QTableView sorting

[Bojan]

What's the most proper way of sorting a QTableView? QSortFilterProxyModel doesn't seem to work on QTableViews. At least I can't get it to work. For example if I take the sorting treeview example, and just change it so there is a QTableView, it doesn't work:

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    QFile file(":/default.txt");
    file.open(QIODevice::ReadOnly);
    TreeModel model(file.readAll());
    file.close();
 
    QSortFilterProxyModel sortingModel;
    sortingModel.setSourceModel(&model);
 
    QTableView sortedView;
    sortedView.setModel(&sortingModel);
    sortedView.setWindowTitle("Sorted Data");
    sortedView.setSelectionBehavior(QAbstractItemView::SelectRows);
    sortedView.horizontalHeader()->setSortIndicator(0, Qt::AscendingOrder);
    sortedView.horizontalHeader()->setSortIndicatorShown(true);
    sortedView.horizontalHeader()->setClickable(true);
    sortedView.verticalHeader()->setVisible(false);
    sortedView.show();
 
    return app.exec();
}

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    
    QFile file(":/default.txt");
    file.open(QIODevice::ReadOnly);
    TreeModel model(file.readAll());
    file.close();

    QSortFilterProxyModel sortingModel;
    sortingModel.setSourceModel(&model);

    QTableView sortedView;
    sortedView.setModel(&sortingModel);
    sortedView.setWindowTitle("Sorted Data");
    sortedView.setSelectionBehavior(QAbstractItemView::SelectRows);
    sortedView.horizontalHeader()->setSortIndicator(0, Qt::AscendingOrder);
    sortedView.horizontalHeader()->setSortIndicatorShown(true);
    sortedView.horizontalHeader()->setClickable(true);
    sortedView.verticalHeader()->setVisible(false);
    sortedView.show();

    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

I would like to be able to sort the rows based on the column data in the clicked column. Qt 4.1. I don't need sample source code, just description of what to do, what things to connect, etc... Any advice is much appreciated.
