Returns the widgets for which this widget is the target of a
mnemonic.
Typically, these widgets will be labels. See, for example,
[method@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.
