QOpenGLWidget not working with different context

Hi,

Problem is that, when I'm trying to move from QOpenGLWidget context inside class to extern QOpenGLContext is that whole screen is black. FPS counter and things like 3D coordinates working, so scene is working, problem is that rendered things are not drawed into widget.

Why Im moving to external? Problem was shared context wasnt working even with application attribute. QOpenGLShaderProgram said its not binded to correct context.

Code via pastebin.. Just one link, block of code from different classes: http://pastebin.com/Zha3QmKJ

Tried get help on IRC and forum, but seems no one knows where could be issue...

Thanks.
