Update a GtkTreeView

[Emmanuel Di Pretoro <edipreto skynet be>]

Hi, 

I've created a GtkTreeView with a GtkListStore to show a list of
authors. So, when I update my list of authors, how can I easily update
the GtkTreeView. 

My list is sorted by name of authors, so, must I clear my GtkListStore,
and recreate it ? 

Is it a better way ?
