[PyOpenGL-Users] Multiple togl widgets bug?

[Jozef V. <ve...@gj...>]

Good day,

I started playing with OpenGL in python and just can't 
figure out - why this works:

   from Tkinter import Frame
   f = Frame(width = 200, height = 200)
   f.pack()
   f.mainloop()
   f = Frame(width = 200, height = 200)
   f.pack()
   f.mainloop()

shows second window after closing first one

- this does not:

   from OpenGL.Tk import Opengl
   o = Opengl(width = 200, height = 200)
   o.redraw = lambda x: None
   o.pack()
   o.mainloop()
   o = Opengl(width = 200, height = 200)
   o.redraw = lambda x: None
   o.pack()
   o.mainloop()

shows first window, and crashes after it is closed

Traceback (most recent call last):
   File "./test.py", line 11, in ?
     o = Opengl(width = 200, height = 200)
   File "/usr/lib/python2.4/site-packages/OpenGL/Tk/__init__.py", line 233, in __init__
     apply(RawOpengl.__init__, (self, master, cnf), kw)
   File "/usr/lib/python2.4/site-packages/OpenGL/Tk/__init__.py", line 188, in __init__
     Widget.__init__(self, master, 'togl', cnf, kw)
   File "/usr/lib/python2.4/lib-tk/Tkinter.py", line 1862, in __init__
     self.tk.call(
_tkinter.TclError: invalid command name "togl"

Those are results form TOgl-1.5,
1.6 crashed after import,
1.7 did not work either (I tried, but I don't remeber symptoms)

Thanks for any hints

Good bye
