1、QString::arg()
用字符串变量参数依次替代字符串中最小数值
QString i = "iTest"; // current file's number
QString total = "totalTest"; // number of files to process
QString fileName = "fileNameTest"; // current file's name
QString status = QString("Processing file %1 of %2: %3").arg(i).arg(total).arg(fileName);
qDebug() << status ;
输出结果为："Processing file iTest of totalTest: fileNameTest"
