  32  * <P>
  33  * Mouse motion events occur when a mouse is moved or dragged.
  34  * (Many such events will be generated in a normal program.
  35  * To track clicks and other mouse events, use the MouseAdapter.)
  36  * <P>
  37  * Extend this class to create a <code>MouseEvent</code> listener
  38  * and override the methods for the events of interest. (If you implement the
  39  * <code>MouseMotionListener</code> interface, you have to define all of
  40  * the methods in it. This abstract class defines null methods for them
  41  * all, so you can only have to define methods for events you care about.)
  42  * <P>
  43  * Create a listener object using the extended class and then register it with
  44  * a component using the component's <code>addMouseMotionListener</code>
  45  * method. When the mouse is moved or dragged, the relevant method in the
  46  * listener object is invoked and the <code>MouseEvent</code> is passed to it.
