y.view.hierarchy
Class GroupNodeRealizer.StateChangeListener

java.lang.Object
  y.view.hierarchy.GroupNodeRealizer.StateChangeListener

All Implemented Interfaces:

EventListener, HierarchyListener

Enclosing class:

GroupNodeRealizer

public static class GroupNodeRealizer.StateChangeListener
extends Object
implements HierarchyListener

This static inner class can be used to automatically adjust the groupClosed property of GroupFeature instances. Add this HierarchyListener implementation to the respective HierarchyManager instances and changes of the group nodes' states will be automatically reflected by the groupClosed property. This implementation works together with all GroupFeature implementations (e.g. GroupNodeRealizer and GenericGroupNodeRealizer) implementations as well as proxy node realizer instances that contain an open (index 0) and a closed (index 1) variant at the same time.
