Erasing items in a treemodel

["Juan A. Moreno" <jamf gm gmail com>]

Hello list.

I have some questions about erasing items in a treeview. After read the treemodel documentation, it is not clear for me if erasing a row implies the automatic erasing of child rows. Also I don't know if treemodel clear method erase all rows and childs.

Thanks,
Juan Ángel
