QMediaPlayer how not to play in the background?

Question

Qt

I do something like this

rmusiclist = new QMediaPlaylist();
    rmusiclist->addMedia(QUrl("qrc:/Music/somemusic.mp3"));
    rmusiclist->setPlaybackMode(QMediaPlaylist::Loop);
    rmusic = new QMediaPlayer();
    rmusic->setPlaylist(rmusiclist);
    rmusic->setVolume(80);
    rmusic->play();

I'm launching. Everything works, music plays. How to do what would not play in the background?

Answer 1

What is the question? How to catch the application going into the background, loss of focus?
