How to save Qstring from QTableView

[wodzu-96]

Ok I check this and selectionL is empty but i don't know why and what should I do. Sorry but I am inexperianced. I create table in this function:

model = new QSqlTableModel(this);
        model ->setTable(ntabeli);
        model ->select();
    ui->tableView->setModel(model);

model = new QSqlTableModel(this);
        model ->setTable(ntabeli);
        model ->select();
    ui->tableView->setModel(model);

To copy to clipboard, switch view to plain text mode
