The class is used as a container of context for various read/write operations on other objects...
virtual QDomElement save(QDomDocument &doc, const QgsReadWriteContext &context)
store renderer info to XML element
Container of fields for a vector layer.
Definition: qgsfields.h:42
The feature class encapsulates a single feature including its id, geometry and a list of field/values...
Definition: qgsfeature.h:62
virtual QSet< QString > usedAttributes(const QgsRenderContext &context) const =0
Return a list of attributes required by this renderer.
QList< QgsSymbol * > QgsSymbolList

#define SIP_FACTORY
Definition: qgis_sip.h:69
A paint effect which draws a glow outside of a picture.
virtual QgsSymbolList symbols(QgsRenderContext &context)
Returns list of symbols used by the renderer.
Definition: qgsrenderer.h:266
virtual QgsSymbol * symbolForFeature(QgsFeature &feature, QgsRenderContext &context)=0
To be overridden.
Contains information about the context of a rendering operation.
virtual void startRender(QgsRenderContext &context, const QgsFields &fields)
Must be called when a new render cycle is started.
Definition: qgsrenderer.cpp:92
virtual void stopRender(QgsRenderContext &context)
Must be called when a render cycle has finished, to allow the renderer to clean up.
virtual QgsFeatureRenderer * clone() const =0
Create a deep copy of this renderer.
