I have programmed cocoa for less than a year, so if I say something
stupid please bare with me. Of the programming I have done most of it
has been with QC apps. From what I remember the openGLContext was
added in 10.5 (and made me very excited).
In my 10.4 application I created a glcontext, set its view, and
rendered to it using a QCRenderer. Here is what that looked like,
please don't laugh at my ugly code, this is some of the first
objective-c I wrote:
//Create OpenGL context used to render the QCRenderers and attach it
to the rendering view
NSOpenGLPixelFormatAttribute attributes[] = {NSOpenGLPFAAccelerated,
NSOpenGLPFANoRecovery, NSOpenGLPFADoubleBuffer, NSOpenGLPFADepthSize,
24, 0};
glPixelFormat = [[NSOpenGLPixelFormat alloc]
initWithAttributes:attributes];
_glContext = [[NSOpenGLContext alloc] initWithFormat:glPixelFormat
shareContext:nil];
[_glContext setView:_renderView];
// Create QCRenderers from composition file
compositionPath = [bundle pathForResource:_compositionName
ofType:@"qtz"];
renderer = [[QCRenderer alloc] initWithOpenGLContext:_glContext
pixelFormat:glPixelFormat file:compositionPath];
This will allows you to flush your buffer, but doesn't produce nearly
as nice code as what the 10.5 stuff allows you to do.

Hi,
I build my app against 10.4 SDK. The compiler says that there are no
errors.
My app runs on Leopard very well. But on Tiger I get this error all
the time
and my app won't launch.

[MYQCView openGLContext] : selector not recognized [self = 0x1492fee0]

If I comment this line below
[[qcView openGLContext] flushBuffer];
my app launches and runs well, but of course I can't see the QCView
contents
properly. I have seen that this API is available in 10.5 and later.
Anyway
my compiler doesn't protest when I build my app against 10.4 SDK.
This a
part, how can I make this work on Tiger too? Any workaround?
Best Regards
