Yes, I know that, but i don't want to duplicate data, and i need to
store all my data on an treestore, it should be easy to create a
filter that let show only the elements with no children, with that a
treemodelfilter works like it has a liststore as model, but it is also
needed the LIST_ONLY flag for the iconview.

I was thinking in create a new class that inherits from a
Gtk::TreeModelFilter, but i can't override the get_flags method
