Class ParentTraversalEngine

java.lang.Object

com.sun.javafx.scene.traversal.TraversalEngine

com.sun.javafx.scene.traversal.ParentTraversalEngine

public final class ParentTraversalEngine
extends TraversalEngine

This traversal engine can be used to change algorithm for some specific parent/control that needs different traversal. This can be achieved by setting such engine using Parent.setImpl_traversalEngine(ParentTraversalEngine) and providing a special Algorithm implementation. Alternatively, the traversal engine can be w/o an algorithm and used just for listening to focus changes inside the specified parent.
