surrounded by shadow

color

color of the shadow

dx

horizontal offset of shadow

dy

vertical offset of shadow

spread

how far the shadow spreads towards the inside

blur_radius

how much blur to apply to the shadow

fn append_layout(&self, layout: &Layout, color: &RGBA)

fn append_linear_gradient( &self, bounds: &Rect, start_point: &Point, end_point: &Point, stops: &[ColorStop] )

Appends a linear gradient node with the given stops to @self.

bounds

the rectangle to render the linear gradient into

start_point

the point at which the linear gradient will begin

end_point

the point at which the linear gradient will finish

stops

the color stops defining the gradient

fn append_node(&self, node: impl AsRef<RenderNode>)

Appends @node to the current render node of @self, without changing the current node.

If @self does not have a current node yet, @node will become the initial node.

node

a gsk::RenderNode
