public interface ExtTreeWillExpandListener extends TreeWillExpandListener
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.
