gtk:about-dialog-translator-credits (object)

object -- a gtk:about-dialog widget
credits -- a string for the credits to the translators

The accessor for the translator-credits slot of the gtk:about-dialog class gets or sets the translator credits string which is displayed in the credits page.

The intended use for this string is to display the translator of the language which is currently used in the user interface. Using GNU gettext, a simple way to achieve that is to mark the string for translation:

gtk_about_dialog_set_translator_credits (about, _("translator-credits"));  

It is a good idea to use the customary "translator-credits" msgid for this purpose, since translators will already know the purpose of that msgid, and since the gtk:about-dialog widget will detect if the translator-credits property is untranslated and hide the tab.
