about pyopengl

[shanjunxu]

I am a chinese boy,my english is not good,so i don not know how to
tell you about my question,i hope you can understand what i say.
I like python, and now i using pyopengl to draw three-dimensional.
but how can i use mouse to control objects?such as selecting object.I
know a function( glSelectBuffer() ) can be used,In C language the
format is glSelectBuffer(size, buffer), but in python the format is
glSelectBuffer(size), how can i get the "buffer" pointer?
The following is one section function of my codes:
def ProcessSelection(x,y):
viewport=range(4)
glSelectBuffer(64)
viewport=glGetIntegerv(GL_VIEWPORT)
glMatrixMode(GL_PROJECTION)
glPushMatrix()
glRenderMode(GL_SELECT)
glLoadIdentity()
gluPickMatrix(x, viewport[3]-y, 2, 2, viewport)
gluPerspective(45.0, aspect, 0.1, 200.0)

DrawButton()
hits=glRenderMode(GL_RENDER)

glMatrixMode(GL_PROJECTION)
glPopMatrix()
glMatrixMode(GL_MODELVIEW)

If you know how to do ,can you mail to me?thank you!
