Solved QByteArray : Converts data in bytes.
-
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');
