Can anyone tell me how to do this konwing that I dispose in my database of all the data in the different langages.

QObject::tr() is the way to go. Wrap every user visible string in it and then run lupdate as usual and do the translation. Then make sure you handle the QEvent::LanguageChange event for each of the classes and retranslate all strings there (Designer generated classes use the retranslateUi() method for this).
