Summary: WGL ChoosePixelFormat calling error
Initial Comment:
System: Win98, Python 2.2.2
PYOPENGL-2.0.0.44.WIN32-PY2.2.EXE
Win32 extensions v.148
Trying to run the openGLDemo .py included with Pythonwin, I
cannot execute
pfd = createPIXELFORMATDESCRIPTOR()
because I don't seem to have that function.
I replaced the call with
pfd = PIXELFORMATDESCRIPTOR()
<snip value assignments>
ppfd = PIXELFORMATDESCRIPTORPtr(pfd)
the call that causes problems is
pixelformat = ChoosePixelFormat(dc, ppfd)
with the following trace
File "C:\Python22\Lib\site-
packages\Pythonwin\pywin\Demos\openGLDemo.py", line 121,
in _SetupPixelFormat
pixelformat = ChoosePixelFormat(dc, ppfd)
TypeError: Type error. Expected
_p_q_const__PIXELFORMATDESCRIPTOR
How should I be calling the PixelFormat functions?
