void gtk_about_dialog_set_translator_credits ( GtkAboutDialog* about, const gchar* translator_credits )
Sets the translator credits string which is displayed in the translators tab of the secondary credits dialog.
The intended use for this string is to display the translator of the language which is currently used in the user interface. Using gettext(), a simple way to achieve that is to mark the string for translation:
GtkWidget *about = gtk_about_dialog_new (); gtk_about_dialog_set_translator_credits (GTK_ABOUT_DIALOG (about), _("translator-credits"));
It is a good idea to use the customary msgid “translator-credits” for this
purpose, since translators will already know the purpose of that msgid, and
GtkAboutDialog will detect if “translator-credits” is untranslated
and hide the tab.
