addFeatureV2(self, layer: QgsVectorLayer | None, defaultValues: Dict[int, Any], defaultGeometry: QgsGeometry, context: QgsVectorLayerToolsContext)

This method calls the addFeature method of the backend QgsVectorLayerTools

Parameters:

  • layer (Optional[QgsVectorLayer]) – The layer to which the feature should be added

  • defaultValues (Dict[int) – Default values for the feature to add

  • defaultGeometry (QgsGeometry) – A default geometry to add to the feature

  • context (QgsVectorLayerToolsContext) -> (bool) – A context object to be used for e.g. to calculate feature expression-based values (since QGIS 3.38)

Returns:

  • True in case of success, False if the operation failed/was aborted

  • feature: A pointer to the feature

childEvent(self, a0: QChildEvent | None)
connectNotify(self, signal: QMetaMethod)
copyMoveFeatures(self, layer: QgsVectorLayer | None, request: QgsFeatureRequest, dx: float = 0, dy: float = 0, errorMsg: str | None | None = '', topologicalEditing: bool = False, topologicalLayer: QgsVectorLayer | None = None, childrenInfoMsg: str | None | None = '') → bool
Parameters:

  • layer (Optional[QgsVectorLayer])

  • request (QgsFeatureRequest)

  • dx (float = 0)

  • dy (float = 0)

  • errorMsg (Optional[Optional[str]] = '')

  • topologicalEditing (bool = False)

  • topologicalLayer (Optional[QgsVectorLayer] = None)

  • childrenInfoMsg (Optional[Optional[str]] = '')

Return type:

bool
