Thanks for the effort. We are currently migrating the tree/list widgets
to use Haskell data structures as store. As such, I don't know how the
TreeModelFilter module fits in. I think the way the store is implemented
is an orthogonal issue, but certainly your example would have to be
reworked in order to use the new interface. We intend to deprecate the
old interface after the next release.

We'll see if your module fits in. Did you use the apiGen program? It can
do the easy functions automatically and gives you a skeleton for those
functions that it can't do automatically (like the two functions below).

Since the whole module is only available from 2.4 onwards, this comment
should be at the beginning, i.e. in the module descriptions. We then use
ifdefs to comment out all functions if Gtk2Hs is complied against Gtk+
before 2.4.

Thanks for your contribution. We'll put it in before the release (if it
works with the new API). We could put it in with the old API, but that's
probably not of much benefit to people.

Axel.
