i am not sure what happend.
my program need sort part of lines in tableview, and i use function : moveSection. but it is not work .....
i found that index is not change after moveSection .
my code :

    for(int ii = startIdx; ii <= endIdx; ii++)
    {
        for(int j = startIdx; j <=  (endIdx - 1) ;j++)
        {
            if(model->item(j, m_s)->data(Qt::UserRole + 2).toDouble() > model->item(j + 1, m_s)->data(Qt::UserRole + 2).toDouble())
            {
                ui->optionsView->verticalHeader()->moveSection(j, j + 1);
                qApp->processEvents();
            }
}

how to sort part of lines in tableview ?

Hi,

If you want to do sorting on your views, you should rather consider QSortFilterProxyModel or implement your own QAbstractProxyModel.
