Ok, but as I wrote you, my problem is with
virtual void get_value_vfunc (const iterator& iter, int column,
Glib::ValueBase& value) const
1) Is this only function that get value from model?
2) When is this function called?
3) Which class call this function?
4) Why is this function being called _number_of_row_ times even if only one row
is visible?
thanks
Trigve
