    \brief 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 \l {setFrequency()}{frequency} as well as search \l
    {searchForward()}{forwards} and \l {searchBackward()}{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 \c org.qt-project.qt.radiotunercontrol/5.0 as
    defined in QRadioTunerControl_iid.
