Extend this class to create a ComponentEvent listener
and override the methods for the events of interest. (If you implement the
ComponentListener interface, you have to define all of
the methods in it. This abstract class defines null methods for them
all, so you can only have to define methods for events you care about.)
Create a listener object using your class and then register it with a
component using the component's addComponentListener
method. When the component's size, location, or visibility
changes, the relevant method in the listener object is invoked,
and the ComponentEvent is passed to it.
