"Note that QCoreApplication::exec() must always be called from the
main thread (the thread that executes main()), not from a QThread. In
GUI applications, the main thread is also called the GUI thread
because it's the only thread that is **allowed** to perform
GUI-related operations."

Why is possible access GUI from any thread? This seems not to be
allowed (Phil say "design error") but my application is running
without problems.
