bool QMediaServerSession::isMuted () const [pure virtual]
Return the current mute state of the session.
quint32 QMediaServerSession::length () [pure virtual]
Return the length of the content.
void QMediaServerSession::lengthChanged ( quint32 ms ) [signal]
Inform listeners the length of the content is changed to ms milliseconds long.
void QMediaServerSession::pause () [pure virtual]

QtopiaMedia::State QMediaServerSession::playerState () const [pure virtual]
Return the current state of the session.
void QMediaServerSession::playerStateChanged ( QtopiaMedia::State state ) [signal]
Inform listeners that the current state of the session has changed. The new state is indicated by state.
void QMediaServerSession::positionChanged ( quint32 ms ) [signal]
Inform listeners that the current play position in the content has changed to ms, from the beginning.
QString QMediaServerSession::reportData () const [pure virtual]
This is a general reporting mechanisim, the QString from this function will be placed in the Value Space for inspection.
void QMediaServerSession::resume () [pure virtual]

void QMediaServerSession::seek ( quint32 ms ) [pure virtual]
Seek the content to ms milliseconds from the beginning. If the session is not seekable it may ignore this function.
void QMediaServerSession::setDomain ( QString const & domain ) [pure virtual]
Sets the audio domain in which this session is active to domain.
See also domain().
void QMediaServerSession::setMuted ( bool mute ) [pure virtual]

See also isMuted().
void QMediaServerSession::setVolume ( int volume ) [pure virtual]
