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

It looks like a Qt bug:

bool QTextStreamPrivate::putNumber(qulonglong number, bool negative)
{
    QString tmp;
    if (negative)
        tmp = QLatin1Char('-');
    else if (numberFlags & QTextStream::ForceSign)
        tmp = QLatin1Char('+');
 
    if (numberFlags & QTextStream::ShowBase) {
        switch (integerBase) {
        case 2: tmp += QLatin1String("0b"); break;
        case 8: tmp += QLatin1String("0"); break;
        case 16: tmp += QLatin1String("0x"); break;
        default: break;
        }
    }
 
    tmp += QString::number(number, integerBase ? integerBase : 10);
    if (numberFlags & QTextStream::UppercaseBase)                   // <--- this is wrong
        tmp = tmp.toUpper(); // ### in-place instead
 
    return putString(tmp);
}

bool QTextStreamPrivate::putNumber(qulonglong number, bool negative)
{
    QString tmp;
    if (negative)
        tmp = QLatin1Char('-');
    else if (numberFlags & QTextStream::ForceSign)
        tmp = QLatin1Char('+');

    if (numberFlags & QTextStream::ShowBase) {
        switch (integerBase) {
        case 2: tmp += QLatin1String("0b"); break;
        case 8: tmp += QLatin1String("0"); break;
        case 16: tmp += QLatin1String("0x"); break;
        default: break;
        }
    }

    tmp += QString::number(number, integerBase ? integerBase : 10);
    if (numberFlags & QTextStream::UppercaseBase)                   // <--- this is wrong
        tmp = tmp.toUpper(); // ### in-place instead

    return putString(tmp);
}
