A curiosity about QApplication
Message 1 in thread
Reading the QT offical guide (http://doc.trolltech.com/3.3/threads.html) we
can found the following statement:
"Qt does not support creating QApplication and running the event loop (with
QApplication::exec()) in a secondary thread. You must create the
QApplication object and call QApplication::exec() from the main() function
in your program."
It's a matter of curiosity... but why shouldn't QApplication::exec work if
called in a secondary thread? Is the main thread "special" somehow? As far
as I know Linux mangages all threads in the the same way, so why should this
be a problem?

I don't think this limitation is related to Linux - rather Mac OS if I recall
correctly.
