I've tried to implement this method but I stumbled on a problem.  The thing is, my internal widget 
inherits both QGLWidget and an attribute class which I named MdiWindowProperties.  Yet, 
QMdiSubWindow::activeSubWindow() returns a pointer to a QWidget object.  So the only class which I 
believe is available through a dynamic_cast<> is QGLWidget and not MdiWindowProperties. 

So, can anyone help?
