[docs]class GraphicsLayoutWidget(GraphicsView): """ Convenience class consisting of a :class:`GraphicsView <pyqtgraph.GraphicsView>` with a single :class:`GraphicsLayout <pyqtgraph.GraphicsLayout>` as its central item. This widget is an easy starting point for generating multi-panel figures.

If the widget has no parent, then it will be shown inside a new window. size (width, height) tuple. Optionally resize the widget. Note: if this widget is placed inside a layout, then this argument has no effect. title (str or None) If specified, then set the window title for this widget. kargs All extra arguments are passed to :meth:`GraphicsLayout.__init__ <pyqtgraph.GraphicsLayout.__init__>` ========= ================================================================= This class wraps several methods from its internal GraphicsLayout: :func:`nextRow <pyqtgraph.GraphicsLayout.nextRow>` :func:`nextColumn <pyqtgraph.GraphicsLayout.nextColumn>` :func:`addPlot <pyqtgraph.GraphicsLayout.addPlot>` :func:`addViewBox <pyqtgraph.GraphicsLayout.addViewBox>` :func:`addItem <pyqtgraph.GraphicsLayout.addItem>` :func:`getItem <pyqtgraph.GraphicsLayout.getItem>` :func:`addLabel <pyqtgraph.GraphicsLayout.addLabel>` :func:`addLayout <pyqtgraph.GraphicsLayout.addLayout>` :func:`removeItem <pyqtgraph.GraphicsLayout.removeItem>` :func:`itemIndex <pyqtgraph.GraphicsLayout.itemIndex>` :func:`clear <pyqtgraph.GraphicsLayout.clear>` """
