Methods

`algorithmForIndex`	Returns the algorithm at the specified tree view index, or `None` if the index does not correspond to an algorithm.
`filters`	Returns the current filters controlling the view's contents.
`selectedAlgorithm`	Returns the currently selected algorithm in the tree view, or `None` if no algorithm is currently selected.
`setFilterString`	Sets a filter string, used to filter out the contents of the view to matching algorithms.
`setFilters`	Sets filters controlling the view's contents.
`setInPlaceLayer`	Sets the vector layer for the in-place algorithms
`setRegistry`	Sets the processing registry associated with the view.
`setToolboxProxyModel`	Sets the toolbox proxy model used to drive the view.

class qgis.gui.QgsProcessingToolboxTreeView[source]¶

Bases: QTreeView

__init__(parent: QWidget | None = None, registry: QgsProcessingRegistry | None = None, recentLog: QgsProcessingRecentAlgorithmLog | None = None, favoriteManager: QgsProcessingFavoriteAlgorithmManager | None = None)

Constructor for QgsProcessingToolboxTreeView, with the specified parent widget.

If registry is set, then the view will automatically be populated with algorithms and providers from the registry. Otherwise, users must manually call setRegistry() to associate a registry with the view.

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

If favoriteManager is specified then it will be used to create a “Favorites” top level group containing favorite algorithms. Since QGIS 3.40

Parameters:

parent (Optional[QWidget] = None)
registry (Optional[QgsProcessingRegistry] = None)
recentLog (Optional[QgsProcessingRecentAlgorithmLog] = None)
favoriteManager (Optional[QgsProcessingFavoriteAlgorithmManager] = None)

algorithmForIndex(self, index: QModelIndex) → QgsProcessingAlgorithm | None[source]¶

Returns the algorithm at the specified tree view index, or None if the index does not correspond to an algorithm.

Parameters:: index (QModelIndex)
Return type:: Optional[QgsProcessingAlgorithm]

filters(self) → QgsProcessingToolboxProxyModel.Filters[source]¶

Returns the current filters controlling the view’s contents.
