Well just for the case ... here is a working example (after really 
reading darco's quote of Thomas Muldowney and looking into gabber):

ConstructParams really did the trick. Why ConstructParams and a Class 
instance is needed is beyond my current spare time. Perhaps someone else 
might be interested in fixing this.

An easy one (list instead of a tree)
http://cvs.berlios.de/cgi-bin/viewcvs.cgi/*checkout*/manuproc/Komponenten/examples/owntreemodel.cc?rev=1.1&content-type=text/plain

expect tree emulation and scrollbars to appear in the HEAD revision soon.

It seems like TreeView is _really_ _fast_ but operating on a TreeStore 
with iterators leads you to performance problems with N>1000.
