public abstract class MouseMotionAdapter extends Object implements MouseMotionListener
Mouse motion events occur when a mouse is moved or dragged. (Many such events will be generated in a normal program. To track clicks and other mouse events, use the MouseAdapter.)
Extend this class to create a MouseEvent
listener and override the methods for the events of interest. (If you implement the MouseMotionListener
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.)
Create a listener object using the extended class and then register it with a component using the component's addMouseMotionListener
method. When the mouse is moved or dragged, the relevant method in the listener object is invoked and the MouseEvent
is passed to it.
