public abstract class RenderNode

`GskRenderNode` is the basic block in a scene graph to be rendered using [class@Gsk.

Renderer].

Each node has a parent, except the top-level node; each node may have children nodes.

Each node has an associated drawing surface, which has the size of the rectangle set when creating it.

Render nodes are meant to be transient; once they have been associated to a [class@Gsk.Renderer] it's safe to release any reference you have on them. All [class@Gsk.RenderNode]s are immutable, you can only specify their properties during construction.

All known sub-classes:

Static methods:

public static RenderNode? deserialize (Bytes bytes, ParseErrorFunc? error_func)
Loads data previously created via [method@Gsk.

Creation methods:

protected RenderNode ()

Methods:

public unowned RenderNode @ref ()
Acquires a reference on the given `GskRenderNode`.
public void draw (Context cr)
Draw the contents of this to the given cairo context.
public Rect get_bounds ()
Retrieves the boundaries of the this.
public RenderNodeType get_node_type ()
Returns the type of the this.
public Bytes serialize ()
Serializes the this for later deserialization via deserialize.
public void unref ()
