Drawing standard widgets using a custom paint engine

[pdolbey]

Something like

#IFDEF Q_OS_WIN
HGLRC rc = wglGetCurrentContext();
#ELSE
GLXContext rc = glXGetCurrentContext();
#ENDIF

#IFDEF Q_OS_WIN
HGLRC rc = wglGetCurrentContext();
#ELSE
GLXContext rc = glXGetCurrentContext();
#ENDIF

To copy to clipboard, switch view to plain text mode 

in the intializeGL() or paintGL() methods of a QGLWidget will probably get the necessary rendering contexts. I've proved the Windows leg first with an OpenCascade OpenGL viewer - the alternate piece is the logical extension for X11.
