  32  * <P>
  33  * Extend this class to create a <code>ComponentEvent</code> listener
  34  * and override the methods for the events of interest. (If you implement the
  35  * <code>ComponentListener</code> interface, you have to define all of

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