User-Interface

[Johannes]

How can I end a callback-function?

def mymousemove(horz, vert):
print 'My mouse moved to: ', horz, vert

viz.callback(viz.MOUSEMOVE_EVENT, mymousemove)

Not important, just to tell you why I need this:
The new idea to add User interaction is to put some sliders in the scene e.g. on the table.
I was thinking about something like this: as soon as the user clicks on his/her mouse (with a tracker-light taped to it) in a certain area of the scene, a UserInterfaceFunction to change a certain slider is called (identification by position).
When he drags the mouse now to a certain position and releases the mouse it changes something in the room, e.g. the light...

When he releases the mouse button the callback-function for mousemoved should exit (performance...), how do I do that?
