Detailed Description

The QRadioTunerControl class provides access to the radio tuning functionality of a QMediaService.

If a QMediaService can tune an analog radio device it will implement QRadioTunerControl. This control provides a means to tune a radio device to a specific frequency as well as search forwards and backwards for a signal.

The functionality provided by this control is exposed to application code through the QRadioTuner class.

The interface name of QRadioTunerControl is com.nokia.Qt.QRadioTunerControl/1.0 as defined in QRadioTunerControl_iid.

See also QMediaService::requestControl() and QRadioTuner.
