Thank you both for your reply.

I'm working on python, and I can't find functions to add the sortable 
functions to an instance of a GtkTreeModel.

Let's say I have a method that receives a GtkListStore that is sortable:


/* This funcion calls set_model */

def database_changed_cb (self, ccontroller, db, patients):
       self.db = db
       self.patients = patients
       if patients:
           model = gui.patientsmodel.PatientsModel (patients)
           model.set_sortable (True) /* Adds the sort_funcs */
           self.set_model (model)
       else:
           self.set_model (None)

/* This one receives the model and update the GUI */
def set_model (self, model):
       if model:
           self.filter = model.filter_new ()
           self.filter.set_visible_func (self.patient_filter_callback)
           self.patientsBox.tree_view.set_model (self.filter)
           self.unblock_signals ()
           self.patient_selected_callback ()
           self.patientsBox.set_sensitive (True)
       else:
           self.filter = None
           self.patientsBox.tree_view.set_model (None)
           self.patientsBox.set_sensitive (False)
           self.patient_selected_callback ()
           self.block_signals ()


I append these functions to make clear what i'm trying to do. hope this 
help you to help me :P, thanks.
