I can understand, you are changing the treeview model, so there is
no way to couple a path/iter to the information if it was expanded or not
(as far as I know).

On the other hand if you have an independent way for defining each line (eg:
the id of th db) you may be able to record the expanded status of each id
*before* changing the model and set it back when setting the new model. 

If your model had one field for the primary key of the db you could just use
that to create such a correspondence.
