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.

QObject

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

pyqtSignal(*types, name: str = …, revision: int = …, arguments: Sequence = …) -> PYQT_SIGNAL

types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.

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]
