I started grasping the idea that it was using the TreeModel Interface
but I currently don't understand interfaces all that well. I managed to
get a little bit further thanks to your reply. I'm not getting the rows
but they're empty. I know that items to be added are getting passed to
the AppendValues method but they're aren't showing up. I'm assuming this
has to do with something along the lines of the TreeView.AppendColumn
but the ComboBox widget doesn't have something similiar (at least I
can't find it). Does this have to do with the TreeModel interface?
This is the similar code to what I have minus other junk that's being done.
What am I missing?
typesSelect = new ComboBox(model);
TreeStore typesStore = new TreeStore(typeof(string));
string  types = userAccount.GetTypes();
typesSelect.Model = typesStore;
for(int i = 0; i < types.Length; i++)
TreeIter iter = typesStore.AppendValues(types[i]);
Thanks for all your help. I've been at this for two days off and on and
it's driving me nuts.
