        **Bases:** :class:`GraphicsItem <pyqtgraph.GraphicsItem>`, :class:`QtWidgets.QGraphicsWidget`
        
        Extends QGraphicsWidget with several helpful methods and workarounds for PyQt bugs. 
        Most of the extra functionality is inherited from :class:`GraphicsItem <pyqtgraph.GraphicsItem>`.
