This is all about calling i18n() at runtime, from within the widget (when the 
value changes), on a KLocalizedString member (-> i.e. it's based on a delayed 
translation mechanism).
How do you do that from within Qt?

I can see it work with tr(), but not with i18n().

PS: Martin: meanwhile Laurent committed the class (which I reviewed) to 
ktextwidgets, you can use that.
