QRadioDataControl Class

Member Function Documentation

[protected] QRadioDataControl::QRadioDataControl(QObject *parent = nullptr)

Constructs a radio data control with the given parent.

[virtual] QRadioDataControl::~QRadioDataControl()

Destroys a radio data control.

[signal] void QRadioDataControl::alternativeFrequenciesEnabledChanged(bool enabled)

Signals that the alternative frequencies setting has changed to the value of enabled.

[pure virtual] QRadioData::Error QRadioDataControl::error() const

Returns the error state of a radio data.

[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){ /* ... */ });
