一种方法（我使用的）：

另一种方法（担心Qt升级导致要重新修改代码，没有使用）：

QFileDialog* f = new QFileDialog();f->setOption(QFileDialog::DontUseNativeDialog, true);QGridLayout *layout = static_cast<QGridLayout*>(f->layout());QList< QPair<QLayoutItem*, QList<int> > > moved_items;f->show();for (int i = 0; i < layout->count(); i++) {int row, column, rowSpan, columnSpan;layout->getItemPosition(i, &row, &column, &rowSpan, &columnSpan);if (row >= 2) {QList<int> list;list << (row + 1) << column << rowSpan << columnSpan;moved_items << qMakePair(layout->takeAt(i), list);i--; // takeAt has shifted the rest items}}for (int i = 0; i < moved_items.count(); i++) {layout->addItem(moved_items[i].first,moved_items[i].second[0],moved_items[i].second[1],moved_items[i].second[2],moved_items[i].second[3]);}QLineEdit *line = new QLineEdit();layout->addWidget(line, 2, 0, 1, 4);
