Constructor Details

SubsurfaceNode

public SubsurfaceNode(MemorySegment address)

Create a SubsurfaceNode proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

SubsurfaceNode

public SubsurfaceNode(RenderNode child,
 @Nullable
 @Nullable MemorySegment subsurface)

Creates a GskRenderNode that will possibly divert the child node to a subsurface.

Note: Since subsurfaces are currently private, these nodes cannot currently be created outside of GTK. See GtkGraphicsOffload.

Parameters:

child - The child to divert to a subsurface

subsurface - the subsurface to use

Method Details

getType

public static Type getType()

Get the GType of the SubsurfaceNode class

Returns:

the GType

asParent

protected SubsurfaceNode asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class RenderNode

getSubsurface

public static MemorySegment getSubsurface(DebugNode node)

Gets the subsurface that was set on this node

Parameters:

node - a debug GskRenderNode

Returns:

the subsurface

getChild

public RenderNode getChild()

Gets the child node that is getting drawn by the given this SubsurfaceNode.

Returns:

the child GskRenderNode
