in QGLWidget where i have to use Qt GL functions ..?
sorry instead of using QPainter i had written Qt GL functions ...

Note that widgets with the Qt::WA_PaintOnScreen widget attribute set and widgets that wrap an external application or controller are not supported. Examples are QGLWidget and QAxWidget.
fine ... stampede ... can u tell me is there any other option to embed a OpenGL widget ..?
i got this reference http://www.qtcentre.org/threads/1230...sScene-problem
