Catch this event to terminate your add-on when the application is closed.

Catch this event when you want to check what company was selected, especially in cases there your add-on is designed for a specific company.

Catch this event to make sure the language of the add-on corresponds to the language of the application. After the user interface language is changed, actions made on the menu are deleted because the menu is reloaded from the resource file. We recommend refreshing menu actions every time this event occurs.
