How to make 3d Widget real mouse follow virtual mouse?

Hey, thanks for your dedication to my problem, however, I want my real mouse to be teleported to exact location of my fake mouse which is driven by mouse delta. I am not sure I understand how to get the exact location of the virtual mouse? So I just want the debug sphere (real mouse) to follow virtual mouse exactly. Or even better, jus restrict the real mouse to the 3d widget bounds. Is that possible?
