4、QT背景音乐设置，动图的播放

1.音乐添加，用到的类：QSound
在pro文件中加入：QT += multimedia

void Widget::on_pushButton_clicked()//音乐播放
{
QSound *music=new QSound("C:\\Users\\23625\\Desktop\\untitled2\\Music\\Gaobai.wav",this);
music->play();
// if(loop)
music->setLoops(400);
ui->pushButton->setEnabled(false);
}


2.gif动画的显示QMovie

QMovie *QiXiHappyMovie = new QMovie("C:\\Users\\23625\\Desktop\\MyGirl\\image\\QiXiHappy.gif");
ui->label->setMovie(QiXiHappyMovie);
QiXiHappyMovie->start();
