If I am using

QLineEdit *le = new QLineEdit();
le->setText("aabbccdd");
 
QByteArray hexData = QByteArray::fromHex(le->text().toAscii());

QLineEdit *le = new QLineEdit();
le->setText("aabbccdd");

QByteArray hexData = QByteArray::fromHex(le->text().toAscii());

To copy to clipboard, switch view to plain text mode 

Is QByteArray going to encode it by the systems endian or is going to respect the order given in the QLineEdit?

qebug() << hexData.toHex();

qebug() << hexData.toHex();

To copy to clipboard, switch view to plain text mode 

Debug appears to keep the byte order given, but if I am to use QByteArray::toInt() and back to hex etc do I need to track endian or will Qt do it for me?

QByteArray operates on bytes, which don't suffer from endianness. fromHex() will process the string from left to right replacing every two characters with a single byte.

You don't have to worry about endianness as long as you don't do any casts or pass data between systems.
