dragFinished
public void dragFinished(DragSourceEvent event)
This implementation ofdragFinished
disposes the image that was created inTableDragSourceEffect.dragStart
. Subclasses that override this method should callsuper.dragFinished(event)
to dispose the image in the default implementation.- Specified by:
dragFinished
in interfaceDragSourceListener
- Overrides:
dragFinished
in classDragSourceAdapter
- Parameters:
event
- the information associated with the drag finished event- See Also:
DragSourceEvent

will create a default image that will be used during the drag. The image should be disposed when the drag is completed in theTableDragSourceEffect.dragFinished
method. Subclasses that override this method should callsuper.dragStart(event)
to use the image from the default implementation.- Specified by:
dragStart
in interfaceDragSourceListener
- Overrides:
dragStart
in classDragSourceAdapter
- Parameters:
