◆ clone()

QgsSymbolLayerV2 * QgsGeometryGeneratorSymbolLayerV2::clone ( ) const

overridevirtual

Shall be reimplemented by subclasses to create a deep copy of the instance.

Implements QgsSymbolLayerV2.

Definition at line 107 of file qgsgeometrygeneratorsymbollayerv2.cpp.

◆ create()

◆ drawPreviewIcon()

void QgsGeometryGeneratorSymbolLayerV2::drawPreviewIcon	(	QgsSymbolV2RenderContext &	context,
		QSize	size
	)

overridevirtual

Implements QgsSymbolLayerV2.

Definition at line 145 of file qgsgeometrygeneratorsymbollayerv2.cpp.

◆ geometryExpression()

QString QgsGeometryGeneratorSymbolLayerV2::geometryExpression ( ) const

inline

Get the expression to generate this geometry.

Definition at line 67 of file qgsgeometrygeneratorsymbollayerv2.h.

◆ isCompatibleWithSymbol()

bool QgsGeometryGeneratorSymbolLayerV2::isCompatibleWithSymbol ( QgsSymbolV2 * symbol ) const

overridevirtual

Will always return true.

This is a hybrid layer, it constructs its own geometry so it does not care about the geometry of its parents.

Reimplemented from QgsSymbolLayerV2.

Definition at line 186 of file qgsgeometrygeneratorsymbollayerv2.cpp.

◆ layerType()

QString QgsGeometryGeneratorSymbolLayerV2::layerType ( ) const

overridevirtual

Returns a string that represents this layer type.

Used for serialization. Should match with the string used to register this symbol layer in the registry.

Implements QgsSymbolLayerV2.

Definition at line 63 of file qgsgeometrygeneratorsymbollayerv2.cpp.

◆ properties()

QgsStringMap QgsGeometryGeneratorSymbolLayerV2::properties ( ) const

overridevirtual

Should be reimplemented by subclasses to return a string map that contains the configuration information for the symbol layer.

This is used to serialize a symbol layer perstistently.

Implements QgsSymbolLayerV2.

Definition at line 125 of file qgsgeometrygeneratorsymbollayerv2.cpp.

◆ render()

void QgsGeometryGeneratorSymbolLayerV2::render ( QgsSymbolV2RenderContext & context )

virtual

Will render this symbol layer using the context.

In comparison to other symbols there is no geometry passed in, since the geometry will be created based on information from the context which contains a QgsRenderContext which in turn contains an expression context which is available to the evaluated expression.

Parameters

context The rendering context which will be used to render and to construct a geometry.

Definition at line 191 of file qgsgeometrygeneratorsymbollayerv2.cpp.

◆ setColor()

void QgsGeometryGeneratorSymbolLayerV2::setColor ( const QColor & color )

overridevirtual

The fill color.

◆ setSubSymbol()

bool QgsGeometryGeneratorSymbolLayerV2::setSubSymbol ( QgsSymbolV2 * symbol )

overridevirtual

set layer's subsymbol. takes ownership of the passed symbol

Reimplemented from QgsSymbolLayerV2.

Definition at line 156 of file qgsgeometrygeneratorsymbollayerv2.cpp.

◆ setSymbolType()

void QgsGeometryGeneratorSymbolLayerV2::setSymbolType ( QgsSymbolV2::SymbolType symbolType )

Set the type of symbol which should be created.

Should match with the return type of the expression.

Parameters

symbolType The symbol type which shall be used below this symbol.

◆ startRender()

void QgsGeometryGeneratorSymbolLayerV2::startRender ( QgsSymbolV2RenderContext & context )

overridevirtual

Implements QgsSymbolLayerV2.

void QgsGeometryGeneratorSymbolLayerV2::stopRender ( QgsSymbolV2RenderContext & context )

overridevirtual

Implements QgsSymbolLayerV2.

Definition at line 101 of file qgsgeometrygeneratorsymbollayerv2.cpp.

◆ subSymbol()

virtual QgsSymbolV2* QgsGeometryGeneratorSymbolLayerV2::subSymbol ( )

inlineoverridevirtual

Reimplemented from QgsSymbolLayerV2.

Definition at line 69 of file qgsgeometrygeneratorsymbollayerv2.h.

◆ symbolType()

QgsSymbolV2::SymbolType QgsGeometryGeneratorSymbolLayerV2::symbolType ( ) const

inline

Access the symbol type.

This defines the type of geometry that is created by this generator.

Returns: Symbol type

Definition at line 47 of file qgsgeometrygeneratorsymbollayerv2.h.

◆ usedAttributes()

QSet< QString > QgsGeometryGeneratorSymbolLayerV2::usedAttributes ( ) const

overridevirtual

Returns the set of attributes referenced by the layer.
