There isn't really. Basically gtk does not know wheter the ui is translated or
not. E:g. one calls
gtk_label_set_text(label,_("translated text"));
or
gtk_label_set_text(label,"untranslated text");
for gtk it is just text. To change that we would need a lot of new api, like
gtk_label_set_i18n_text(domain,N_("translated text"));
so that gtk+ could catch changes to the locale and update the UI.

No idea if we could do some black magic for UIs that use gtkbuilder. Something
that allows apps to catch the locale change and systematically set all texts again.
