qt-设置启动界面

#include "musicwidget.h"

#include <QApplication>

#include <QDateTime>

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

{

    QApplication a(argc, argv);

    QPixmap pixmap(":/resources/default_album.jpg");    //启动界面图片

    QSplashScreen screen(pixmap);

    screen.show();

    screen.showMessage("LOVE", Qt::AlignCenter, Qt::red);   

    a.processEvents();                       //防止界面卡死

    screen.showMessage("LOVE");

    QDateTime n=QDateTime::currentDateTime();

    QDateTime now;

    do{

         now=QDateTime::currentDateTime();

    } while (n.secsTo(now)<=5);

    MusicWidget w;

    w.show();

    screen.finish(&w);

    return a.exec();
