Not really sure what you're trying to do, whether you mean "moving the 
mouse cursor to the center of the window", which is often called 
"warping" the pointer, or whether you mean you want access to the mouse 
position in your window.  Both are functions of the GUI library you use 
(i.e. PyGame, GLUT, Tkinter, FxPy or wxPython).

There is a wxGLCanvas class which provides a fairly generic OpenGL 
canvas.  You can see such a canvas in the wxPython demo, as well as in 
OpenGLContext's wxcontext.py module.

You'll have to wait for the next release or use the CVS repository and 
rebuild the wrappers with swig 1.3.13.  I'll be trying to get enough 
time to do a release this upcoming weekend.

BTW, you might want to check out some of the other simple Python 3D 
scenegraph engines, such as Zoe or SPyRE, you can find links to them here:
    http://www.vrplumber.com/py3d.py?category=retained
and consider using them as a starting point (keeping in mind that those 
two are LGPL-licensed).

Have fun,
Mike
