Title: OpenGL binding for Qt
Post by: Ocye on December 13, 2014, 10:26:37 am

I just realized that OpenGL works with Qt which is great news for my project. I wonder how far the implementation has been done. Actually, vertex buffer objects are not drawn (I don't get any OpenGL error). Is it a bug or not yet implemented?

Nevertheless, thanks a lot!

PS: It's not working yet on darwin:

I assume this is due to glqtcontext assumes X11 display which is not darwin's native display. I can't find any replacement for darwin in the respective qt bindings, though.

Whatever the reason is it looks like OpenGL binding for Qt is not finished yet. Any schedule?
