Class SynchronizeChildrenOnZoomBehavior

java.lang.Object

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

org.eclipse.gef4.zest.fx.behaviors.SynchronizeChildrenOnZoomBehavior

All Implemented Interfaces:

IActivatable, IAdaptable.Bound<IVisualPart<javafx.scene.Node,? extends javafx.scene.Node>>, IPropertyChangeNotifier, IBehavior<javafx.scene.Node>

public class SynchronizeChildrenOnZoomBehavior
extends AbstractBehavior<javafx.scene.Node>

The SynchronizeChildrenOnZoomBehavior starts a content synchronization for the NodeContentPart on which it is installed when the zoom level is changed. This enables the NodeContentPart to report a nested Graph as a child depending on the zoom level (see NodeContentPart.getContentChildren()).
