[PyOpenGL-Users] glNewList ArgumentError - wrong type

[Steven <ste...@gm...>]

Hi,

I'm using py27-opengl 3.0.1_0 and py27-opengl-accelerate 3.0.1_0 on MacOS 10.7.3 64 bit via macports.  I'm also using wxWidgets-devel 2.9.3_0+sdl if that's relevant.  
I've installed the wxgui component of gnuradio and am getting the following error when I try and use an openGL widget:

Traceback (most recent call last):
  File "/opt/local/lib/python2.7/site-packages/gnuradio/wxgui/plotter/plotter_base.py", line 187, in _on_paint
    for fcn in self._draw_fcns: fcn[1]()
  File "/opt/local/lib/python2.7/site-packages/gnuradio/wxgui/plotter/plotter_base.py", line 58, in draw
    GL.glNewList(self._grid_compiled_list_id, GL.GL_COMPILE)
ctypes.ArgumentError: argument 1: <type 'exceptions.TypeError'>: wrong type

The code is at http://pastebin.com/ezLmgYv2

Thanks,

Steven.

Please make sure GL.glGenLists is returning what you expect it to return
(namely an unsigned int). On some platforms I've seen PyOpenGL bindings not
returning the generated value but rather expecting to assign it to the
second parameter in a similar fashion than that of the C API.

Hope this helps!
Alejandro.-

Hi Alejandro,

		self._grid_compiled_list_id = GL.glGenLists(1)
		print self._grid_compiled_list_id
returns

'None'

So something seems amiss.

Steven.

Indeed.  glGenLists doesn't have any particular wrapper code.  It 
returns a simple uint given a count.  My guess would be either that your 
OS-X implementation doesn't support display lists in the mode you are 
using, or that you haven't yet got an OpenGL context (or something of 
that nature).

I've tested glGenLists with PyOpenGL head on Linux.  I don't have an 
OS-X machine on which to test, however.

Good luck,
Mike
