true. But how will I delete the instance ?
does the TreeModel create a ColumnModel (eg a class derived from
Gtk::TreeModel::ColumnRecord) for each row ?
I could then delete my custom class instance in the destructor of my
ColumnModel class...
But this would only work if the operator = is never used.

I didn't manage to compile all gtk and gtkmm stuff on my windows system. So
I cannot change the code... :-\
