Class: QgsProcessingParameterMeshDatasetGroups

class qgis.core.QgsProcessingParameterMeshDatasetGroups

Bases: QgsProcessingParameterDefinition

A parameter for processing algorithms that need a list of mesh dataset groups.

A valid value for this parameter is a list (QVariantList) of dataset groups index in the mesh layer scope Dataset group index can be evaluated with the method valueAsDatasetGroup()

Note

This parameter is dependent on a mesh layer parameter (see QgsProcessingParameterMeshLayer)

New in version 3.18.

QgsProcessingParameterMeshDatasetGroups(name: str, description: str = ‘’, meshLayerParameterName: str = ‘’, supportedDataType: object = QSet<int>(), optional: bool = False) Constructor

Parameters

  • name – name of the parameter

  • description – description of the parameter

  • meshLayerParameterName – name of the associated mesh layer parameter

  • supportedDataType – a set of QgsMeshDatasetGroupMetadata.DataType values for data types supported by the parameter

  • optional – whether the parameter is optional
