How to convert decimal to hexadecimal with Qt programming?

[nancyred]

Hello,
How to convert decimal to hexadecimal with Qt programming? Such as 69 switch to 45, 56 switch to 38 and so on... I try like this:

QString str = QString::number(s.at(i).unicode());
bool ok;
qDebug() << str.toUtf8();

QString str = QString::number(s.at(i).unicode());
bool ok;
qDebug() << str.toUtf8();

To copy to clipboard, switch view to plain text mode 

but failed. I need to convert this string "E8A5" ASCII switch to hexadecimal number or string.

edit: removed old stuff that did not answer question

You can use QString::toInt or QString::toUInt to convert the hex string to a number, and then QString::number to get back to a string.
