0N/A/**
0N/A * An abstract adapter class for receiving mouse motion events.
0N/A * The methods in this class are empty. This class exists as
0N/A * convenience for creating listener objects.
0N/A * <P>
0N/A * Mouse motion events occur when a mouse is moved or dragged.
0N/A * (Many such events will be generated in a normal program.
0N/A * To track clicks and other mouse events, use the MouseAdapter.)
0N/A * <P>
0N/A * Extend this class to create a <code>MouseEvent</code> listener
0N/A * and override the methods for the events of interest. (If you implement the
0N/A * <code>MouseMotionListener</code> interface, you have to define all of
0N/A * the methods in it. This abstract class defines null methods for them
0N/A * all, so you can only have to define methods for events you care about.)
0N/A * <P>
0N/A * Create a listener object using the extended class and then register it with
0N/A * a component using the component's <code>addMouseMotionListener</code>
0N/A * method. When the mouse is moved or dragged, the relevant method in the
0N/A * listener object is invoked and the <code>MouseEvent</code> is passed to it.
