/**
* An abstract adapter class for receiving mouse events.
* The methods in this class are empty. This class exists as
* convenience for creating listener objects.
* <P>
* Mouse events let you track when a mouse is pressed, released, clicked,
* when it enters a component, and when it exits.
* (To track mouse moves and mouse drags, use the MouseMotionAdapter.)
* <P>
* Extend this class to create a <code>MouseEvent</code> listener
* and override the methods for the events of interest. (If you implement the
* <code>MouseListener</code> interface, you have to define all of
* the methods in it. This abstract class defines null methods for them
* all, so you can only have to define methods for events you care about.)
* <P>
* Create a listener object using the extended class and then register it with
* a component using the component's <code>addMouseListener</code>
* method. When a mouse button is pressed, released, or clicked (pressed and
* released), or when the mouse cursor enters or exits the component,
* the relevant method in the listener object is invoked
* and the <code>MouseEvent</code> is passed to it.
