gtk_tree

["J.Eusebio Roza" <eusebio roza uah es>]

Hi!

I have a problem in a gtk_tree. I have made several subtrees in a main
tree and i've attached several items in that subtree. After this, i've
removed all items in the subtree and the left [+] simbol (point to show
items) in the subtree desappears. When i attach other item in the same
subtree i can not see it and i can not click into [+] simbol because it
doesn´t exist.


What is my problem??

Thanks! Eusebio
