## java.awt.event
Class MouseMotionAdapter

    java.lang.Object
      java.awt.event.MouseMotionAdapter

All Implemented Interfaces:
  MouseMotionListener, EventListener

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.

  1.1

Constructor Detail

### MouseMotionAdapter

    public MouseMotionAdapter()

Method Detail

### 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`
