The class is used as a container of context for various read/write operations on other objects...
Base class for all renderers that may to participate in 3D view.
virtual Qt3DCore::QEntity * createEntity(const Qgs3DMapSettings &map) const =0
Returns a 3D entity that will be used to show renderer&#39;s data in 3D scene.
3 Definition of the world
3 Abstract base class for 3D symbols that are used by VectorLayer3DRenderer objects.
virtual void writeXml(QDomElement &elem, const QgsReadWriteContext &context) const =0
Writes renderer&#39;s properties to given XML element.
#define SIP_SKIP
Definition: qgis_sip.h:126
QString type() const override
Returns unique identifier of the renderer class (used to identify subclass)
#define SIP_TRANSFER
Definition: qgis_sip.h:36
#define SIP_FACTORY
Definition: qgis_sip.h:76
3D renderer that renders all features of a vector layer with the same 3D symbol.
virtual void readXml(const QDomElement &elem, const QgsReadWriteContext &context)=0
Reads renderer&#39;s properties from given XML element.
3 Base class for 3D renderers that are based on vector layers.
Metadata for vector layer 3D renderer to allow creation of its instances from XML.
virtual QgsAbstract3DRenderer * clone() const =0
Returns a cloned instance.
Base metadata class for 3D renderers.
Represents a vector layer which manages a vector based data sets.
virtual QgsAbstract3DRenderer * createRenderer(QDomElement &elem, const QgsReadWriteContext &context)=0
Returns new instance of the renderer given the DOM element.
