MediaSource Class Reference
(Phonon::MediaSource)
[Phonon module]

Qt Backends

Currently, Qt's backends support files in local and remote locations. Support for other sources, such as CD/DVD, are planned for the future.

See also MediaObject.

Member Type Documentation

enum MediaSource::Type

Identifies the type of media described by the MediaSource object.

See also MediaSource::type().

Member Function Documentation

MediaSource::MediaSource ( const QString & fileName )

Creates a MediaSource object for the file specified by fileName. You can also use this constructor with Qt resources

MediaSource::MediaSource ( const QUrl & url )

Creates a MediaSource object for a the URL specified by url.

If the multimedia content you would like to play back is on a remote network location, you should use this constructor; though, it also possible to specify an URL to a local file.

See also QUrl.

MediaSource::MediaSource ( Phonon::DiscType discType, const QString & deviceName = QString() )

Creates a MediaSource object for the type of disc specified by discType in the named device referred to by deviceName.

Note: deviceName is a platform dependent device name. It can be useful to specify this if the computer has more than one CD drive. On KDE, it is recommended to use the Solid hardware discovery framework to retrieve the device name in a portable way.

MediaSource::MediaSource ( QIODevice * ioDevice )

Creates a MediaSource object for the QIODevice specified by ioDevice.

This constructor can be very handy in the combination of QByteArray and QBuffer.

ioDevice is an arbitrary readable QIODevice subclass. If the device is not opened MediaSource will open it as QIODevice::ReadOnly.

Note: Sequential devices can also be used, but MediaObject::isSeekable() will return false as a result.

See also setAutoDelete().

MediaSource::MediaSource ( const MediaSource & other )

Constructs a copy of the other media source.

This constructor is fast thanks to explicit sharing.

MediaSource::~MediaSource ()

Destroys the MediaSource object.

bool MediaSource::autoDelete () const

Returns the setting of the auto-delete option. The default is false.

See also setAutoDelete().

QString MediaSource::deviceName () const

Returns the device name of the MediaSource if type() == Disc; otherwise returns QString().

See also type().

Phonon::DiscType MediaSource::discType () const

Returns the disc type of the MediaSource if type() == Disc; otherwise returns NoDisc.

See also type().

QString MediaSource::fileName () const

Returns the file name of the MediaSource if type() == LocalFile; otherwise, returns QString().

See also type().

void MediaSource::setAutoDelete ( bool enable )

If enable is true, the media source will take ownership of the object passed in the MediaSource's constructor object that was passed in the constructor; otherwise, the programmer is responsible for deletion of this object.

This setting is false by default. If you enable it, you should only access the stream or device as long as you keep the media source object around. As long as you keep the media source wrapping the stream or device, the object will not get deleted.

See also autoDelete().

Type MediaSource::type () const

Returns the type of the MediaSource (depends on the constructor that was used).

See also Type.

QUrl MediaSource::url () const

Returns the URL of the MediaSource if type() == URL or type() == LocalFile; otherwise returns QUrl().

See also type().

MediaSource & MediaSource::operator= ( const MediaSource & other )

Assigns the other media source to this media source and returns a reference to it.

This operation is fast thanks to explicit sharing.

bool MediaSource::operator== ( const MediaSource & other ) const

Returns true if this media source is equal to the other media source; otherwise returns false.
