Class: QgsMapLayerAction

class qgis.gui.QgsMapLayerAction

Bases: PyQt5.QtWidgets.QAction

An action which can run on map layers The class can be used in two manners: * by instantiating it and connecting to its signals to perform an action * by subclassing and reimplementing its method (only since QGIS 3.18.2)

QgsMapLayerAction(name: str, parent: QObject, targets: Union[Qgis.MapLayerActionTargets, Qgis.MapLayerActionTarget] = Qgis.MapLayerActionTarget.AllActions, icon: QIcon = QIcon(), flags: Union[Qgis.MapLayerActionFlags, Qgis.MapLayerActionFlag] = Qgis.MapLayerActionFlags()) Creates a map layer action which can run on any layer

Note

using AllActions as a target probably does not make a lot of sense. This default action was settled for API compatibility reasons.

QgsMapLayerAction(name: str, parent: QObject, layer: QgsMapLayer, targets: Union[Qgis.MapLayerActionTargets, Qgis.MapLayerActionTarget] = Qgis.MapLayerActionTarget.AllActions, icon: QIcon = QIcon(), flags: Union[Qgis.MapLayerActionFlags, Qgis.MapLayerActionFlag] = Qgis.MapLayerActionFlags()) Creates a map layer action which can run only on a specific layer

QgsMapLayerAction(name: str, parent: QObject, layerType: QgsMapLayerType, targets: Union[Qgis.MapLayerActionTargets, Qgis.MapLayerActionTarget] = Qgis.MapLayerActionTarget.AllActions, icon: QIcon = QIcon(), flags: Union[Qgis.MapLayerActionFlags, Qgis.MapLayerActionFlag] = Qgis.MapLayerActionFlags()) Creates a map layer action which can run on a specific type of layer

canRunUsingLayer(self, layer: QgsMapLayer) bool

Returns True if the action can run using the specified layer.

Deprecated since version use: the version with QgsMapLayerActionContext instead.

canRunUsingLayer(self, layer: QgsMapLayer, context: QgsMapLayerActionContext) -> bool Returns True if the action can run using the specified layer.

Note

Classes which implement this should return False to the deprecated canRunUsingLayer() method which does not accept a QgsMapLayerActionContext argument.

New in version 3.30.

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
