\brief 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
|
|
\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 com.nokia.Qt.QMediaPlaylistControl/1.0 as
|
|
defined in QMediaPlaylistControl_iid.

|
|
|
