c++ - 如何在 Qt 中将 TreeView 保存为 .csv 文件？

Question

我需要将我的 QTreeView(QSortFilterProxyModel 和 QStandardItemModel)的当前 View 保存为 .csv 文件。不幸的是，我不知道从哪里开始......

我想我应该使用 QSortFilterProxyModel，因为我需要保存当前 View ，但我不确定...有什么想法吗？有没有办法知道一行是否是父行？

TreeView 是分层的，有 5 列:

.CSV 输出我需要:

"(0028,2110)",LossyImageCo,CS,2,00
"(00028,3000)",ModalityLUTse,SQ,,
 ,"(0028,3002)",LUTDesciptoi,US,6,4096\0\12
etc...

到目前为止我的代码:

for (int i = 0; i < proxyModel->rowCount(); i++)
    {
        for (int j = 0; j < proxyModel->columnCount(); j++)
        {
            QModelIndex index = proxyModel->index(i, j);
            qDebug() << "Data: " << proxyModel->data(index).toString();
            // How do I know when to start a child row?
        }
    }

我创建了一个包含所有父行的文件。如何获取子行？

QFile file(filePath);
            if (file.open(QFile::WriteOnly))
            {
                QTextStream stream(&file);              
                for (int i = 0; i < proxyModel->rowCount(); i++)
                {
                    QModelIndex index0 = proxyModel->index(i, 0);
                    QModelIndex index1 = proxyModel->index(i, 1);
                    QModelIndex index2 = proxyModel->index(i, 2);
                    QModelIndex index3 = proxyModel->index(i, 3);
                    QModelIndex index4 = proxyModel->index(i, 4);
                    stream << proxyModel->data(index0).toString() << "," <<  proxyModel->data(index1).toString() << "," << proxyModel->data(index2).toString() << "," << proxyModel->data(index3).toString() << "," << proxyModel->data(index4).toString();
                    stream << "\n";                 
                }
                file.close();
            }

输出:

要迭代 QTreeWidget 子项，请使用 QTreeWidget::topLevelItem() 访问顶级项，然后递归地使用 QTreeWidgetItem::child() 迭代低级子项及其子项。

您是否自己加载此 dicom 文件？您还可以查看 gdcmdump 的源代码。修改该代码以输出 csv 而不是其标准输出。那将是直截了当的。
