Class: QgsSymbolLayerAbstractMetadata¶

class qgis.core.QgsSymbolLayerAbstractMetadata¶

Bases: sip.wrapper

Stores metadata about one symbol layer class.

Note

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

Enums

Methods

`createSymbolLayer`	Create a symbol layer of this type given the map of properties.
`createSymbolLayerFromSld`	Create a symbol layer of this type given the map of properties.
`createSymbolLayerWidget`	Create widget for symbol layer of this type.
`name`
`resolvePaths`	Resolve paths in symbol layer’s properties (if there are any paths).
`type`
`visibleName`

Signals

Attributes

createSymbolLayer(self, map: Dict[str, str]) → QgsSymbolLayer¶: Create a symbol layer of this type given the map of properties.

createSymbolLayerFromSld(self, QDomElement) → QgsSymbolLayer¶: Create a symbol layer of this type given the map of properties.

createSymbolLayerWidget(self, QgsVectorLayer) → QgsSymbolLayerWidget¶: Create widget for symbol layer of this type. Can return None if there’s no GUI

resolvePaths(self, properties: Dict[str, str], pathResolver: QgsPathResolver, saving: bool)¶: Resolve paths in symbol layer’s properties (if there are any paths). When saving is True, paths are converted from absolute to relative, when saving is False, paths are converted from relative to absolute. This ensures that paths in project files can be relative, but in symbol layer instances the paths are always absolute
