c++ - QFileInfo 所有者和组为空

Question

这是我的位置:

void MainWindow::writeOnFile(const QString &path)
{
    // Get info files :
    QFileInfo fileInfo(path);
    QString name = fileInfo.fileName();
    QString lastModif = fileInfo.lastModified().toString();
    QString owner = fileInfo.owner();
    QString group = fileInfo.group();
    QString lastRead = fileInfo.lastRead().toString();
    QString created = fileInfo.created().toString();


    // Write on Logs :
    QString filename = "C:\\Users\\Sherlock\\Desktop\\logs.txt";
    QFile file ( filename );
    if ( file.open(QIODevice::WriteOnly | QIODevice::Append | QIODevice::Text) )
    {
        QTextStream stream( &file );
        stream << "The file " << name
               << " was first created on " << created
               << ", was last read on " << lastRead
               << " and was last modified on " << lastModif
               << ". The owner is " << owner
               << ". The group is " << group
               << endl;
    }
}

这是我的输出:

The file younes.txt was first created on lun. août 17 19:40:34 2015, was last read on lun. août 17 19:40:34 2015 and was last modified on mar. août 18 00:21:51 2015. The owner is . The group is

如您所见，未显示所有者和组。

我做错了什么吗？

On Windows [...] an empty string is returned.

因此，据记载 group() 以这种方式工作。
