QTableView修改默认排序方式为降序

我是StackOverflow的搬运工。

参考

Default sort order in QTableView when used with QSortFilterProxyModel

代码

QVariant MyModel::headerData(int section, 
                             Qt::Orientation orientation, 
                             int role) const 
{
    if (role == Qt::InitialSortOrderRole) {
        // use section, orientation, ...
        return QVariant::fromValue(Qt::DescendingOrder); // or maybe Ascending
    }
}
