/**
* An abstract adapter class for receiving component events.
* The methods in this class are empty. This class exists as
* convenience for creating listener objects.
* <P>
* Extend this class to create a <code>ComponentEvent</code> listener
* and override the methods for the events of interest. (If you implement the
* <code>ComponentListener</code> 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.)
* <P>
* Create a listener object using your class and then register it with a
* component using the component's <code>addComponentListener</code>
* method. When the component's size, location, or visibility
* changes, the relevant method in the listener object is invoked,
* and the <code>ComponentEvent</code> is passed to it.
