I need to execute my QT program from Window command line interface. What changes i need to do in Main() and how i can call this through command line??
My program main function is..

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();

    return a.exec();
}

Any suggestion and help would be appreciated.
Thanks
