        You don't need an event loop, so don't call exec().

        @
        // Replace this...
        return a.exec();

        // ...with this:
        return 0;
        @

        If you call exec(), you need to quit your program by triggering QCoreApplication::exit() or QCoreApplication::quit()

            I don't think QCoreApplication::notify(), which is used to deliver events, is what you want.

            There's a QCoreApplication::aboutToQuit() signal that indicates that the main event loop is about to terminate, which works pretty well for applications that end main() with "return app.exec();" Minus an event loop, much of Qt won't be of use.

            Perhaps a function that uses printf() and is registered with atexit() will work.

                  @void terminateTest()
                  {
                  qDebug()<<"program is over"<<endl;
                  rootThreadpro.aboutToQuit();
                  }

                  int main(int argc, char *argv[])
                  {
                  QCoreApplication a(argc, argv);

                  qDebug()<<"Root\n";
                  atexit(terminateTest);
                  rootThreadpro.StartServer(); 
                  return a.exec&#40;&#41;;

                    Just launch your other program before return 0;

                    I don't recommend closing a console application by clicking the 'X' or Ctrl-C. If your program terminates like this, it won't be able to clean up. Sometimes, this can corrupt your data files.

                      It looks like atexit() won't work without some additional handling.

                      bq. Functions registered using atexit() (and on_exit(3)) are not called if a process terminates abnormally because of the delivery of a signal.

                        Like I said, do not use Ctrl-C, and do not close your console by clicking the 'X'. These are dangerous ways to stop a program.

                        Why don't you quit your program properly?

                        Or, if you really want to close by clicking the 'X', create a QWidget-based GUI. Then, when you click the 'X', you will get a QCloseEvent.
