how to export tree branches

["Calin Vatavu" <cvatavu bumerang ro>]

Hi 

Back in gtk-1.2 there was a gtk_ctree_export_to_gnode function if one wants 
to copy/remove a branch from one ctree and insert it in another/the same  
ctree. 

Does gtk-2.0's GtkTreeModel have something similar?
I've found the gtk_tree_model_foreach function which allows me to call a 
function to ALL nodes, not the ones ancestors of one particular node. 

I think I shouldn't be allowed to use the *_helper function, don't I ?
