### Class

# Gsk Renderer

since: 4.0

#### Description [src]

    abstract class Gsk.Renderer : GObject.Object
    {
      /* No available fields */
    }

`GskRenderer` is a class that renders a scene graph defined via a tree of `GskRenderNode` instances.

Typically you will use a `GskRenderer` instance to repeatedly call `gsk_renderer_render()` to update the contents of its associated `GdkSurface`.

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.
