Class: QgsRendererWidget

class qgis.gui.QgsRendererWidget

Bases: qgis._gui.QgsPanelWidget

Base class for renderer settings widgets

WORKFLOW: - open renderer dialog with some RENDERER (never null!) - find out which widget to use - instantiate it and set in stacked widget - on any change of renderer type, create some default (dummy?) version and change the stacked widget - when clicked OK/Apply, get the renderer from active widget and clone it for the layer
