20 \brief An alternative canvas for a QwtPlot derived from QGLWidget
21
22 QwtPlotGLCanvas implements the very basics to act as canvas
23 inside of a QwtPlot widget. It might be extended to a full
24 featured alternative to QwtPlotCanvas in a future version of Qwt.
25
26 Even if QwtPlotGLCanvas is not derived from QFrame it imitates
27 its API. When using style sheets it supports the box model - beside
28 backgrounds with rounded borders.

30 \sa QwtPlot::setCanvas(), QwtPlotCanvas
31
32 \note With Qt4 you might want to use the QPaintEngine::OpenGL paint engine
33 ( see QGL::setPreferredPaintEngine() ). On a Linux test system
34 QPaintEngine::OpenGL2 shows very basic problems like translated
35 geometries.
