int main(int argc, char *argv[])

{

    QApplication a(argc, argv);

    QSplashScreen spl;

    spl.setPixmap(QPixmap("./1.gif"));

    spl.show();

    a.processEvents();

    QDateTime n=QDateTime::currentDateTime();

    QDateTime now;

    do{

        now=QDateTime::currentDateTime();

    } while (n.secsTo(now)<=5);//6为需要延时的秒数

    Dialog w;

    w.show();

    spl.finish(&w);

    return a.exec();

}
