Method Detail

commitDrag

public void commitDrag()
The SelectionTool supports keyboard accessible drags. In such scenarios it is up to the SelectionTool to interpret commit and abort keystrokes. Since the DragTracker cannot do this, this method is used to indicate that the User has committed the drag using the keyboard. Abort is not handled specially, and the DragTracker should peform the usual cleanup in its Tool.deactivate() method.
