GLUT on windows usually does not catch mousewheel events for me. (Although it seems to me that is has worked sporadically over past years and versions.) GLUT on Linux does catch wheel events nicely -- but read on anyway... Freeglut (which is open source) is an (almost) direct binary replacement for GLUT, and it *does* catch mousewheel events. (On both Windows and Linux.) Is there a reason this answer is not satisfactory? If you're not *forced* to use GLUT, use FREEGLUT and your problem is solved with no additional work. If you *are* forced to use GLUT, rebel. GLUT has not been maintained for more than 10 years, is showing its age, and is licensed in such a way that you can't modify it. Use FREEGLUT instead: see http://freeglut.sourceforge.net/

If you did, for whatever reason I didn't see it; I just rechecked my inbox to be sure. Thanks for doing so again! I assume, given the list we're on, that Freeglut can be used with Python. I'll look into it. Thanks for the pointer! -- Craig Berry - http://www.cine.net/~cberry/ "Lots of things in the universe dont solve any problems, and nevertheless exist." -- Sean Carroll

PyOpenGL has bindings for all the procedures in GLUT/FREEGLUT. Just tell PyOpenGL to use the freeglut library instead, or even just copy freeglut (.dll or .so or whatever) over your existing glut library (glut32.dll or whatever). It really can serve as a binary drop in replacement. Gary Herron
From: Craig Berry on 10 Feb 2010 12:38 I'm happy to report that FreeGLUT solved my problem. I obtained the Windows prepackaged binary distribution, pulled out freeglut.dll, renamed it to glut32.dll, and replaced the existing glut32.dll in the PyOpenGL installation directory tree with the new version. Mousewheel events are now reported, and everything else seems to be working as expected.
