Class: QgsRendererAbstractMetadata

class qgis.core.QgsRendererAbstractMetadata

Bases: sip.wrapper

Stores metadata about one renderer class.

Note

It’s necessary to implement createRenderer() function. In C++ you can use QgsRendererMetadata convenience class.

compatibleLayerTypes(self) → QgsRendererAbstractMetadata.LayerTypes

Returns flags indicating the types of layer the renderer is compatible with.

New in version 2.16.

createRenderer(self, elem: QDomElement, context: QgsReadWriteContext) → QgsFeatureRenderer

Returns new instance of the renderer given the DOM element. Returns None on error. Pure virtual function: must be implemented in derived classes. *

createRendererFromSld(self, elem: QDomElement, geomType: QgsWkbTypes.GeometryType) → QgsFeatureRenderer
createRendererWidget(self, layer: QgsVectorLayer, style: QgsStyle, oldRenderer: QgsFeatureRenderer) → QgsRendererWidget

Returns new instance of settings widget for the renderer. Returns None on error.

The oldRenderer argument may refer to previously used renderer (or it is None). If not None, it may be used to initialize GUI of the widget from the previous settings. The old renderer does not have to be of the same type as returned by createRenderer(). When using oldRenderer make sure to make a copy of it - it will be deleted afterwards.
