Detailed Description
The functionality provided by this control is exposed to application code through the QRadioData class.
The interface name of QRadioDataControl is org.qt-project.qt.radiodatacontrol/5.0 as defined in QRadioDataControl_iid.

Member Function Documentation
[protected] QRadioDataControl::QRadioDataControl(QObject *parent = nullptr)
Constructs a radio data control with the given parent.
[signal] void QRadioDataControl::alternativeFrequenciesEnabledChanged(bool enabled)
Signals that the alternative frequencies setting has changed to the value of enabled.
[signal] void QRadioDataControl::error(QRadioData::Error error)
Signals that an error has occurred.
Note: Signal error is overloaded in this class. To connect to this signal by using the function pointer syntax, Qt provides a convenient helper for obtaining the function pointer as shown in this example:
connect(radioDataControl, QOverload<QRadioData::Error>::of(&QRadioDataControl::error), [=](QRadioData::Error error){ /* ... */ });
[signal] void QRadioDataControl::programTypeChanged(QRadioData::ProgramType programType)
Signals that the Program Type programType has changed
[signal] void QRadioDataControl::programTypeNameChanged(QString programTypeName)
Signals that the Program Type Name programTypeName has changed
[signal] void QRadioDataControl::radioTextChanged(QString radioText)
Signals that the Radio Text radioText has changed
[signal] void QRadioDataControl::stationIdChanged(QString stationId)
Signals that the Program Identification stationId has changed
[signal] void QRadioDataControl::stationNameChanged(QString stationName)
Signals that the Program Service stationName has changed
[virtual] QRadioDataControl::~QRadioDataControl()
Destroys a radio data control.
[pure virtual] QRadioData::Error QRadioDataControl::error() const
Returns the error state of a radio data.
[pure virtual] QString QRadioDataControl::errorString() const
Returns a string describing a radio data's error state.
[pure virtual] bool QRadioDataControl::isAlternativeFrequenciesEnabled() const
Returns true if Alternative Frequency is currently enabled
[pure virtual] QRadioData::ProgramType QRadioDataControl::programType() const
Returns the current Program Type
[pure virtual] QString QRadioDataControl::programTypeName() const
Returns the current Program Type Name
[pure virtual] QString QRadioDataControl::radioText() const
Returns the current Radio Text
[pure virtual] void QRadioDataControl::setAlternativeFrequenciesEnabled(bool enabled)
Sets the Alternative Frequency to enabled
See also isAlternativeFrequenciesEnabled().
[pure virtual] QString QRadioDataControl::stationId() const
Returns the current Program Identification
[pure virtual] QString QRadioDataControl::stationName() const
Returns the current Program Service
