public class IlvSDMDragSource extends Object implements DragGestureListener, DragSourceListener, Serializable
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.Constructor and Description |
---|
IlvSDMDragSource(IlvSDMEngine engine,
