Заполнение из TableModel происходит только для первого столбца

Всем привет.
При дебаге заметил что в методе data(const QModelIndex &index, int role) аргумент role изменяется, и получается что в switch не проходит проверку.
То есть заполняется первый столбец который попал под аргумент со значением 0 а дальше проверка пролетает.
Подскажите, я где то ошибаюсь в реализации или может ошибку допустил?
Спасибо

Ну так вы определили роли. Вот в data их и используйте теперь. role это столбец.

        Только проблема в том что приходится юзать первые контролы. И все вместе это выглядит убого.
