QT 5.1: Pure desktop OpenGL in widget?

[semos]

Hi,
I'am currently working on game editor: I need 3D scene combined with system GUI. Something like my previous editor based on QT 4.x: www.youtube.com/watch?v=__EGoLDSBv8.

But Qt 5.1 have different approach to OpenGL. As I understood, it is recommended to use QWindow. But it is just a window, I need widget (QGLWidget), which is deprecated. Why? It's there different way to have opengl viewport in widget?

Second question is about Angle and OpenGL|ES. For my editor, I preffer pure desktop OpenGL, how can I force QT to use it?

Thanks!
