void writeXmlBaseProperties(QDomElement &elem, const QgsReadWriteContext &context) const
Writes common properties of this object to DOM element.
void readXmlBaseProperties(const QDomElement &elem, const QgsReadWriteContext &context)
Reads common properties of this object from DOM element.
void resolveReferences(const QgsProject &project) override
Resolves references to other objects - second phase of loading - after readXml()
void setLayer(QgsVectorLayer *layer)
Sets vector layer associated with the renderer.
void copyBaseProperties(QgsAbstractVectorLayer3DRenderer *r) const
Copies common properties of this object to another object.
QgsVectorLayer * layer() const
Returns vector layer associated with the renderer.
Encapsulates a QGIS project, including sets of map layers and their styles, layouts,...
Definition qgsproject.h:107
Q_INVOKABLE QgsMapLayer * mapLayer(const QString &layerId) const
Retrieve a pointer to a registered layer by layer ID.
The class is used as a container of context for various read/write operations on other objects.
void readXml(const QDomElement &elem)
Reads content of the object from XML.
void writeXml(QDomElement &elem) const
Writes content of the object to XML.
Represents a vector layer which manages a vector based data sets.
_LayerRef< QgsMapLayer > QgsMapLayerRef
QPointer< TYPE > layer
Weak pointer to map layer.
void setLayer(TYPE *l)
Sets the reference to point to a specified layer.
QString layerId
Original layer ID.
