setTranslateFunc

Sets the function which is used to translate the contexts user-visible strings, for --help output. If @func is null, strings are not translated.

Note that option groups have their own translation functions, this function only affects the @parameter_string (see g_option_context_new()), the summary (see g_option_context_set_summary()) and the description (see g_option_context_set_description()).

If you are using gettext(), you only need to set the translation domain, see g_option_context_set_translation_domain().
