public interface DragSourceListener
The 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.
| Method Summary | |
|---|---|
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. |

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.
