Qbytearray easy question

[arturs]

Hi

I have the following problem:

QByteArray test;
    test[0]= 0xAB;
    test[1]= 0xCD;
    test[2]= 0xEF;
    test[3]= 0x01;
    test[4]= 0x02;
    test[5]= 0x03;
    test[6]= 0x04;
 
qDebug () << test.at(0);

QByteArray test;
    test[0]= 0xAB;
    test[1]= 0xCD;
    test[2]= 0xEF;
    test[3]= 0x01;
    test[4]= 0x02;
    test[5]= 0x03;
    test[6]= 0x04;

qDebug () << test.at(0);

To copy to clipboard, switch view to plain text mode 

test.at(0) gives me QChar but I need to display Hex Value

for at(0) is diplayed « instead of 0xAB

How to display hex value ?
