QByteArray : Converts data in bytes.

[Kycho]

Hello everyone.

I'm having trouble converting to Hex.
First is the code.

    /* Error Code */
    int n1 = 1;
    QByteArray val1 = QByteArray("1B33")+QByteArray::number(n1,16); // val1 : 1B331
    qDebug() << QByteArray::fromHex(val1); //result : "\x01\xB3\x31" ( I do not want this value )
    // I want result : "\x1B\x33\x01"

    /*Good work Code*/
    int n2 = 20;
    QByteArray val2 = QByteArray("1B33")+QByteArray::number(n2,16); // val2 : 1B3314
    qDebug() << QByteArray::fromHex(val2); // result : "\x1B\x33\x14"

If the Hex value of 'int n' is a single digit,
I get results that I did not want.
I want to store the data in bytes.
How do I solve this problem?

I thank you in advance for your advice.

The method varies, but the method by Qt only is something like this.

QByteArray val1 = QByteArray("1B33")+QByteArray::number(n1,16).rightJustified(2, '0');
