      Description

      _stringListModel = new QStringListModel(parent);
      _sortFilterProxyModel->setDynamicSortFilter(true);
      _sortFilterProxyModel->setSortRole(Qt::DisplayRole);
      _sortFilterProxyModel->setSourceModel(_stringListModel);
      
      ui->tableView->setModel(_sortFilterProxyModel);
      _stringListModel->setStringList({"34", "5", "2", "65", "100", "32", "37", "23", "35", "108", "245", "210"});
      

      There is no automatic sorting.

      If you continue to invoke the command:

      _sortFilterProxyModel->sort(0);
      

      The further sorting is performed.

      Looking through the code I realized that it is because the command sets (proxy_sort_column):

      void QSortFilterProxyModel::sort(int column, Qt::SortOrder order)
      { 
        Q_D(QSortFilterProxyModel);
        if (d->dynamic_sortfilter && d->proxy_sort_column == column && d->sort_order == order)
          return;
        d->sort_order = order;
        d->proxy_sort_column = column;
        d->update_source_sort_column();
        d->sort();
      }
      

      And also (proxy_sort_column) is set when:

      _q_sourceColumnsInserted, _q_sourceColumnsRemoved

      which in (QStringListModel) are missing.

      Is this a normal situation or a bug?
