Method Documentation

__init__	(	self,
		Phonon.Category	category,
		QObject	parent=0
	)

Creates a new AudioOutput that defines output to a physical device.

Parameters:

category

The category can be used by mixer applications to group volume controls of applications into categories. That makes it easier for the user to identify the programs. The category is also used for the default output device that is configured centrally. As an example: often users want to have the audio signal of a VoIP application go to their USB headset while all other sounds should go to the internal soundcard.

Parameters:

parent

QObject parent

__init__	(	self,
		QObject	parent=0
	)

Phonon.Category category ( self )

Returns the category of this output.

See also:: AudioOutput(Phonon.Category, QObject *)

bool isMuted ( self )

mutedChanged	(	self,
		bool	a0
	)

This signal is emitted when the muted property has changed. As this property can change by IPC (DBus) calls a UI element showing the muted property should listen to this signal.

Signal syntax:: QObject.connect(source, SIGNAL("mutedChanged(bool)"), target_slot)

QString name ( self )

Phonon.AudioOutputDevice outputDevice ( self )

outputDeviceChanged	(	self,
		Phonon.AudioOutputDevice	newAudioOutputDevice
	)

This signal is emitted when the (hardware) device for the output has changed.

The change can happen either through setOutputDevice or if the global configuration for the used category has changed.

See also:: outputDevice

Signal syntax:: QObject.connect(source, SIGNAL("outputDeviceChanged(const AudioOutputDevice&)"), target_slot)

setMuted	(	self,
		bool	mute
	)

setName	(	self,
		QString	newName
	)

bool setOutputDevice	(	self,
		Phonon.AudioOutputDevice	newAudioOutputDevice
	)

setVolume	(	self,
		float	newVolume
	)

setVolumeDecibel	(	self,
		float	newVolumeDecibel
	)

float volume ( self )

volumeChanged	(	self,
		float	newVolume
	)

This signal is emitted whenever the volume has changed. As the volume can change without a call to setVolume (calls over dbus) this is important to keep a widget showing the current volume up to date.

Signal syntax:: QObject.connect(source, SIGNAL("volumeChanged(qreal)"), target_slot)

float volumeDecibel ( self )
