Constructor & Destructor Documentation

◆ QgsMapLayerAction() [1/3]

QgsMapLayerAction::QgsMapLayerAction ( const QString &  name,
QObject *  parent,
Targets  targets = AllActions,
const QIcon &  icon = QIcon(),
QgsMapLayerAction::Flags  flags = QgsMapLayerAction::Flags() 
)

Action behavior flags.

Since
QGIS 3.0 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.

Definition at line 20 of file qgsmaplayeractionregistry.cpp.

◆ QgsMapLayerAction() [2/3]

QgsMapLayerAction::QgsMapLayerAction ( const QString &  name,
QObject *  parent,
QgsMapLayer layer,
Targets  targets = AllActions,
const QIcon &  icon = QIcon(),
QgsMapLayerAction::Flags  flags = QgsMapLayerAction::Flags() 
)

Creates a map layer action which can run only on a specific layer.

Definition at line 27 of file qgsmaplayeractionregistry.cpp.

◆ QgsMapLayerAction() [3/3]

QgsMapLayerAction::QgsMapLayerAction ( const QString &  name,
QObject *  parent,
QgsMapLayerType  layerType,
Targets  targets = AllActions,
const QIcon &  icon = QIcon(),
QgsMapLayerAction::Flags  flags = QgsMapLayerAction::Flags() 
)

Creates a map layer action which can run on a specific type of layer.
