Can I use your example without the need of changing my code?

What you are saying is something like this:

self.topTitle =
QtGui.QLabel(QtGui.QApplication.translate("dial_Projet2", "Créer les
deux fichiers", None, QtGui.QApplication.UnicodeUTF8))


QtGui.QPushButton(QtGui.QApplication.translate("dial_Projet2", "Créer
les deux fichiers", None, QtGui.QApplication.UnicodeUTF8))

Is that possible?

And what are the parameters? The context (dial_project2) needs to be what?
