public interface DragSourceListener extends EventListener
DragSourceListener defines the
 event interface for originators of
 Drag and Drop operations to track the state of the user's gesture, and to
 provide appropriate "drag over"
 feedback to the user throughout the
 Drag and Drop operation.
 
 The drop site is associated with the previous dragEnter()
 invocation if the latest invocation of dragEnter() on this
 listener:
 
dragExit() invocation on this listener.
 | Modifier and Type | Method and Description | 
|---|---|
| void | dragDropEnd(DragSourceDropEvent dsde)This method is invoked to signify that the Drag and Drop
 operation is complete. | 
| void | dragEnter(DragSourceDragEvent dsde)Called as the cursor's hotspot enters a platform-dependent drop site. | 
| void | dragExit(DragSourceEvent dse)Called as the cursor's hotspot exits a platform-dependent drop site. | 
| void | dragOver(DragSourceDragEvent dsde)Called as the cursor's hotspot moves over a platform-dependent drop site. | 
| void | dropActionChanged(DragSourceDragEvent dsde)Called when the user has modified the drop gesture. |

DragSourceDropEvent can be used to
 determine the termination state. The getDropAction() method
 returns the operation that the drop site selected
 to apply to the Drop operation. Once this method is complete, the
 current DragSourceContext and
 associated resources become invalid.dsde - the DragSourceDropEvent Submit a bug or feature
