Qt-字符串接接的方法

我用的功能：

1  //strTempDataFloader.sprintf ("/%04d/%02d/%02d/%s_filelist_%04d%02d%02d.txt",
2         //                             dt1.date().year(), dt1.date().month(), dt1.date().day(),
3         //                             strType.data(), dt1.date().year(), dt1.date().month(), dt1.date().day());
4         strTempDataFloader =    QString ("/%1/%2/%3/%4_filelist_%1%2%3.txt").arg (dt1.toString ("yyyy"), dt1.toString ("MM"), dt1.toString ("dd"), strType);
1  //QString strTemp = QString ("%02").arg (a, 2, 10, QChar ('0'));
2     ////  QDateTime dt = QDateTime::fromString (QString ("%1-%2-%3").arg (iYear).arg (iMonth).arg (ui.calendarWidget->selectedDate().toString (tr ("dd "))), "yyyy-MM-dd");
3     //ui.timeLabel->setText (QString ("%1-%2-%3").arg (iYear).arg (iMonth, 2, 10, QChar ('0')).arg (ui.calendarWidget->selectedDate().toString (tr ("dd ")), 2));
4     ////  QMessageBox::information (this, "test", FileOpeartion::GetTheTextContent (QString::number (iYear, 10)));
