Detailed Description▲
The radio data object will emit signals for any changes in radio data. You can enable or disable alternative frequency with setAlternativeFrequenciesEnabled().
You can get a QRadioData instance fromt the radioData property from a QRadioTuner instance.
radio = new QRadioTuner;
radioData = radio->radioData();Alternatively, you can pass an instance of QRadioTuner to the constructor to QRadioData.

Member Function Documentation▲
[explicit] QRadioData::QRadioData(QMediaObject *mediaObject, QObject *parent = nullptr)▲
Constructs a radio data based on a mediaObject and parent.
The mediaObject should be an instance of QRadioTuner. It is preferable to use the radioData property on a QRadioTuner instance to get an instance of QRadioData.
During construction, this class is bound to the mediaObject using the bind() method.
[virtual] QRadioData::~QRadioData()▲
Destroys a radio data.
void QRadioData::alternativeFrequenciesEnabledChanged(bool enabled)▲
Signals that automatically tuning to alternative frequencies has been enabled or disabled according to enabled.
Notifier signal for property alternativeFrequenciesEnabled.
QMultimedia::AvailabilityStatus QRadioData::availability() const▲
Returns the availability of the radio data service.
A long as there is a media service which provides radio functionality, then the availability will be that of the radio tuner.
QRadioData::Error QRadioData::error() const▲
void QRadioData::error(QRadioData::Error error)▲
Signals that an error occurred.
QString QRadioData::errorString() const▲
[override virtual] QMediaObject *QRadioData::mediaObject() const▲
void QRadioData::programTypeChanged(QRadioData::ProgramType programType)▲
Signals that the Program Type code has changed to programType
Notifier signal for property programType.
void QRadioData::programTypeNameChanged(QString programTypeName)▲
Signals that the Program Type Name has changed to programTypeName
Notifier signal for property programTypeName.
void QRadioData::radioTextChanged(QString radioText)▲
Signals that the Radio Text property has changed to radioText
Notifier signal for property radioText.
[override virtual protected] bool QRadioData::setMediaObject(QMediaObject *mediaObject)▲
Reimplements: QMediaBindableInterface::setMediaObject(QMediaObject *object).

void QRadioData::stationIdChanged(QString stationId)▲
Signals that the Program Identification code has changed to stationId
Notifier signal for property stationId.
void QRadioData::stationNameChanged(QString stationName)▲
Signals that the Program Service has changed to stationName
Notifier signal for property stationName.
