The LabVIEW NXG editor is extensible. You can add new functionality, such as new document types, menu items, properties, and settings.
The Actor Framework, which adds new menu items that generate Actors and Messages, is one example of an add-on that uses plugins to extend the functionality of LabVIEW NXG. To take full advantage of the extensibility of the editor and produce an add-on on the scale of the Actor Framework, you must use C#. However, you can use VI Editor Plugins to create basic G plugins to extend LabVIEW NXG.
End users can run VI Editor Plugins in LabVIEW NXG without installing any additional packages. To create a VI Editor Plugin, you must select the optional LabVIEW NXG Editor Plugin Authoring Tools package when you install LabVIEW NXG through NI Package Manager.
