Internationalization of widgets

Hi isomorphic,
I'm about to internationalize my application, I almost finished internationalizing all my labels and titles, but is there any why to internationalize widgets of SmartGWT ?
Exemple :for ListGrid I want it ot show the message "No item to show" in the appropriate language and when I right click in the culumn I get the menus of Sort..etc with the appropriate language. is there a way to this issue ?
PS : I can use "setEmptyMessage" for my ListGrid but I hope there is a better solution for all the widgets.
thanks
