[PyOpenGL-Users] Changes in glutCreateMenu from v 2.0.1 to 3.0.0 ?

[Neal H. <nh...@do...>]

Hi,

I tried to find the answer myself -- I really did -- but now I seem
to be at a dead end.  

This worked in 2.0.1.09.dfsg.1-0.3 on ubuntu feisty:

    def handleSelect( self, index ):
        """Handle menu item selection by calling the handler specified
        in the menu description."""
        try:
            name, fn = self.dispatchTable[index]
        except:
            return
        if callable(fn):
            fn()

    def create_menu( self, items ):
        """Create the open GL menu based on the menu descriptor in 'items'."""
        id = glutCreateMenu( self.handleSelect )
        ...

but not in 3.0.0 on ubutnu gutsy.  On that
last line ("id = glutCreateMenu...") I get:

Traceback (most recent call last):
  File "./viewframe", line 21, in <module>
    app = FrameViewer( fd=framedata )
  File "../OpenGL/GLFramework.py", line 90, in __init__
    self.init_GL()
  File "../OpenGL/GLFramework.py", line 358, in init_GL
    m = GLMenu( menu )
  File "../OpenGL/GLFramework.py", line 853, in __init__
    self.create_menu( items )
  File "../OpenGL/GLFramework.py", line 868, in create_menu
    id = glutCreateMenu( self.handleSelect )
  File "/usr/lib/python2.5/site-packages/OpenGL/GLUT/special.py", line 165, in glutCreateMenu
    result = simple.glutCreateMenu( cCallback )
ctypes.ArgumentError: argument 1: <type 'exceptions.TypeError'>: expected CFunctionType instance instead of CFunctionType

-----------------------------------

Some of the other problems I had when searching for solution:

 1. In the documentation, 

     http://pyopengl.sourceforge.net/documentation/manual/glutCreateMenu.3GLUT.xml

     clicking on the Python Sample Code link at the bottom results in 
     a server timeout (cvs.sourceforge...)

 2. Ubuntu feisty had the Demo/suit/GLUT.py file, but there was nothing
     obvious from looking at that (of course, it was on a system whose
     version worked).

 3. Ubuntu gutsy doesan't have that file, nor could I find it in any of the
     places I looked.

Thanks
