Hi,
I'm using QSqlTableModel to interact with sqlite database. I have connected QSortFilterProxyModel to filter results in QTableView.
Now I'm wondering how can I add two and more virtual columns that I don't have in model, but I want to have in view.
I have read the topic: http://www.qtcentre.org/threads/8070...l-quot-columns and http://www.qtcentre.org/threads/1565...virtual-column but it adds only one of column.
Which and how should I reimplement QSortFilterProxyModel to add more than one column? More precise, how is realized passing information about position in QTableView to model?

Thanks in advance for every hint.
