QRadioTunerControl

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

Detailed Description

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 org.qt-project.qt.radiotunercontrol/5.0 as defined in QRadioTunerControl_iid .
