◆ compatibleLayerTypes()

QgsRendererAbstractMetadata::LayerTypes QgsRendererMetadata::compatibleLayerTypes ( ) const

inlineoverridevirtual

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

Reimplemented from QgsRendererAbstractMetadata.

Definition at line 196 of file qgsrendererregistry.h.

◆ createFromSldFunction()

QgsRendererCreateFromSldFunc QgsRendererMetadata::createFromSldFunction ( ) const

inline

Note: not available in Python bindings

Definition at line 187 of file qgsrendererregistry.h.

◆ createRenderer()

QgsFeatureRenderer * QgsRendererMetadata::createRenderer	(	QDomElement &	elem,
		const QgsReadWriteContext &	context
	)

inlineoverridevirtual

Returns new instance of the renderer given the DOM element.

Returns nullptr on error. Pure virtual function: must be implemented in derived classes.

Implements QgsRendererAbstractMetadata.

Definition at line 179 of file qgsrendererregistry.h.

◆ createRendererFromSld()

QgsFeatureRenderer * QgsRendererMetadata::createRendererFromSld	(	QDomElement &	elem,
		Qgis::GeometryType	geomType
	)

inlineoverridevirtual

Returns a new instance of the renderer, converted from an SLD XML element.

Reimplemented from QgsRendererAbstractMetadata.

Definition at line 183 of file qgsrendererregistry.h.

◆ createRendererWidget()

QgsRendererWidget * QgsRendererMetadata::createRendererWidget	(	QgsVectorLayer *	layer,
		QgsStyle *	style,
		QgsFeatureRenderer *	oldRenderer
	)

inlineoverridevirtual

Returns new instance of settings widget for the renderer.

Returns nullptr on error.

The oldRenderer argument may refer to previously used renderer (or it is nullptr). If not nullptr, 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().

Reimplemented from QgsRendererAbstractMetadata.

Definition at line 181 of file qgsrendererregistry.h.

◆ setWidgetFunction()

void QgsRendererMetadata::setWidgetFunction ( QgsRendererWidgetFunc f )
