I went through and commented out calls from drawRect: into my own code, so I'm
not doing anything when drawRect: is called. I've also commented out all calls
to setNeedsDisplay: and setNeedsDisplayInRect:. A lot of the drawing (OpenGL)
in the app is triggered by timers so I've prevented the timers starting. The
timers weren't firing anyway as they're not on the modal event loop, but just
to be certain. I've commented out the few places I was adding observers
directly. All to no avail, the leak is still happening.
I use Cocoa at fairly basic level because the Cocoa stuff is the back end to a
C++ GUI framework. I'm not doing anything particularly fancy, such as KVO.
Here's how I run the modal loop just in case:
NSWindow* macWindow = ( NSWindow* )theDialog.GetNativeWindow();
UCMacWindowImp* windowImp = ( UCMacWindowImp* )theDialog.GetImplementation();
if ( ( macWindow != nil ) && ( windowImp != NULL ) )
{
NSModalSession modalSession;
// Need to retain then release window because [NSApp endModalSession] seems
to expect
// the window to still be around on 10.4 and 10.5
[macWindow retain];
modalSession = [NSApp beginModalSessionForWindow:macWindow];
windowImp->SetModalSession( modalSession );
for (;;)
{
if ([NSApp runModalSession:modalSession] != NSRunContinuesResponse)
break;
}
[NSApp endModalSession:modalSession];
[macWindow release];
}
Thanks for your help.
Regards,
Jo Meder
