empting a tree

[Giovanni Masullo <Giovanni Masullo icn siemens it>]

what is the right way to empty and clear a gtktree?
must i traverse the tree call "free" on each TreeItem/SubTree?
i hope there is a function like "FreeTree" that i can call
on the root tree object and that do the rite work.
can anybody help me?
i look on the tutorial but cant find what i need!
