Interface ExtTreeWillExpandListener

All Superinterfaces:

EventListener, TreeWillExpandListener

public interface ExtTreeWillExpandListener
extends TreeWillExpandListener

A trivial extension to TreeWillExpandListener, to allow listeners to be notified if another TreeWillExpandListener vetos a pending expansion. If a TreeExpansionListener added to an instance of TreePathSupport implements this interface, it will be notified by the TreePathSupport if some other listener vetos expanding a node.

This interface is primarily used to avoid memory leaks if a TreeWillExpandListener constructs some data structure (like a TableModelEvent that is a translation of a TreeExpansionEvent) for use when the expansion actually occurs, to notify it that the pending TableModelEvent will never be fired. It is not of much interest to the rest of the world.
