Solved How to make signals and slots working in a console application? (Event loop not working)

[robro]

Hello,

I have a console application and my main looks basically like that:

#include "myclass"
#include <QCoreApplication>

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

    MyClass myClass;
    myClass.process();

   return a.exec();

"MyClass" is not derived from Qt but in this class another class is instantiated and this is derived from QObject, has the QObject-Marcro and needs a working signal-slot-machanism.

What is necessary that this works?

Thank you very much!

Nothing in particular, only that MyClass doesn't block the event loop, the typical case is running a while(true)

Thanks,

I do not understand this.
If I would have a mainwindow, where would this loop be then?

Where should I integrate this loop?
Where and how could the event loop pause my code execution and execute the signal and slot things?
Wouldn't I need different threads for that?

@robro You misunderstood what @VRonin wrote: you should NOT have such loops. Just use signals/slots in your app - there are no differences to UI apps.
