Now I understand what was the problem. You get data associated with tree
items and I am trying to get item label. I believe that getting user data
works, but why have twice the same in the tree? I can save as user data
the same as in labels but I don't thing this is the best.

I will use ctree as soon as I compile gtk 1.1. But it still resist all my
afford...:-)
