[Qt-interest] how to write data into file

[Vincent Cai]

Dear all,

         I try to write some different type of data into a file, but failed.
         From below code, what I hope to get in file is: 01 00 02 00 00 00 03
         But what I exactly get is: 123
         Could anybody tell me how to modify below code?

    QFile TSAFile;
    QString tmp;
    const QChar *data;
    quint8 a = 0x01;
    quint16 b = 0x02;
    quint32 c = 0x03;
    tmp += QString::number(a, 16);
    tmp += QString::number(b, 16);
    tmp += QString::number(c, 16);
    data = tmp.constData();
    while (!data->isNull())
    {
        TSAFile.write((char*)data);
        ++data;
    }
    TSAFile.setFileName("C:\\QtDebug.bin");
    TSAFile.close();

Thanks,
Vincent.
