Detailed Description

Receives callbacks about changes to some kind of object.

Many objects use a ChangeListenerList to keep a set of listeners which they will inform when something changes. A subclass of ChangeListener is used to receive these callbacks.

Note that the major difference between an ActionListener and a ChangeListener is that for a ChangeListener, multiple changes will be coalesced into fewer callbacks, but ActionListeners perform one callback for every event posted.
