Detailed Description

Storage and management of actions associated with a layer.

Actions can trigger custom code or applications to be executed based on attributes of a given feature.

Constructor & Destructor Documentation

◆ QgsActionManager()

QgsActionManager::QgsActionManager ( QgsVectorLayer * layer )

inline

Constructor.

Definition at line 57 of file qgsactionmanager.h.

Member Function Documentation

◆ action()

QgsAction QgsActionManager::action ( QUuid id )

Gets an action by its id.

Since: QGIS 3.0

Definition at line 271 of file qgsactionmanager.cpp.

◆ actions()

QList< QgsAction > QgsActionManager::actions ( const QString & actionScope = QString() ) const

Returns a list of actions that are available in the given action scope.

If no action scope is provided, all actions will be returned.

Since: QGIS 3.0

Definition at line 172 of file qgsactionmanager.cpp.

◆ addAction() [1/3]

void QgsActionManager::addAction ( const QgsAction & action )

Add a new action to this list.

Definition at line 60 of file qgsactionmanager.cpp.

◆ addAction() [2/3]

QUuid QgsActionManager::addAction	(	QgsAction::ActionType	type,
		const QString &	name,
		const QString &	command,
		bool	capture = `false`
	)

Add an action with the given name and action details.

Will happily have duplicate names and actions. If capture is true, when running the action using doAction(), any stdout from the process will be captured and displayed in a dialog box.

Definition at line 46 of file qgsactionmanager.cpp.

◆ addAction() [3/3]

QUuid QgsActionManager::addAction	(	QgsAction::ActionType	type,
		const QString &	name,
		const QString &	command,
		const QString &	icon,
		bool	capture = `false`
	)

Add an action with the given name and action details.

Will happily have duplicate names and actions. If capture is true, when running the action using doAction(), any stdout from the process will be captured and displayed in a dialog box.

Definition at line 53 of file qgsactionmanager.cpp.

◆ clearActions()

void QgsActionManager::clearActions ( )

Removes all actions.

Definition at line 160 of file qgsactionmanager.cpp.

◆ defaultAction()

QgsAction QgsActionManager::defaultAction ( const QString & actionScope )

Each scope can have a default action.

This will be saved in the project file.

Since: QGIS 3.0

Definition at line 287 of file qgsactionmanager.cpp.

◆ doAction() [1/2]

void QgsActionManager::doAction	(	QUuid	actionId,
		const QgsFeature &	feature,
		const QgsExpressionContext &	context
	)

Does the action using the expression engine to replace any embedded expressions in the action definition.

Parameters

actionId	action id
feature	feature to run action for
context	expression context to evaluate expressions under

Definition at line 139 of file qgsactionmanager.cpp.

◆ doAction() [2/2]

void QgsActionManager::doAction	(	QUuid	actionId,
		const QgsFeature &	feature,
		int	defaultValueIndex = `0`,
		const QgsExpressionContextScope &	scope = `QgsExpressionContextScope()`
	)

Does the given action.

Parameters

actionId	action id
feature	feature to run action for
defaultValueIndex	index of the field to be used if the action has a $currfield placeholder.
scope	expression context scope to add during expression evaluation

Note: available in Python bindings as doActionFeature

Returns the layer.

Definition at line 124 of file qgsactionmanager.h.

◆ readXml()

bool QgsActionManager::readXml ( const QDomNode & layer_node )

Reads the actions in in XML format.

Definition at line 244 of file qgsactionmanager.cpp.

◆ removeAction()
