Class: QgsProcessingToolboxModel¶

class qgis.gui.QgsProcessingToolboxModel(parent: QObject = None, registry: QgsProcessingRegistry = None, recentLog: QgsProcessingRecentAlgorithmLog = None)¶

Bases: PyQt5.QtCore.QAbstractItemModel

Constructor for QgsProcessingToolboxModel, with the given parent object.

If registry is specified then the model will show providers and algorithms from the given registry. If no registry is specified, then the processing registry attached to QgsApplication.processingRegistry() will be used by the model.

If recentLog is specified then it will be used to create a “Recently used” top level group containing recently used algorithms.

A model for providers and algorithms shown within the Processing toolbox.

See QgsProcessingToolboxProxyModel for a sorted, filterable version of this model.

New in version 3.4: Enums
