    Sort display image does not match the sort order.
    code:

    QSqlRelationalTableModel *model = new QSqlRelationalTableModel();
    model->setTable("records");
    ui->tableView->setSortingEnabled(true);
    connect(ui->tableView->horizontalHeader(), 
                &QHeaderView::sortIndicatorChanged,
                this, &MainWindow::on_sortChanged);
    ui->tableView->setModel(model);
    model->select();
    

    slot:

    void MainWindow::on_sortChanged(int index, Qt::SortOrder order)
    {
        qDebug() << index << order 
              << ui->tableView->horizontalHeader()->sortIndicatorOrder();
    }
    

    when i click to header, i see:
    screenshot
    but qDebug print:
    0 Qt::SortOrder(DescendingOrder) Qt::SortOrder(DescendingOrder)
    I tried Qt 5.7.0 and Qt 5.6.2
    It's a QT bug or I doing something wrong?

      Hi and welcome to devnet,

      Are you running a Gnome desktop environment ?

          Can you check with your distribution provided Qt ?

          Also, can you try with one of KDE's application like KMail or any other that uses a QTableView ?

                Then it looks rather like a KDE Theme issue. You should check with them.

                  I think it is a "feature" in Qt style code:

                  alt text

                  Some UI developers thinks, that "^" is ascending sort indicator, other thinks it is a descending sort indicator.
                  Qt platfom-dependend styles (QWindowsVistaStyle, QMacStyle, QGtkStyle, etc..) will draw indicator using current OS & theme settings, platform-independend styles (QFusionStyle, QWindowsStyle) will draw it as hardcoded in Q***Style.cpp
