QWindow/QSurface, which internally uses NSOpenGLContext and afterwards we query for the current context using aglGetCurrentContext() which is incompatible. We should just use QOpenGLContext::currentContext() instead. 583961 2 133004 zeno 2012-03-21 03:42:17 -0700 Created attachment 133004 patch for review. 583964 3 133004 kenneth 2012-03-21 03:51:31 -0700 Comment on attachment 133004 patch for review.
