How to set Qt::Vertical headerData of QSqlQueryModel increasing numbers when doing pagination

[umen242]

im doing simple pagination with QSqlQueryModel select from limit query's
every thing is working fine . but. now i like to reflect the Vertical headerData of the QTableView .
im implementing the headerData , beacose it is const function i can't do any calculation inside it . so i have problem to calculate the right numbers in the Vertical headers. for example is im getting the rows from 20 to 30 .
i like the Vertical header show the numbers 20 to 30 . and so on ...
this is how i implement the headerData

@QVariant PlayListSqlModel::headerData(int section, Qt::Orientation orientation, int role) const
{

if(orientation == Qt::Vertical && role == Qt::DisplayRole)
{

    return section;
}
if (role == Qt::DisplayRole)
{

    if (orientation == Qt::Horizontal) {
        switch (section)
        {
        case 0:
            return QString("name");
        case 1:
            return QString("From");
        case 2:
            return QString("Created Time");
        case 3:
            return QString("last name");
        case 4:

        }
    }
}
return QVariant();

"case 4" does not have a statement. You must add a regular statement/return statement or just break.
