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
must call `g_list_foreach (result,
(GFunc)g_object_ref, NULL)` first, and then unref all the
widgets afterwards.
