55 \brief The QRadioTunerControl class provides access to the radio tuning
56 functionality of a QMediaService.
57
58 If a QMediaService can tune an analog radio device it will implement
59 QRadioTunerControl. This control provides a means to tune a radio device
60 to a specific \l {setFrequency()}{frequency} as well as search \l
61 {searchForward()}{forwards} and \l {searchBackward()}{backwards} for a
62 signal.
63
64 The functionality provided by this control is exposed to application code
65 through the QRadioTuner class.
66
67 The interface name of QRadioTunerControl is \c org.qt-project.qt.radiotunercontrol/5.0 as
68 defined in QRadioTunerControl_iid.
