You can create the TreeView::ModelColumn dynamically, and always be
careful to dynamic_cast<> it to the derived type when you read data out.
I do this here, though it's in the middle of some other complicated and
ugly code:
http://git.gnome.org/browse/glom/tree/glom/utility_widgets/adddel/adddel.cc#n559

It's not particularly easy or pretty, I'm afraid.


For some similar code that shows (and edits) a database table, I used a
custom TreeModel. That's not pretty either:
http://git.gnome.org/browse/glom/tree/glom/mode_data/db_adddel/db_adddel.cc
http://git.gnome.org/browse/glom/tree/glom/mode_data/datawidget/treemodel_db.h

Well, that part of the Qt API has a lot less compile-time time safety
anyway.
