Qbytearray easy question

[Radek]

QByteArray::at() or QByteArray[] is a char - not a QChar. The QChar is a result of a conversion made by qDebug(). If you know the size of the QByteArray, then

const unsigned char *pdata = reinterpret_cast<const unsigned char *>(thearray.constData());

const unsigned char *pdata = reinterpret_cast<const unsigned char *>(thearray.constData());

gives you a pointer to binary data in the QByteArray. The casting is necessary to get rid of signed values (see above, where 0xA0 was output as 0xFFA0, etc.) Now, you can, for example:

qDebug << pdata[i];

qDebug << pdata[i];

or convert to int by simple assigning:

int val = pdata[i];          // no sign extension

int val = pdata[i];          // no sign extension
