Thanks!

So, if I understand the thread correctly, I can register this callback:

  extern "C" static void callback_fun(int button, int state, int x, int y);

from my C++ class:

  glutMouseFunc (callback_fun);

...and have callback_fun() call my class?

I tried something similar, but didn't have the {extern "C"} prefix.


It is interesting that the program runs most of the time, anyway.
Even with a {static} C++ member function.  Most of the callbacks work,
and even the mouse-button callback works as long as I don't spin the
scroll wheel.


Thanks again.
