Detailed Description

The VolumeControl class provides the base interface class for volume control.

VolumeControl::VolumeControl ( QObject * parent = 0 )

Object constructor.

Parameters:

parent

Parent object.

VolumeControl::~VolumeControl ( )

Destructor.

void VolumeControl::checkVolume ( ) [slot]

Forces the volumeChanged signal to emit.

static VolumeControl* VolumeControl::create ( QObject * parent = 0 ) [static]

Creates output volume control object if implemented, otherwise it creates SoftwareVolume object.

Parameters:

parent

Parent object.

int VolumeControl::left ( )

Returns left channel volume.

int VolumeControl::right ( )

Returns right channel volume.

virtual void VolumeControl::setVolume	(	int	left,
		int	right
	)			`[pure virtual]`

Setups volume level. Subclass should reimplement this fucntion.

Parameters:

	left	Left channel volume level. It should be 0..100
	right	Right channel volume level. It should be 0..100

Implemented in SoftwareVolume.

virtual void VolumeControl::volume	(	int *	left,
		int *	right
	)			`[protected, pure virtual]`

Gets current volume.

Parameters:

	left	Pointer to the left volume level.
	right	Pointer to the right volume level

Implemented in SoftwareVolume.

void VolumeControl::volumeChanged	(	int	left,
		int	right
	)			`[signal]`

Emitted when volume is changed.

Parameters:

	left	Left channel volume level. It should be 0..100
	right	Right channel volume level. It should be 0..100
