Detailed Description¶
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.

Member Enumeration Documentation¶
enum QwtPlotGLCanvas::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.Enumerator
- Plain
- QFrame::Plain.
- Raised
- QFrame::Raised.
- Sunken
- QFrame::Sunken.
enum QwtPlotGLCanvas::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:
