public class VetoableTreeStructureChangeEvent

extends java.util.EventObject

The event object for a tree structure change. Listeners to this event type have the power to veto the change, in which case it will not happen.

In an unfortunate turn of events (some would call it a design glitch, others will fess up and call it laziness), this event class is used for two distinct types of tree structure changes. For each of these two, some of our properties will make sense and others should be ignored. This is how it works;

1. When a node is renamed, an event is filled in with its oldName, newName, source and node properties set. All others should be ignored as they will generally by null or zero or somesuch.
2. When a node is moved, an event is filled in with its oldParent, oldIndex, newParent, newIndex, source and node properties set. All others should be ignored as they will generally by null or zero or somesuch.
