Detailed Description

Receives change event callbacks that are sent out by a ChangeBroadcaster.

A ChangeBroadcaster keeps a set of listeners to which it broadcasts a message when the ChangeBroadcaster::sendChangeMessage() method is called. 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.
