hi Girish,

thanks for the reply, but unfortunately i do not have a QKeyEvent
(actually i need this to be able to create one) ...
I found an approach, which i don't really like at all, but it's what
comes closest to what i want (still far away though ...):
QString text = QKeySequence(Qt::Key_XYZ).toString();
text = (text.length() == 1) ? text : QString();
This somehow works for most keys, but it's of course not guaranteed at
all to work, and it's obviously pretty unclean, since
QKeySequence::toString() returns (int this case) the actual label of a
key as you would see it on your keyboard, like "CapsLock", "Shift",
"Esc", ...

I'm still thankful for everyone who can give me another hint on this!

Sincerely
Julian
