Mouse event: how to detect no mouse move event, how to set mouse position?

[Zhi]

Hi,

I am writing a program, which detects the mouse movement event and does certain stuff. However, when the mouse stops moving, I need to reset a variable. Is there an event that I can use to do this?

If there is no way to detect the non-movement event, a way around is to check the mouse position change periodically. However, when the mouse moves to the edge of the window or screen, its position value will be fixed. Is there any way to reset the mouse position? I see the viz.mouse.getposition(). Is there something like viz.mouse.setposition() that I can use?

Thanks,
Zhi
