The QMediaPlaylistControl class provides access to the playlist functionality of a QMediaService.
If a QMediaService contains an internal playlist it will implement QMediaPlaylistControl. This control provides access to the contents of the playlist, as well as the position of the current media, and a means of navigating to the next and previous media.
The functionality provided by the control is exposed to application code through the QMediaPlaylist class.
The interface name of QMediaPlaylistControl is com.nokia.Qt.QMediaPlaylistControl/1.0 as defined in QMediaPlaylistControl_iid.
