Class: QgsProcessingRecentAlgorithmLog

class qgis.gui.QgsProcessingRecentAlgorithmLog

Bases: PyQt5.QtCore.QObject

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

New in version 3.4.

QgsProcessingRecentAlgorithmLog(parent: QObject = None) Constructor for QgsProcessingRecentAlgorithmLog, with the specified parent object.

Methods

childEvent

connectNotify

customEvent

disconnectNotify

isSignalConnected

push

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

receivers

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.

sender

senderSignalIndex

timerEvent

Signals

changed

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

Parameters
  • name (str = ...) –

  • revision (int = ...) –

  • arguments (Sequence = ...) –

Return type

PYQT_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.

Parameters

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

List[str]

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