AmFmTuner QML Type

The current band of the tuner.

Available values are:

Holds the id to determine which configuration this feature belongs to.

Once the id has been set, it is possible to change certain values using the InterfaceFrameworkConfiguration API.

See also InterfaceFrameworkConfiguration.

Holds the mode that is used for the autoDiscovery

Available values are:

If necessary, auto discovery is started once the feature creation is completed.

The result of the last autoDiscovery

Available values are:

The current frequency of the tuner.

Indicates whether the feature has been initialized with all the values from the backend.

The property is true once the backend sends the QIfFeatureInterface::initializationDone signal to indicate that all values have now been initialized with values from the backend.

See also isValid and QIfFeatureInterface::initializationDone.

Indicates whether the feature is ready for use.

The property is true if the feature is ready to be used, otherwise false. Not being ready usually indicates that no suitable service object could be found, or that automatic discovery has not been triggered.

The backend still might not have sent all properties yet and is not fully initialized. Use isInitialized instead to know when the feature holds all correct values.

See also QIfServiceObject, discoveryMode, and isInitialized.

The maximum frequency of the current band.

The minimum frequency of the current band.

Holds a list of wildcards to load the preferred backend during auto discovery.

The auto discovery mechanism will automatically search for backends which provide a matching interface for this feature implementation. See startAutoDiscovery() for more information.

In case multiple backends implement the same interface, the list of wildcards can be used to determine the correct one to load.

The wildcards are applied in order to the found backends. If the wildcard matches some backends those backends will be loaded, otherwise the next wildcard is used.

For example: Given an AbstractFeature with two backends, backend_mqtt.so and backend_qtro.so, the property can be set to "*_mqtt*" to always select the backend_mqtt.so backend when available.

true while a scan is in progress, false otherwise.

See also startScan(), stopScan(), scanStarted(), and scanStopped().

Sets the service object for the feature.

As Features only expose the front API facing the developer, a service object implementing the actual function is required. This is usually retrieved through the auto discovery mechanism.

The setter for this property returns false if the QIfServiceObject is already set to this particular instance or the QIfServiceObject isn't accepted by the feature.

See also discoveryMode.

The currently tuned station.

The frequency step size of the current band.

See also stepUp() and stepDown().

A new scan has started and is now running.

See also startScan, stopScan, scanRunning, and scanStopped.

The currently active scan has stopped.

See also startScan, stopScan, scanRunning, and scanStarted.

Seeks the next available Station in downwards direction and tunes it.

If the beginning of the band where hit without finding a station, the search will be continued from the end of the band.

Seeks the next available Station in upwards direction and tunes it.

If the end of the band where hit without finding a station, the search will be continued from the beginning of the band.

Performs an automatic discovery attempt.

The feature tries to locate a single ServiceObject that implements the required interface.

If no ServiceObject is found, the feature remains invalid. If more than one ServiceObject is found, the first instance is used.

This function returns either the type of the backend that was loaded; or an error.

If the discoveryMode is set to QIfAbstractFeature::NoAutoDiscovery, this function does nothing and returns QIfAbstractFeature::NoResult.

Return values are:

See also Dynamic Backend System and QIfServiceManager.

Starts a scan through all available stations.

The scan will seek to the next available station and will stay there for some seconds until it seeks to the next station.

See also stopScan, scanRunning, scanStarted, and scanStopped.

Decreases the frequency by the current bands step size.

Increases the frequency by the current bands step size.

Stops the currently active scan. If no scan is active, this method does nothing.

See also startScan, scanRunning, scanStarted, and scanStopped.

Tunes to the provided station.
