Class DragSourceDropEvent

java.awt.dnd.DragSourceDropEvent

All Implemented Interfaces:: Serializable

public class DragSourceDropEvent extends DragSourceEvent

The DragSourceDropEvent is delivered from the DragSourceContextPeer, via the DragSourceContext, to the dragDropEnd method of DragSourceListeners registered with that DragSourceContext and with its associated DragSource. It contains sufficient information for the originator of the operation to provide appropriate feedback to the end user when the operation completes.
