Hi! How can I get continuous motion for the pointer, i.e. that it doesn't stop on the edge of the window (or root window). Is that possible, or do I have to deal with it myself, and warp the pointer to the other side of the window? I want to use pointer motion events to control a camera in my program.

How about reading the mouse cursor, then set it to the middle of the screen?

(Why aren't you using SDL? Xlib itself is going to become a legacy api in the next few years.)

don't warp the pointer. grabbing it will give you correct continuous motion

Mainly because I don't want to rely on SDL.
What makes you think Xlib is going to become a legacy api?

Unfortunatly it doesn't for me. I get positions from (0,0) - (width, height), if I restrict it to the window, if I don't restrict it, it will go the the edges of the root window, but stop there.

Care to elaborate?

I might do it as suggested by thec..
