29 29 * An abstract adapter class for receiving component events.
30 30 * The methods in this class are empty. This class exists as
31 31 * convenience for creating listener objects.
32 32 * <P>
33 33 * Extend this class to create a <code>ComponentEvent</code> listener
34 34 * and override the methods for the events of interest. (If you implement the
35 35 * <code>ComponentListener</code> interface, you have to define all of
36 36 * the methods in it. This abstract class defines null methods for them

37 37 * all, so you can only have to define methods for events you care about.)
38 38 * <P>
39 39 * Create a listener object using your class and then register it with a
40 40 * component using the component's <code>addComponentListener</code>
41 41 * method. When the component's size, location, or visibility
42 42 * changes, the relevant method in the listener object is invoked,
43 43 * and the <code>ComponentEvent</code> is passed to it.
