RoleAlgorithmId	Algorithm ID, for algorithm nodes.
RoleAlgorithmName	Untranslated algorithm name, for algorithm nodes.
RoleAlgorithmShortDescription	Short algorithm description, for algorithm nodes.
RoleAlgorithmTags	List of algorithm tags, for algorithm nodes.
RoleProviderFlags	Returns the node's provider flags.

Constructor & Destructor Documentation

◆ QgsProcessingToolboxModel()

QgsProcessingToolboxModel::QgsProcessingToolboxModel	(	QObject *	parent = `nullptr`,
		QgsProcessingRegistry *	registry = `nullptr`,
		QgsProcessingRecentAlgorithmLog *	recentLog = `nullptr`
	)

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.
