 //1.添加音乐 qt5里添加音乐需要增加MultiMedia模块，在项目属性里添加即可，并加上这个头文件 #include  使用： QMediaPlayer m_MediaObject; m_MediaObject.setMedia(QUrl("qrc:qrc/sound/enterSound.mp3")); m_MediaObject.play(); 注： enterSound.mp3在qrc里的路径是:/qrc/sound/enterSound.mp3，但是直接使用这个路径播放不出来声音，经过查寻，把路径换成这种qrc:qrc/sound/enterSound.mp3就可以使用，可以两种都试试。 qt5可以获取音乐播放的状态，在OnState槽函数中，可以判断音乐的状态，进而进行你想要的操作。 QObject::connect(&m_MediaObject, SIGNAL(stateChanged(QMediaPlayer::State)), this, SLOT(OnState(QMediaPlayer::State))); void BeatMouse::OnState(QMediaPlayer::State state) { switch (state) { //判断音乐的状态 case QMediaPlayer::StoppedState: //停止 case QMediaPlayer::PlayingState: //播放 break; case QMediaPlayer::PausedState: //暂停 break; default: break; } } //2.添加计时 使用QTimer 设置一个计时器，每间隔1s就刷新一下时间的显示。就能达到计时显示的效果。定义一个QTime 记录时长。 QTimer* m_timeUpdate; QTime m_tTotalTime; //总时长 //3.重玩游戏 重玩游戏就是一个把地鼠归位，时间，分数清零的动作。
