Problem with QMainWindow +QGraphicsView and more than one QGLWidget

I have a problem in my Qt Application. I have a QMainWindow with a QGraphicsScene and a QGLWidget as viewport.

The problem comes when I want to show another QGLWidget with other OpenGL information (for example, the general view and another window with the Top view). In this 开发者_Python百科case, the two windows don't work good and have problems with the transformation Matrix in OpenGL. I try to use a shared widget (my first QGLWidget) and have the same context, but it fails anyway.

Any idea?

Thanks

This will be pretty difficult to without code. As a guess, perhaps you're not resetting your matrix operations to a known state before using them (see part 3 of the link)?
