package java.awt.event;
import java.util.EventListener;
The listener interface for receiving mouse motion events on a component.
(For clicks and other mouse events, use the MouseListener
.)
The class that is interested in processing a mouse motion event
either implements this interface (and all the methods it
contains) or extends the abstract MouseMotionAdapter
class
(overriding only the methods of interest).
The listener object created from that class is then registered with a
component using the component's addMouseMotionListener
method. A mouse motion event is generated when the mouse is moved
or dragged. (Many such events will be generated). When a mouse motion event
occurs, the relevant method in the listener object is invoked, and
the MouseEvent
is passed to it.
