QMediaObject::QMediaObject ( QObject * parent, QMediaService * service ) [protected]

Constructs a media object which uses the functionality provided by a media service.

The parent is passed to QObject.

This class is meant as a base class for Multimedia objects so this constructor is protected.

This function was introduced in Qt Mobility 1.0.

QMediaObject::~QMediaObject ()

Destroys a media object.

void QMediaObject::addPropertyWatch ( QByteArray const & name ) [protected]

Watch the property name. The property's notify signal will be emitted once every notifyInterval milliseconds.

This function was introduced in Qt Mobility 1.0.

See also notifyInterval.

void QMediaObject::availabilityChanged ( bool available ) [signal]

Signal emitted when the availability state has changed to available

This function was introduced in Qt Mobility 1.0.

QtMultimediaKit::AvailabilityError QMediaObject::availabilityError () const [virtual]

Returns the service availability error state.

This function was introduced in Qt Mobility 1.0.

QStringList QMediaObject::availableExtendedMetaData () const

Returns a list of keys there is extended meta-data available for.

This function was introduced in Qt Mobility 1.0.

QList<QtMultimediaKit::MetaData> QMediaObject::availableMetaData () const

Returns a list of keys there is meta-data available for.

This function was introduced in Qt Mobility 1.0.

bool QMediaObject::bind ( QObject * object ) [virtual]

Bind object to the QMediaObject instance.

This method establishes a relationship between the media object and a helper object. The nature of the relationship depends on both parties. This methods returns true if the helper was successfully bound, false otherwise.

The object passed must implement the QMediaBindableInterface interface.

This function was introduced in Qt Mobility 1.0.

See also QMediaBindableInterface.

QVariant QMediaObject::extendedMetaData ( const QString & key ) const

Returns the value associated with a meta-data key.

The naming and type of extended meta-data is not standardized, so the values and meaning of keys may vary between backends.

This function was introduced in Qt Mobility 1.0.

bool QMediaObject::isAvailable () const [virtual]

Returns true if the service is available for use.

This function was introduced in Qt Mobility 1.0.

bool QMediaObject::isMetaDataAvailable () const

Returns true if there is meta-data associated with this media object, else false.

This function was introduced in Qt Mobility 1.0.

QVariant QMediaObject::metaData ( QtMultimediaKit::MetaData key ) const

Returns the value associated with a meta-data key.

This function was introduced in Qt Mobility 1.0.

void QMediaObject::metaDataAvailableChanged ( bool available ) [signal]

Signals that the available state of a media object's meta-data has changed.

This function was introduced in Qt Mobility 1.0.

void QMediaObject::metaDataChanged () [signal]

Signals that a media object's meta-data has changed.

This function was introduced in Qt Mobility 1.0.

void QMediaObject::notifyIntervalChanged ( int milliseconds ) [signal]

Signal a change in the notify interval period to milliseconds.

This function was introduced in Qt Mobility 1.0.

void QMediaObject::removePropertyWatch ( QByteArray const & name ) [protected]

This function was introduced in Qt Mobility 1.0.

See also notifyInterval.

QMediaService * QMediaObject::service () const [virtual]

Returns the media service that provides the functionality of a multimedia object.

This function was introduced in Qt Mobility 1.0.
