OptionContext.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 [glib.option_context.OptionContext.new_]), the summary (see [glib.option_context.OptionContext.setSummary]) and the description (see [glib.option_context.OptionContext.setDescription]).

If you are using gettext(), you only need to set the translation domain, see [glib.option_context.OptionContext.setTranslationDomain].
