Hey, Sylvie, what do you really mean?
You are allowed to order by any field in the database just clicking on it in the tree view. If you want to filter by a function field, then you will need to define an order function.
If what you want is to order a tree view by default, then you will need to define a general order to the class or to a specific action as for example it’s done here .
¿Which is your case?

You need to define an order_ function which returns the columns defining the order of the field.
Here is documentation that explains such heature:
