Qt Interface Framework Vehicle Functions C++ Classes

Detailed Description

Qt Interface Framework Vehicle Functions provides C++ API.

Getting Started

To link against the Qt Interface Framework Vehicle Feature module, use the following directive:

Using CMake:

find_package(Qt6 COMPONENTS IfVehicleFunctions REQUIRED)
target_link_libraries(mytarget PRIVATE Qt6::IfVehicleFunctions)

Using qmake:

QT += ifvehiclefunctions

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

#include <QtIfVehicleFunctions>

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

#include <QtIfVehicleFunctions/QIfClimateControl>
...
QIfClimateControl* m_climateControl;
m_climateControl = new QIfClimateControl(this);

In order to trigger the auto discovery mechanism, call the startAutoDiscovery method. This will load the appropriate back end 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.

m_climateControl->startAutoDiscovery();

After the startAutoDiscovery method has been called, the isValid property can be used to determine if a back end 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());
   m_climateControl->setAirConditioningEnabled(true);

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

QStringList zones = m_climateControl->availableZones();

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

m_climateControl->zoneAt("FrontLeft")->setSeatHeater(false);

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

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