Constructor Details

CompositeNode

public CompositeNode(MemorySegment address)

Create a CompositeNode instance for the provided memory address.

Parameters:

address - the memory address of the native object

CompositeNode

public CompositeNode(RenderNode child,
 RenderNode mask,
 PorterDuff op)

Creates a GskRenderNode that will composite the child onto the background with the given operator wherever the mask is set.

Note that various operations can modify the background outside of the child's bounds, so the mask may cause visual changes outside of the child.

Parameters:

child - The child to composite

mask - The mask where the compositing will apply

op - The compositing operator

Since:

4.22

Method Details

getType

public static @Nullable Type getType()

Get the GType of the CompositeNode class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected CompositeNode asParent()

Return this instance as if it were its parent type. Comparable to the Java super keyword, but ensures the parent typeclass is also used in native code.

Overrides:

asParent in class RenderNode

Returns:

the instance as if it were its parent type

getChild

public RenderNode getChild()

Gets the child node that is getting composited by the given node.

Returns:

the child GskRenderNode

Since:

4.22

getMask

public RenderNode getMask()

Gets the mask node that describes the region where the compositing applies.

Returns:

the mask GskRenderNode

Since:

4.22

getOperator

public PorterDuff getOperator()

Gets the compositing operator used by this node.

Returns:

The compositing operator

Since:

4.22
