How to set up a slot for a console app using QCoreApplication?

[Guerrian]

I see that some people suggest using a slot so that the application can finish when using:

class Runner: public QObject {
    Q_OBJECT
public slots:
    void run();
};

void Runner::run()
{
    // do application stuff here
}

int main(int argc, char *argv[])
{
    QCoreApplication app(argc, argv);
    // how to set up a slot here to "run" the application?
    return app.exec();
}

I can't find a good example of this for a console application.

@Guerrian Have you tried with something like Google? ==> http://treyweaver.blogspot.com/2013/02/qt-console-application-template-tutorial.html

But to reply to your question:

class Runner: public QObject {
    Q_OBJECT
public slots:
    void run();
};

void Runner::run()
{
    // do application stuff here
    ...
    // to quit application
    this->deleteLater();
}

int main(int argc, char *argv[])
{
    QCoreAlippcation app(argc, argv);

    Runner run;

    // to start the runner object
    QTimer::singleShot(0, &run, &Runner::run);

   // to quit application on runner end
    QObject::connect(&run, &QObject::destroyed, &app, &QCoreApplication::quit);
    return app.exec();
}

@KroMignon I get a compile error: undefined reference to `vtable for Runner'

class Runner: public QObject {
    Q_OBJECT
public:
    explicit Runner(QObject *parent = 0);
public slots:
    void run();
};

Runner::Runner(QObject *parent): QObject(parent)
{

}

void Runner::run()
{
    cout << "hi" << endl;
}

@Guerrian
be gracious and gift Runner its own header on cpp files

Hi
The moc tools is only run on .h files
so make sure anything having Q_OBJECT is in a .h

@mrjj said in How to set up a slot for a console app using QCoreApplication?:

The moc tools is only run on .h files

No, moc also runs on .cpp when it finds an include in the form '#include "foo.moc"' (rerunning qmake is needed afaik) but it should be avoided

@Christian-Ehrlicher
Yes i saw that in some of the samples but i consider it a hax :)
