draggerContext draw marque?

Hey guys, I have a simple draggerContext tool that prints the left top corner and bottom right corner of the dragging event. The problem is that the tool doesnt have any visual draw like the marque tool for instance. Is it possible to do that? I just need to see the rectangle draw while dragging.
