Looping the audio

Playing our samples in one-shots is neat, but we'd also like to loop them. Looping audio in a QMediaPlayer object requires a slightly different approach. Instead of loading a QMediaContent object directly, we need to first add it to a QMediaPlayList object. We can then tell the playlist to loop.

Back in our set_file() method, we need to make the following changes to our code:

    def set_file(self, url):        self.label.setText(url.fileName())        content = qtmm.QMediaContent(url)        #self.player.setMedia(content)        self.playlist = qtmm.QMediaPlaylist()        self.playlist.addMedia(content)        self.playlist.setCurrentIndex(1)        self.player.setPlaylist(self.playlist)

A playlist can, of course, have multiple files loaded, but, in this case, we only want ...
