java.lang.Object

org.eclipse.gef4.mvc.behaviors.AbstractBehavior<javafx.scene.Node>

org.eclipse.gef4.mvc.fx.behaviors.FXViewportBehavior

All Implemented Interfaces:

java.beans.PropertyChangeListener, java.util.EventListener, IActivatable, IAdaptable.Bound<IVisualPart<javafx.scene.Node,? extends javafx.scene.Node>>, IPropertyChangeNotifier, IBehavior<javafx.scene.Node>

public class FXViewportBehavior
extends AbstractBehavior<javafx.scene.Node>
implements java.beans.PropertyChangeListener

The FXViewportBehavior can be registered on an FXRootPart in order to keep the ViewportModel in sync with the ScrollPaneEx of the FXViewer and vice versa.
