Class TreeSelectionEventManager

  extended by project35.desktopDeployment.TreeSelectionEventManager
All Implemented Interfaces:
java.util.EventListener, javax.swing.event.TreeSelectionListener

public class TreeSelectionEventManager
extends java.lang.Object
implements javax.swing.event.TreeSelectionListener

This class is used to govern tree selection events. The challenging part of Project35's use of a record tree is to prevent people from going to the next node if they have made an error in the previous one. You have to revert control back to the original node without triggering another event. Very annoying. this class was carefully constructed to prevent an endless chain of tree selection events from happening when this situation arises. NavigationTree delegates a lot of its management of selection events to this class.
