[ CCode ( type_id = "gsk_renderer_get_type ()" ) ]
public abstract class Renderer : Object

`GskRenderer` is a class that renders a scene graph defined via a tree of [class@Gsk.

RenderNode] instances.

Typically you will use a `GskRenderer` instance to repeatedly call [method@Gsk.Renderer.render] to update the contents of its associated [ class@Gdk.Surface].

It is necessary to realize a `GskRenderer` instance using [method@Gsk.Renderer.realize] before calling [method@Gsk.Renderer.render], in order to create the appropriate windowing system resources needed to render the scene.

All known sub-classes:

VulkanRenderer

Namespace: Gsk

Package: gtk4

Content:

Properties:

public bool realized { get; }
Whether the renderer has been associated with a surface or draw context.
public Surface surface { get; }
The surface associated with renderer.

Static methods:

public static Renderer? for_surface (Surface surface)
Creates an appropriate `GskRenderer` instance for the given surface.

Creation methods:

protected Renderer ()

Methods:

public unowned Surface? get_surface ()
Retrieves the `GdkSurface` set using gsk_enderer_realize.
public bool is_realized ()
Checks whether the this is realized or not.
public bool realize (Surface? surface) throws Error
Creates the resources needed by the this to render the scene graph.
public bool realize_for_display (Display display) throws Error
Creates the resources needed by the this to render the scene graph.
public void render (RenderNode root, Region? region)
Renders the scene graph, described by a tree of `GskRenderNode` instances to the renderer's surface, ensuring that the given region gets redrawn.
public Texture render_texture (RenderNode root, Rect? viewport)
Renders the scene graph, described by a tree of `GskRenderNode` instances, to a `GdkTexture`.
public void unrealize ()
Releases all the resources created by realize.
