QTextStream::UppercaseDigits

[mightymark]

Hi, I'm trying to get a string containing a hexadecimal number to have the letters in the number in upper case instead of lower case. I use the code below.
tagID and antennaID are both unsigned intergers.

QString outStr;
	QTextStream tagLine(&outStr);
	tagLine.setNumberFlags(QTextStream::UppercaseDigits);
	tagLine << "TagFound:  " << hex  << tagID << " on Antenna: " << antennaID;

QString outStr;
	QTextStream tagLine(&outStr);
	tagLine.setNumberFlags(QTextStream::UppercaseDigits);
	tagLine << "TagFound:  " << hex  << tagID << " on Antenna: " << antennaID;

To copy to clipboard, switch view to plain text mode 

But the resulting string always has lower case letters in the hex number:
"TagFound: 702f2cba on Antenna: 1"

Any idea what i am doing wrong? thanks
