|
|
* #GskRenderer is a class that renders a scene graph defined via a
|
|
|
|
* tree of #GskRenderNode instances.
|
|
|
|
*
|
|
|
|
* Typically you will use a #GskRenderer instance with a #GdkDrawingContext
|
|
|
|
* associated to a #GdkWindow, and call gsk_renderer_render() with the
|
|
|
|
* drawing context and the scene to be rendered.
|
|
|
|
*
|
|
|
|
* It is necessary to realize a #GskRenderer instance using gsk_renderer_realize()
|
|
|
|
* before calling gsk_renderer_render(), in order to create the appropriate
|
|
|
|
* windowing system resources needed to render the scene.
