Detailed Description

Qt IVI Vehicle Functions provides C++ API.

Getting Started

To link against the Qt IVI Vehicle Feature module, add this line to your qmake project file:

QT += ivivehiclefunctions

To use Qt IVI Vehicle Functions C++ classes in your application, use the following include statement:

#include <QtIviVehicleFunctions>

Note: If you are only using a few classes from this module, it's recommended to include only those specific classes instead of the whole module.

To use feature elements, simply include the header file and instantiate the element:

#include <QtIviVehicleFunctions/QIviClimateControl>
 QIviClimateControl* m_climateControl;
 m_climateControl = new QIviClimateControl(this);

In order to trigger the auto discovery mechanism, call the startAutoDiscovery method. This will load the appropriate backend and set a service object for the feature element. Please notice that calling this method sets the autoDiscovery property to true. To use dynamic services, simply do not call this method.


After the startAutoDiscovery method has been called, the isValid property can be used to determine if a backend was found or not.

if (!m_climateControl->isValid())
   QMessageBox::critical( ... ); // Take action here

Climate general values can be get and set directly by the feature instance:

if (!m_climateControl->airConditioningEnabled());

Some features, like climate control, are divided into several climate zones. The names of the available zones can be checked using QIviAbstractZonedFeature::availableZones():

QStringList zones = m_climateControl->availableZones();

You can use QIviAbstractZonedFeature::zoneAt() to access zone functions:


Looping zones is done with QIviAbstractZonedFeature::zones():

const auto zones = m_climateControl->zones();
for (QClimateControl *z : zones)
    if (z->zone() == "FrontLeft")
