Member Function Documentation

QCallVolume::QCallVolume ( const QString & service = QString(), QObject * parent = 0, QCommInterface::Mode mode = Client )

Construct a new call volume object for service and attach it to parent. The object will be created in client mode if mode is Client, or server mode otherwise.

If service is empty, this class will use the first available service that supports call volume. If there is more than one service that supports call volume, the caller should enumerate them with QCommServiceManager::supports() and create separate QCallVolume objects for each.

See also QCommServiceManager::supports().

QCallVolume::~QCallVolume ()

Destroy this call volume object.

void QCallVolume::microphoneVolumeChanged ( int volume )   [signal]

This signal is emitted when the microphone volume changes to volume.

void QCallVolume::speakerVolumeChanged ( int volume )   [signal]

This signal is emitted when the speaker volume changes, to volume.
