Hi again,

I did what you told me, it worked, but I have a few questions:


- I have to create a new GtkTreeModelSort everytime the child model is 
modified? or it gets resorted automatically? Example:

   fiter = self.sortedModel.convert_iter_to_child_iter (None, siter)
   miter = self.filter.convert_iter_to_child_iter (fiter)
   self.model.remove (miter)

   self.filter.refilter ()

   self.sortedModel = gtk.TreeModelSort (self.filter)
   self.sortedModel.set_sort_func 
(gui.patientsmodel.PATIENT_OBJECT_COLUMN, 
gui.patientsmodel.patient_sort_func)
   self.sortedModel.set_sort_column_id 
(gui.patientsmodel.PATIENT_OBJECT_COLUMN, gtk.SORT_ASCENDING)
 
   tv.set_model (self.sortedModel)

- About efficiency, everytime I set's the sortedModel to the GtkTreeView 
it takes a few seconds (like 2 secs) to display it. It takes about the 
same with both ways, recreating the sortedModel again and ... well... 
not recreating it (but I don't know if I can do this). There's about 
2.000 rows in the model, is this normal? Suggestions?


thanks, Matias.
