Detailed Description

3 Abstract base class for 3D symbols that are used by VectorLayer3DRenderer objects.

3D symbol objects define appearance of GIS data.

Member Function Documentation

◆ clone()

virtual QgsAbstract3DSymbol* QgsAbstract3DSymbol::clone ( ) const
pure virtual

Returns a new instance of the symbol with the same settings.

Implemented in QgsMesh3DSymbol, QgsPoint3DSymbol, QgsPolygon3DSymbol, and QgsLine3DSymbol.

◆ dataDefinedProperties() [1/2]

QgsPropertyCollection& QgsAbstract3DSymbol::dataDefinedProperties ( )
inline

Returns a reference to the symbol layer's property collection, used for data defined overrides.

Definition at line 67 of file qgsabstract3dsymbol.h.

◆ dataDefinedProperties() [2/2]

const QgsPropertyCollection& QgsAbstract3DSymbol::dataDefinedProperties ( ) const
inline

Returns a reference to the symbol layer's property collection, used for data defined overrides.

Definition at line 70 of file qgsabstract3dsymbol.h.

◆ propertyDefinitions()

const QgsPropertiesDefinition & QgsAbstract3DSymbol::propertyDefinitions ( )
static

Returns the symbol layer property definitions.

Definition at line 22 of file qgsabstract3dsymbol.cpp.

◆ readXml()

virtual void QgsAbstract3DSymbol::readXml ( const QDomElement &  elem,
const QgsReadWriteContext context 
)
pure virtual

Reads symbol configuration from the given DOM element.

Implemented in QgsMesh3DSymbol, QgsPoint3DSymbol, QgsPolygon3DSymbol, and QgsLine3DSymbol.

◆ setDataDefinedProperties()

void QgsAbstract3DSymbol::setDataDefinedProperties ( const QgsPropertyCollection collection)
inline

Sets the symbol layer's property collection, used for data defined overrides.

Definition at line 73 of file qgsabstract3dsymbol.h.

◆ type()

virtual QString QgsAbstract3DSymbol::type ( ) const
pure virtual

Returns identifier of symbol type. Each 3D symbol implementation should return a different type.

Implemented in QgsMesh3DSymbol, QgsPoint3DSymbol, QgsPolygon3DSymbol, and QgsLine3DSymbol.

◆ writeXml()

virtual void QgsAbstract3DSymbol::writeXml ( QDomElement &  elem,
const QgsReadWriteContext context 
) const
pure virtual

Writes symbol configuration to the given DOM element.

Implemented in QgsMesh3DSymbol, QgsPoint3DSymbol, QgsPolygon3DSymbol, and QgsLine3DSymbol.
