TreeView question

I try use a TreeView with libglade2 library … it work fine writing
data in this TreeView… but when I don’t know how I drop all rows in
this TreeView… Somebody can tell me something about this?

I was reading information about this in page Ruby-Gnome2 [1] and old
posts in this mail list about this but I didn’t see nothing.

Somebody can help me?

                  Thanks, bye
