              I used QGLWidgets concurrently in one application, but it worked.
              Can you show example?

                      I have a problem in sharing a GLContext between two GLWidgets,
                      I have Dual monitor system which has got NVidia Graphics Card, Monitors are configured as Screen 0 & Screen 1 ( Separate X Screens). and i am trying to create one GLwidget on Screen 0 and the second GLWidget on Screen 1, if Both GLWidgets are at same screen i am able to share the context but if i create a second GLWidget on Screen 1 context is not sharing. Advance Thanks for any help.
