  +--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 GroupNodeRealizer 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 both GroupNodeRealizer implementations and CompositeNodeRealizer instances that contain an open (index 0) and a closed (index 1) variant at the same time.
