virtual ~QgsAbstract3DSymbol()=default
virtual void readXml(const QDomElement &elem, const QgsReadWriteContext &context)=0
Reads symbol configuration from the given DOM element.
virtual QString type() const =0
Returns identifier of symbol type. Each 3D symbol implementation should return a different type.
void setDataDefinedProperties(const QgsPropertyCollection &collection)
Sets 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 QgsAbstract3DSymbol * clone() const =0
Returns a new instance of the symbol with the same settings.
virtual void writeXml(QDomElement &elem, const QgsReadWriteContext &context) const =0
Writes symbol configuration to the given DOM element.
QgsPropertyCollection mDataDefinedProperties
Property
Data definable properties.
QgsPropertyCollection & dataDefinedProperties()
Returns a reference to the symbol layer's property collection, used for data defined overrides.
A grouped map of multiple QgsProperty objects, each referenced by a integer key value.
The class is used as a container of context for various read/write operations on other objects.
Represents a vector layer which manages a vector based data sets.
