QgsActionMenu() [1/2]

QgsActionMenu::QgsActionMenu ( QgsVectorLayer *  layer, const QgsFeature &  feature, const QString &  actionScope, QWidget *  parent = nullptr  )

explicit

Constructs a new QgsActionMenu.

Parameters

layer	The layer that this action will be run upon.

explicit

Constructs a new QgsActionMenu.

Parameters

layer	The layer that this action will be run upon.
fid	The feature id of the feature for which this action will be run.
parent	The usual QWidget parent.

isEmpty()

bool QgsActionMenu::isEmpty

(

)

const

Returns true if the menu has no valid actions.

menuActions()

QList< QgsAction > QgsActionMenu::menuActions

(

)

Returns menu actions.

Since

signal

setActionContextGenerator()

void QgsActionMenu::setActionContextGenerator

(

QgsMapLayerActionContextGenerator *

generator

)

Sets a QgsMapLayerActionContextGenerator to create action contexts for the menu.

The generator object must exist for the lifetime of the menu.

Since

QGIS 3.30

setExpressionContextScope()

void QgsActionMenu::setExpressionContextScope

(

const QgsExpressionContextScope &

scope

)

Sets an expression context scope used to resolve underlying actions.

Definition at line 221 of file qgsactionmenu.cpp.

setFeature()

void QgsActionMenu::setFeature

(

const QgsFeature &

feature

)

Change the feature on which actions are performed.

Parameters

feature

A feature. Will not take ownership. It's the callers responsibility to keep the feature as long as the menu is displayed and the action is running.

Definition at line 73 of file qgsactionmenu.cpp.

setMode()

void QgsActionMenu::setMode

(

QgsAttributeEditorContext::Mode

mode

)

Change the mode of the actions.

Parameters

mode	The mode of the attribute form
