set_translate_func

Description:

[ Version ( since = "2.12" ) ]
public void set_translate_func (TranslateFunc func, DestroyNotify? destroy_notify)

Sets the function which is used to translate the contexts user-visible strings, for `--help` output.

If you are using gettext, you only need to set the translation domain, see set_translation_domain.

Parameters:

this	a OptionContext
func	the TranslateFunc, or null
data	user data to pass to `func`, or null
destroy_notify	a function which gets called to free `data`, or null
