I assume you are trying to map your tree in a GtkTreeStore, and display
the GtkTreeStore using the GtkTreeView. In that case I would recommend
writing your own GtkTreeModel. This way you don't have to do any
bookkeeping between your tree and the tree in TreeStore.

[That would be GtkTreeRowReference. Though if you have a big tree, you
will have a lot of row references around. This both requires memory and
slows down insertion, deletion and reordering operations. I'd still
recommend to write your own GtkTreeModel, as pointed out above ;)]


Good luck,
