		const QSet< QString > &	actionScopes = `QSet<QString>()`,
		const QString &	notificationMessage = `QString()`,
		bool	enabledOnlyWhenEditable = `false`
	)

inline

Create a new QgsAction.

Parameters

type	The type of this action
description	A human readable description string
action	The action text. Its interpretation depends on the type
icon	Path to an icon for this action
capture	If this is set to `true`, the output will be captured when an action is run
shortTitle	A short string used to label user interface elements like buttons
actionScopes	A set of scopes in which this action will be available
notificationMessage	A particular message which reception will trigger the action
enabledOnlyWhenEditable	if `true` then action is only enable in editmode
