Detailed Description
Note: There are no source or binary compatibility guarantees for the backend classes. The API is only guaranteed to work with the Qt version it was developed against. API changes will however only be made in minor releases. (6.6, 6.7, and so on.)
Implementers must provide a unique combination of providerName() and providerVersion() per plugin.
The other functions should be overridden if the plugin supports the associated set of functionality.
Member Function Documentation
[virtual noexcept] QGeoServiceProviderFactory::~QGeoServiceProviderFactory()
Destroys this QGeoServiceProviderFactory instance.
[virtual] QGeoCodingManagerEngine *QGeoServiceProviderFactory::createGeocodingManagerEngine(const QVariantMap ¶meters, QGeoServiceProvider::Error *error, QString *errorString) const
Returns a new QGeoCodingManagerEngine instance, initialized with parameters, which implements the location geocoding 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.
[virtual] QPlaceManagerEngine *QGeoServiceProviderFactory::createPlaceManagerEngine(const QVariantMap ¶meters, QGeoServiceProvider::Error *error, QString *errorString) const
Returns a new QPlaceManagerEngine instance, initialized with parameters, which implements the place searching 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.
[virtual] QGeoRoutingManagerEngine *QGeoServiceProviderFactory::createRoutingManagerEngine(const QVariantMap ¶meters, QGeoServiceProvider::Error *error, QString *errorString) const
Returns a new QGeoRoutingManagerEngine instance, initialized with parameters, which implements routing 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.
[virtual] void QGeoServiceProviderFactory::setQmlEngine(QQmlEngine *engine)
Notify the plugin when the qml engine is ready. In this moment the plugins can use it to register Image Providers.
The default implementation does nothing.
