main loop

[dusza]

Hi, I want to communicate with server to receive information. I do it in infinite while loop in other thread but I can't use threads so I have to include the thread's code somewhere into MainWindow Class. I've tried below showing main window function but the application doesn't want to show the form. I don't know is there something like main loop in qt because i could not find it in google.

QApplication a(argc, argv);
    MainWindow w;
    w.show();
 
    while(1){}
 
    return a.exec();

QApplication a(argc, argv);
    MainWindow w;
    w.show();

    while(1){}

    return a.exec();
