How to convert string like 0x0102 0x304f to QByteArray?

Question

Qt

Hello.
We have a QString like "0x0102 0x304f" and so on, it needs to be converted to a QByteArray. So that it
contains qarr[0] = 0x01
qarr[0] = 0x02
qarr[0] = 0x30
qarr[0] = 0x4f

Answer 1

QString str = "0x0102 0x304f";
str.remove("0x");
str.remove(" ");
QByteArray arr = str.toLatin1();
QByteArray qarr = QByteArray::fromHex(arr);

Answer 2

What do you need a dock for?

QString str;
QByteArray array;
array.append(str);
