<![CDATA[Am I misunderstanding or misusing QByteArray::toHex()?]]>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?

Pass the size as a second parameter.
