Returns a newly allocated list of the widgets, normally labels, for which this widget is the target of a mnemonic (see for example, gtk_label_set_mnemonic_widget()). The widgets in the list are not individually referenced. If you want to iterate through the list and perform actions involving callbacks that might destroy the widgets, you <emphasis>must</emphasis> call <literal>g_list_foreach (result, (GFunc)g_object_ref, NULL)</literal> first, and then unref all the widgets afterwards. mnemonic labels; free this list with g_list_free() when you are done with it.
