class QgsRendererWidget : QgsPanelWidget
{
%Docstring
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
%End
%TypeHeaderCode
#include "qgsrendererwidget.h"

%Docstring
return pointer to the renderer (no transfer of ownership)
:rtype: QgsFeatureRenderer
%End
void showSymbolLevelsDialog( QgsFeatureRenderer *r );
%Docstring
show a dialog with renderer's symbol level settings
%End
virtual void setContext( const QgsSymbolWidgetContext &context );

Sets the context in which the renderer widget is shown, e.g., the associated map canvas and expression contexts.
\param context symbol widget context

This method should be called whenever the renderer is actually set on the layer.

Emitted when expression context variables on the associated
vector layers have been changed. Will request the parent dialog
to re-synchronize with the variables.
