Methods

Detailed Description

The QIviWindowControl provides an interface to control the physical windows of the vehicle. All properties are exposed through zone objects. The zones are retrieved using the zoneAt method. The QIviWindowControl expects a single backend to be available. It is recommended to use it with discoveryMode set to zoneAt.

Property Documentation

blindMode : QtIviVehicleFunctionsModule::BlindMode

Holds the current mode of the window blind.


blindState : QtIviVehicleFunctionsModule::WindowState

Holds the current state of the window blind.


discoveryMode : enumeration

Holds the mode that is used for the autoDiscovery

Available values are:

ConstantDescription
NoAutoDiscoveryNo auto discovery is done and the ServiceObject needs to be set manually.
AutoDiscoveryTries to find a production backend with a matching interface and falls back to a simulation backend if not found.
LoadOnlyProductionBackendsOnly tries to load a production backend with a matching interface.
LoadOnlySimulationBackendsOnly tries to load a simulation backend with a matching interface.

If needed the auto discovery will be started once the Feature creation is completed.

Note: If you change this property after the Feature is instantiated you need to call startAutoDiscovery() to search for a new Service Object


discoveryResult : enumeration

The result of the last autoDiscovery

Available values are:

ConstantDescription
NoResultIndicates that no auto discovery was started because the feature has already assigned a valid ServiceObject.
ErrorWhileLoadingAn error has happened while searching for a backend with a matching interface.
ProductionBackendLoadedAs a result of the auto discovery a production backend was loaded.
SimulationBackendLoadedAs a result of the auto discovery a simulation backend was loaded.

heater : bool

Indicates whether the window heater is currently running.


heaterMode : QtIviVehicleFunctionsModule::HeaterMode

Holds the current mode of the window heater.


isInitialized : bool

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

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

See also isValid and QIviFeatureInterface::initializationDone.


isValid : bool

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 QIviServiceObject, discoveryMode, and isInitialized.


serviceObject : ServiceObject

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 Service Object is already set to exactly this instance or the Service Object doesn't get accepted by the feature.

See also discoveryMode.


state : QtIviVehicleFunctionsModule::WindowState

Holds the current state of the window.


Method Documentation

close()

Closes the window, if not already in the QIviWindowControl::Closed state.


open()

Opens the window, if not already in the QIviWindowControl::FullyOpen state.


enumeration startAutoDiscovery()

Performs an automatic discovery attempt.

The feature will try to locate a single service object implementing the required interface.

If no service object is found, the feature will stay invalid. If more than one service object is found, the first instance is used.

Either the type of the backend which was loaded or an error is returned.

If the discoveryMode is set to QIviAbstractFeature::NoAutoDiscovery this function will do nothing and return QIviAbstractFeature::NoResult.

Return values are:

ConstantDescription
NoResultIndicates that no auto discovery was started because the feature has already assigned a valid ServiceObject.
ErrorWhileLoadingAn error has happened while searching for a backend with a matching interface.
ProductionBackendLoadedAs a result of the auto discovery a production backend was loaded.
SimulationBackendLoadedAs a result of the auto discovery a simulation backend was loaded.
