Hiding Rows in ListStore

[Bellicano Pascal <pascal_bellicano yahoo fr>]

Hello,

Is there a way to hide rows in a GtkListStore ?

Because I have to search my treeview (list) and show only the lines 
containing certain words..

But I want  my list still clickeable to modify items...

Then, I mean if I copy certain rows to another store when my search box 
is not empy (and Items are found) and then user modify a row, It will be 
a problem to find changed rows and reinsert those rows in my orginal list...

The very good trick here would be HIDING row..

Any idea ?
