# Interface DragSourceMotionListener

All Superinterfaces:
  `EventListener`

All Known Implementing Classes:
  `DragSourceAdapter, DragSourceContext`

public interface DragSourceMotionListener extends EventListener
A listener interface for receiving mouse motion events during a drag operation.

The class that is interested in processing mouse motion events during a drag operation either implements this interface or extends the abstract `DragSourceAdapter` class (overriding only the methods of interest).

Create a listener object using that class and then register it with a `DragSource`. Whenever the mouse moves during a drag operation initiated with this `DragSource`, that object's `dragMouseMoved` method is invoked, and the `DragSourceDragEvent` is passed to it.
