#[repr(transparent)]pub struct Renderer { /* private fields */ }Expand description
Renderer is a class that renders a scene graph defined via a
tree of RenderNode instances.
Typically you will use a Renderer instance to repeatedly call
GskRendererExt::render() to update the contents of its associated
gdk::Surface.
It is necessary to realize a Renderer instance using
GskRendererExt::realize() before calling GskRendererExt::render(),
in order to create the appropriate windowing system resources needed
to render the scene.
This is an Abstract Base Class, you cannot instantiate it.

impl Renderer
pub const NONE: Option<&'static Renderer> = None
sourcepub fn for_surface(surface: &Surface) -> Option<Renderer>
pub fn for_surface(surface: &Surface) -> Option<Renderer>
Creates an appropriate Renderer instance for the given @surface.
If the GSK_RENDERER environment variable is set, GSK will
try that renderer first, before trying the backend-specific
default. The ultimate fallback is the cairo renderer.
The renderer will be realized before it is returned.
