Member Function Documentation
[virtual] QGeoServiceProviderFactoryV2::~QGeoServiceProviderFactoryV2()
Destroys this QGeoServiceProviderFactoryV2 instance.
[virtual] QNavigationManagerEngine *QGeoServiceProviderFactoryV2::createNavigationManagerEngine(const QVariantMap ¶meters, QGeoServiceProvider::Error *error, QString *errorString) const
Returns a new QNavigationManagerEngine instance, initialized with parameters, which implements navigation functionality.
If error is not nullptr, it should be set to QGeoServiceProvider::NoError on success or an appropriate QGeoServiceProvider::Error on failure.
If errorString is not nullptr, it should be set to a string describing any error which occurred.
The default implementation returns nullptr, which causes a QGeoServiceProvider::NotSupportedError in QGeoServiceProvider.
