If you create the widget, call its method to retrieve the context, then call setShareContext() with that pointer using your common context, that doesn't work?

Then the default created context has to be deleted and the shared context is assigned to every new widget, assuming setShareContext changes the widget context. But this sounds like a hack!Originally Posted by d_stranz

Don't know; I don't write explicit OpenGL code that much. I think your only option is to look at the implementation of QOpenGLWidget and then derive your own version from QWidget that lets you set the context externally instead of creating it by default. With luck you may be able to reuse a lot of the source code.But this sounds like a hack!
