Writing a Mouse Motion Listener

Mouse motion events tell you when the user moves the onscreen cursor using the mouse or a similar input device. For information on tracking other mouse event types such as clicks, see Writing a Mouse Listener.

Mouse Motion Event Methods

The MouseMotionListener interface and its corresponding adapter class, MouseMotionAdapter, contain two methods:

void mouseDragged(MouseEvent)

Notifies the listener ...

void mouseMoved(MouseEvent)

Notifies the listener ...

The MouseEvent Class

Each mouse motion event method has a single parameter -- and it's not called MouseMotionEvent! Instead, mouse motion event methods use MouseEvent objects. See Writing a Mouse Listener for information about the MouseEvent class.
