       An alternative canvas for a QwtPlot derived from QGLWidget.

       QwtPlotGLCanvas implements the very basics to act as canvas inside of a QwtPlot widget. It might be
       extended to a full featured alternative to QwtPlotCanvas in a future version of Qwt.

       Even if QwtPlotGLCanvas is not derived from QFrame it imitates its API. When using style sheets it
       supports the box model - beside backgrounds with rounded borders.

       Seealso:QwtPlot::setCanvas(), QwtPlotCanvasNote:
           With Qt4 you might want to use the QPaintEngine::OpenGL paint engine ( see
           QGL::setPreferredPaintEngine() ). On a Linux test system QPaintEngine::OpenGL2 shows very basic
           problems like translated geometries.

enumQwtPlotGLCanvas::Shadow
       Frame shadow. Unfortunately it is not possible to use QFrame::Shadow as a property of a widget that is
       not derived from QFrame. The following enum is made for the designer only. It is safe to use
       QFrame::Shadow instead.

       EnumeratorPlain  QFrame::Plain.

       Raised QFrame::Raised.

       Sunken QFrame::Sunken.

   enumQwtPlotGLCanvas::Shape
       Frame  shape. Unfortunately it is not possible to use QFrame::Shape as a property of a widget that is not
       derived from QFrame. The following enum is made for the designer only. It is safe to  use  QFrame::Shadow
       instead.

       Note:
           QFrame::StyledPanel and QFrame::WinPanel are unsupported and will be displayed as QFrame::Panel.
