All Implemented Interfaces:

DragGestureListener, DragSourceListener, Serializable, EventListener

public class IlvSDMDragSource
extends Object
implements DragGestureListener, DragSourceListener, Serializable

The class IlvSDMDragSource handles the "drag" part of drag-and-drop interactions between SDM engines. To enable drag-and-drop between two SDM engines, create an IlvSDMDragSource associated with one engine and an IlvSDMDropTarget associated with the other engine.
