Signals that the frequency band a radio tuner is tuned to has changed.

[pure virtual] void QRadioTunerControl::​cancelSearch()

Stops scanning for a signal.

[pure virtual] QRadioTuner::Error QRadioTunerControl::​error() const

Returns the error state of a radio tuner.

[signal] void QRadioTunerControl::​error(QRadioTuner::Error error)

Signals that an error has occurred.

[pure virtual] QString QRadioTunerControl::​errorString() const

Returns a string describing a radio tuner's error state.

[pure virtual] int QRadioTunerControl::​frequency() const

Returns the frequency a radio tuner is tuned to.

See also setFrequency().

[signal] void QRadioTunerControl::​frequencyChanged(int frequency)

Signals that the frequency a radio tuner is tuned to has changed.

[pure virtual] QPair<int, int> QRadioTunerControl::​frequencyRange(QRadioTuner::Band band) const

Returns a frequency band's minimum and maximum frequency.

[pure virtual] int QRadioTunerControl::​frequencyStep(QRadioTuner::Band band) const

Returns the number of Hertz to increment the frequency by when stepping through frequencies within a given band.

[virtual] bool QRadioTunerControl::​isAntennaConnected() const

Identifies if there is an antenna connected to the device.

Returns true if there is a connected antenna, and false otherwise.

[pure virtual] bool QRadioTunerControl::​isBandSupported(QRadioTuner::Band band) const

Identifies if a frequency band is supported.

Returns true if the band is supported, and false if it is not.

[pure virtual] bool QRadioTunerControl::​isMuted() const

Identifies if a radio tuner's audio output is muted.

Returns true if the audio is muted, and false if it is not.

[pure virtual] bool QRadioTunerControl::​isSearching() const

Identifies if a radio tuner is currently scanning for signal.

Returns true if the tuner is scanning, and false if it is not.

[pure virtual] bool QRadioTunerControl::​isStereo() const

Identifies if a radio tuner is receiving a stereo signal.

Returns true if the tuner is receiving a stereo signal, and false if it is not.

[signal] void QRadioTunerControl::​mutedChanged(bool muted)

Signals that the muted state of a radio tuner's audio output has changed.

[pure virtual] void QRadioTunerControl::​searchAllStations(QRadioTuner::SearchMode searchMode = QRadioTuner::SearchFast)

Starts a scan through the whole frequency band searching all stations with a specific searchMode.

[pure virtual] void QRadioTunerControl::​searchBackward()

Starts a backwards scan for a signal, starting from the current frequency().

[pure virtual] void QRadioTunerControl::​searchForward()
