Constraining mouse cursor globally in xorg
Hi, Not sure if this is the right place for this question, but here goes.. I need to constrain the mouse cursor in xorg, to prevent it reaching an area of screen that is not visible to the user (don't ask). I've noticed that there is support for this within the x server using the ConstrainCursor function. What this function provides is exactly what I need. What's not clear to me is how I can access this function from the application level. (or is it internal only?). None of the pScreen member functions appear to be exposed in the libraries I've searched. Do I need to write a simple xorg module to do this? Any suggestions on how to proceed? Thanks, Alex. ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg

How about: http://tronche.com/gui/x/xlib/input/XGrabPointer.html http://tronche.com/gui/x/xlib/input/XWarpPointer.html To make it global could be done in the window manager maybe. ___ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg

Grabbing the pointer would stop event delivery to other clients though and would only work provided it's a single client that the pointer needs to be constrained within.
