Examples of org.eclipse.swt.dnd.DropTarget.addDropListener()

org.eclipse.swt.dnd.DropTarget.addDropListener()
Adds the listener to the collection of listeners who will be notified when a drag and drop operation is in progress, by sending it one of the messages defined in the DropTargetListener interface.
- dragEnter is called when the cursor has entered the drop target boundaries
- dragLeave is called when the cursor has left the drop target boundaries and just before the drop occurs or is cancelled.
- dragOperationChanged is called when the operation being performed has changed (usually due to the user changing the selected modifier key(s) while dragging)
- dragOver is called when the cursor is moving over the drop target
- dropAccept is called just before the drop is performed. The drop target is given the chance to change the nature of the drop or veto the drop by setting the event.detail field
- drop is called when the data is being dropped
@param listener the listener which should be notified @exception IllegalArgumentException
- ERROR_NULL_ARGUMENT - if the listener is null
@exception SWTException
- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
