Raw data conversion using (?) QByteArray

[michelson]

Hello,
is there any built-in-qt mechanism to perform such convesion(s)?

char raw_bytes[4] = {0x00, 0x00, 0xff, 0xff};
QByteArray byte_array = QByteArray::fromRawData(raw_bytes, 4);
byte_array.toInt(); // <- i wanted it to return 65535 but result is 0

You're almost there:

char raw_bytes[4] = {0x00, 0x00, 0xff, 0xff};
QByteArray byte_array = QByteArray::fromRawData(raw_bytes, 4);
QDataStream in(&byte_array, QIODevice::ReadOnly);

quint16 value;
in >> value; // First 2 bytes, gives 0
in >> value; // Second 2 bytes, 65535

Hi!

char raw_bytes[4] = {0x00, 0x00, 0xff, 0xff};
QByteArray byte_array = QByteArray::fromRawData(raw_bytes, 4);
QDataStream stream(byte_array);
int result;
stream >> result;
qDebug() << result; // 65535

Cheers!

Alright, I think this one can do. Thank you both!
