Return row number in QAbstractTableModel headerData

Question

I am using QTableView and QAbstractTableModel. Can I get ordered row numbers in vertical header even after filtering and sorting?

Answer 1

Solution is reimplemented headerData in MySortFilterProxyModel:

QVariant MySortFilterProxyModel::headerData(int section, Qt::Orientation orientation, int role) const
{
    if(role == Qt::DisplayRole && orientation == Qt::Vertical)
        return section + 1;
    else
        return sourceModel()->headerData(section, orientation, role);
}

Answer 2

just like this is enough:

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

    return sourceModel()->headerData(section, orientation, role);
}
