I’m looking to do some OpenGL drawing in a window. I’ve already got a NSView subclass that I assign as the contentView in my NSWindow, and it works perfectly.
The problem I have now is that I want to make the OpenGL view part of a viewport in my window, i.e. I want to assign my OpenGL view as a subview of another NSView.
I’ve done this, but now each time I call [NSOpenGLContext setView: myCustomView] it fails with the message “invalid drawable”, which never occurred before. The only code difference here is that my window looks like:
NSWindow -> someView -> myOpenGLView
NSWindow -> myOpenGLView
like it was before.
I’ve scoured the net for some clue as to why this is happening, but all of the failure cases I’ve seen on Google seem to happen in the simpler case, whereas mine only fails on the more complex case.
Thanks in advance.
Sounds to me like you’re calling that when your view isn’t yet in a real window-server-sees-it window. But without your code it’s hard to say for sure, so PostYourCode.
