  29   29   * An abstract adapter class for receiving keyboard focus 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>FocusEvent</code> listener
  34   34   * and override the methods for the events of interest. (If you implement the
  35   35   * <code>FocusListener</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 the extended class and then register it with
  40   40   * a component using the component's <code>addFocusListener</code>
  41   41   * method. When the component gains or loses the keyboard focus,
  42   42   * the relevant method in the listener object is invoked,
  43   43   * and the <code>FocusEvent</code> is passed to it.
