If there's ever a way to integrate VPython inside of wxWidgets (I don'tthink there is right now), then I dare say PyGeo would benefit by moving to wxWidgets. Arthur's Tk menus and controls could be re-rendered in a more capable framework. Plus he'd get the benefit of a more consistent look on the different platforms (this would be especially noticeable on Mac OSX).

Remember that the gui intensive Leo found no reason to go beyond TK. TK's capabilities and Arthur's capabilities with TK being different issues ;) Current VPython uses GTK1 on Linux (where an addtional component for creating a GTK OpenGL canvas is necessary) and a native OpenGL canvas for Windows. VPython is working toward some integration with PyOpenGL. Which will be very cool. I am hoping this will also mean that it will eventually render onto any OpenGL capable widget - which would include wxPython and PyGame, among others. Last I looked, the _tkinter OpenGL widget, which has always been a bit of a pain, was out of commission. At the point that VPython offers more flexibility, I will need to reassess my options. And look forward to it. All evidence still pointing to the fact that I have gotten on the right horses, for the kinds the things I have been exploring, and hoping to encourage others to explore. Art
