Public Member Functions | |
virtual | ~QgsAbstract3DSymbol ()=default |
virtual QgsAbstract3DSymbol * | clone () const =0 |
Returns a new instance of the symbol with the same settings. | |
virtual QList< Qgis::GeometryType > | compatibleGeometryTypes () const |
Returns the list of the vector layer geometry types which are compatible with this symbol. | |
QgsPropertyCollection & | dataDefinedProperties () |
Returns a reference to the symbol layer's property collection, used for data defined overrides. | |
const QgsPropertyCollection & | dataDefinedProperties () const |
Returns a reference to the symbol layer's property collection, used for data defined overrides. | |
virtual bool | exportGeometries (Qgs3DSceneExporter *exporter, Qt3DCore::QEntity *entity, const QString &objectNamePrefix) const |
Exports the geometries contained within the hierarchy of entity. | |
virtual void | readXml (const QDomElement &elem, const QgsReadWriteContext &context)=0 |
Reads symbol configuration from the given DOM element. | |
void | setDataDefinedProperties (const QgsPropertyCollection &collection) |
Sets the symbol layer's property collection, used for data defined overrides. | |
virtual void | setDefaultPropertiesFromLayer (const QgsVectorLayer *layer) |
Sets default properties for the symbol based on a layer's configuration. | |
virtual QString | type () const =0 |
