## 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.

  Since:
    1.4
