If a QMediaService contains an internal playlist it will implement QMediaPlaylistControl. This control provides access to the contents of the \l {playlistProvider()}{playlist}, as well as the \l {currentIndex()}{position} of the current media, and a means of navigating to the \l {next()}{next} and \l {previous()}{previous} media. The functionality provided by the control is exposed to application code through the QMediaPlaylist class. The interface name of QMediaPlaylistControl is \c org.qt-project.qt.mediaplaylistcontrol/5.0 as defined in QMediaPlaylistControl_iid. \sa QMediaService::requestControl(), QMediaPlayer */ /*! \macro QMediaPlaylistControl_iid \c org.qt-project.qt.mediaplaylistcontrol/5.0 Defines the interface name of the QMediaPlaylistControl class. \relates QMediaPlaylistControl */ /*!
