how to restart the MainWindow?

[d@nyal]

Hi everybody,

You know in main function of a default GUI application, a new object of kind MainWindow be created.

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    // make a new MainWindow object : 
    MainWindow w;
    w.show();
    return a.exec();
}

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    // make a new MainWindow object : 
    MainWindow w;
    w.show();
    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

I am looking for a way to restart the the MainWindow, "controlled inside of MainWindow object".
for a example if I click on a bottun on ui, the window would restart and start from the begining...

Can you help me?

You could have MainWindow on the heap, have the buttons terminating the event loop and then delete and recreate the MainWindow object inside your main function, but I'm not sure why you would want to.

The purpose of this is ?

Thanks !
Would you explain more? (if possible with simple code)

I want to restart it, because there are several processes iin my application that I think they slacken the program.
