Class: QgsProcessingRecentAlgorithmLog

A log for tracking recently used processing algorithms.

QgsProcessingRecentAlgorithmLog is not usually directly created, instead use the instance accessible through QgsGui.processingRecentAlgorithmLog().

The log contents are saved and restored via QgsSettings.

Note

Not stable API

Added in version 3.4.

Methods

push	Pushes the algorithm with matching id to the top of the recently used algorithm list.
recentAlgorithmIds	Returns a list of the IDs of recently used processing algorithms, where the first item in the list is the most recently used algorithm.

Signals

changed

Emitted when the list of recently used algorithms is changed, e.g. when a new algorithm ID is pushed to the list (see push()).

class qgis.gui.QgsProcessingRecentAlgorithmLog

Bases: QObject

__init__(parent: QObject | None = None)

Constructor for QgsProcessingRecentAlgorithmLog, with the specified parent object.

Parameters:

parent (Optional[QObject] = None)

signal changed

Emitted when the list of recently used algorithms is changed, e.g. when a new algorithm ID is pushed to the list (see push()).

push(self, id: str | None)

Pushes the algorithm with matching id to the top of the recently used algorithm list.

If this changes the list of recent algorithm IDs then the changed() signal will be emitted.

Parameters:

id (Optional[str])

recentAlgorithmIds(self) → List[str]

Returns a list of the IDs of recently used processing algorithms, where the first item in the list is the most recently used algorithm.

Return type:

List[str]
