[Gtk-sharp-list] Preventing Dups In a ListStore

I have a ListStore -
panelStore = new Gtk.ListStore (typeof (Whitemice.ZOGI.Entity));
- used to hole a collection of participants. In the UI the user can
search for additional participants in a dialog which then puts the
selected participants into the list; all good. But what is the
simplest / most efficient way to prevent dups in a ListStore? I don't
want to have the same entity added twice, if it is already there I'd
prefer to just ignore the operation.
if (!(panelStore.Contains(entity))) panelStore.AppendValues(entity);
- but, of course, there is no Contains [or equivalent] method in a
ListStore. And the ListStore doesn't seem to care about storing
multiple references to an object.
Do I need to iterate the contents every time I add an object in order to
prevent dups? Or is there some kind of short-cut that I'm missing?
