My software "adopts" qtz files as plugins using
QCRenderer. At startup, I must create an
NSOpenGLContext so that I can get information
about the plugins, i.e., the parameter names, etc.
But I'm receiving a handful of bug reports where
the creation of the pixel format for the context
fails -- this is when calling
NSOpenGLPixelFormat. Problem is, I can't recreate
this bug on any computer in my possession.
(This happens only on Lion; I have no bug reports for Snow Leopard on this.)
The code is pretty simple, and taken from Apple examples:
static NSOpenGLPixelFormatAttribute sOpenGLAttributes[] = {
NSOpenGLPFANoRecovery,
NSOpenGLPFAAccelerated,
NSOpenGLPFADoubleBuffer,
NSOpenGLPFAFullScreen,
NSOpenGLPFAScreenMask,
(NSOpenGLPixelFormatAttribute)
CGDisplayIDToOpenGLDisplayMask(kCGDirectMainDisplay),
NSOpenGLPFADepthSize, (NSOpenGLPixelFormatAttribute) 32,
(NSOpenGLPixelFormatAttribute) 0
};
mQCFormat = [[NSOpenGLPixelFormat alloc] initWithAttributes:sOpenGLAttributes];
Can anyone tell me why this might be failing?
Obviously, I've got a "no recovery" in there so
if the system can't create the format, I got
nuthin'.
Is NSOpenGLPFAFullScreen the problem?
Thanks in advance for any insights.
Best Wishes,
Mark
