Class: QgsProcessingRecentAlgorithmLog

class qgis.gui.QgsProcessingRecentAlgorithmLog(parent: QObject = None)

Bases: PyQt5.QtCore.QObject

Constructor for QgsProcessingRecentAlgorithmLog, with the specified parent object.

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.


Not stable API

New in version 3.4.




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

childEvent(self, QChildEvent)
connectNotify(self, QMetaMethod)
customEvent(self, QEvent)
disconnectNotify(self, QMetaMethod)
isSignalConnected(self, QMetaMethod) → bool
push(self, id: str)

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.


id (str) –

receivers(self, PYQT_SIGNAL) → int
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


sender(self) → QObject
senderSignalIndex(self) → int
timerEvent(self, QTimerEvent)
