  29   29   * An abstract adapter class for receiving mouse 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   * Mouse events let you track when a mouse is pressed, released, clicked,
  34   34   * moved, dragged, when it enters a component, when it exits and
  35   35   * when a mouse wheel is moved.
  36   36   * <P>
  37   37   * Extend this class to create a {@code MouseEvent}
  38   38   * (including drag and motion events) or/and {@code MouseWheelEvent}
  39   39   * listener and override the methods for the events of interest. (If you implement the
  40   40   * {@code MouseListener},
  41   41   * {@code MouseMotionListener}
  42   42   * interface, you have to define all of
  43   43   * the methods in it. This abstract class defines null methods for them
  44   44   * all, so you can only have to define methods for events you care about.)
  45   45   * <P>
  46   46   * Create a listener object using the extended class and then register it with
  47   47   * a component using the component's {@code addMouseListener}
  48   48   * {@code addMouseMotionListener}, {@code addMouseWheelListener}
  49   49   * methods.
  50   50   * The relevant method in the listener object is invoked  and the {@code MouseEvent}
  51   51   * or {@code MouseWheelEvent}  is passed to it in following cases:
  52   52   * <ul>
  53   53   * <li>when a mouse button is pressed, released, or clicked (pressed and  released)
  54   54   * <li>when the mouse cursor enters or exits the component
  55   55   * <li>when the mouse wheel rotated, or mouse moved or dragged

  56   56   * </ul>
