- Direct Known Subclasses:
- BasicComboPopup.InvocationMouseMotionHandler, BasicComboPopup.ListMouseMotionHandler
public abstract class MouseMotionAdapter - extends Object
- implements MouseMotionListener
An abstract adapter class for receiving mouse motion events.
The methods in this class are empty. This class exists as
convenience for creating listener objects.
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.

MouseMotionAdapter
public MouseMotionAdapter()
mouseDragged
public void mouseDragged(MouseEvent e)
- Invoked when a mouse button is pressed on a component and then
dragged. Mouse drag events will continue to be delivered to
the component where the first originated until the mouse button is
released (regardless of whether the mouse position is within the
bounds of the component).
- Specified by:
mouseDragged in interface MouseMotionListener
mouseMoved
public void mouseMoved(MouseEvent e)
- Invoked when the mouse button has been moved on a component
(with no buttons no down).
- Specified by:
mouseMoved in interface MouseMotionListener
