Member Function Documentation

[virtual] QGeoServiceProviderFactoryV2::~QGeoServiceProviderFactoryV2()

Destroys this QGeoServiceProviderFactoryV2 instance.

[virtual] QNavigationManagerEngine *QGeoServiceProviderFactoryV2::createNavigationManagerEngine(const QVariantMap &parameters, 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.
