Attributes

capabilities(self) → QgsFeatureRenderer.Capabilities

clone(self) → QgsSingleSymbolRenderer

convertFromRenderer(renderer: QgsFeatureRenderer) → QgsSingleSymbolRenderer

creates a QgsSingleSymbolRenderer from an existing renderer.

Returns:a new renderer if the conversion was possible, otherwise 0.

New in version 2.5.

convertSymbolRotation()

convertSymbolSizeScale()

copyRendererData()

create(element: QDomElement, context: QgsReadWriteContext) → QgsFeatureRenderer

create renderer from XML element

createFromSld(element: QDomElement, geomType: QgsWkbTypes.GeometryType) → QgsFeatureRenderer

dataDefinedSizeLegend(self) → QgsDataDefinedSizeLegend

Returns configuration of appearance of legend when using data-defined size for marker symbols. Will return null if the functionality is disabled.

New in version 3.0.

dump(self) → str

legendKeysForFeature(self, feature: QgsFeature, context: QgsRenderContext) → Set[str]

legendSymbolItems(self) → object

originalSymbolForFeature(self, feature: QgsFeature, context: QgsRenderContext) → QgsSymbol

renderFeatureWithSymbol()

renderVertexMarker()

renderVertexMarkerPolygon()

renderVertexMarkerPolyline()

save(self, doc: QDomDocument, context: QgsReadWriteContext) → QDomElement

setDataDefinedSizeLegend(self, settings: QgsDataDefinedSizeLegend)

Configures appearance of legend when renderer is configured to use data-defined size for marker symbols. This allows configuring which values (symbol sizes) should be shown in the legend, whether to display different symbol sizes collapsed in one legend node or separated across multiple legend nodes etc.

When renderer does not use data-defined size or does not use marker symbols, these settings will be ignored. Takes ownership of the passed settings objects. Null pointer is a valid input that disables data-defined size legend.

New in version 3.0.
