Am I misunderstanding or misusing QByteArray::toHex()?

[In Fo]

I have a

char[32] data;

populated with some data and its bytes increment from 0x00 to 0xff one after another over the course of the algorithm. When I call

auto hex = QByteArray(data).toHex();

every time hex contains an empty array regardless of the increments of data bytes.

What's the trick?

If first element in data is 0x00 then QByteArray(data) will be empty (it assumes a null terminated string). Pass the size as a second parameter.
