Abstract base class for all 2D vector feature renderers.
Base class for renderer settings widgets.
void setDockMode(bool dockMode) override
Set the widget in dock mode which tells the widget to emit panel widgets and not open dialogs.
virtual void setContext(const QgsSymbolWidgetContext &context)
Sets the context in which the renderer widget is shown, e.g., the associated map canvas and expressio...
virtual QgsFeatureRenderer * renderer()=0
Returns pointer to the renderer (no transfer of ownership)
virtual void disableSymbolLevels()
Disables symbol level modification on the widget.
virtual void setSymbolLevels(const QList< QgsLegendSymbolItem > &levels, bool enabled)
Sets the symbol levels for the renderer defined in the widget.
Symbol selector widget that can be used to select and build a symbol.
Contains settings which reflect the context in which a symbol (or renderer) widget is shown,...
Represents a vector layer which manages a vector based data sets.
