Programmatically adding OpenGL view to window

Same issue here

Looks like we're trying to figure out the same thing.

I've got a simple project where I just want a window with an NSOpenGLView covering the entire window contentView colored blue and a triangle displayed. The window displays, but I see no NSOpenGLView content.

I've got my project here: http://www.2shared.com/file/XEUDnkaJ/binaryinsomnia.html

Hopefully, I'm not threadjacking. I think we, basically, have the same question.

Thanks!

BTW, I used the code found in https://github.com/beelsebob/Cocoa-GL-Tutorial to help me get started on my as-of-yet-flawed project.

 

That is not a simple project if you're starting out with Cocoa/OpenGL integration.

Try my sample project here which just displays a black background and a red triangle:
http://code.google.com/p/kaincode/source/browse/#svn/trunk/CocoaGL

Then build upon that slowly.

Assuming you're setting up the 3.2 vs 2.x check via NSOpenGLPixelFormat, its initWithAttributes: will return nil if it can't initialize with the attributes given, so you could create a method to check for that and revert to 2.x settings if the 3.2 attributes fail.

An OpenGL view is an NSView, so it's added to a window just like any other view: create the window, create the OpenGL view, and set it as the window's content view, then show the window.

 

Thanks!

I'm finding that this is the case, actually.

Thanks for the link to your code! It will definitely help me.

 

If the NSOpenGLView is to be the sole content in the window then:

Code:

window.content = openGLView; // or [window setContent:openGLView];

If there is to be other content in the window, then you'd added it as subview of a view already in the window.

Code:

[viewAlreadyInWindow addSubview:openGLView];
