option is to have a more C#-ish model implementation for Gtk#
applications instead of the C-ish mode that we have now.

Anyways, I have not attempted that, but I have a workaround for this
case in the monodoc browser that hooks up to the RowExpanded signal and
tracks the information in a hashtable to be able to populate the tree on
