Maps and Navigation provides C++ utilities for geocoding (finding a geographic coordinate from a street address) and navigation (including driving and walking directions).
Currently it is not possible to interact with maps via C++. Mapping applications must use the Maps and Navigation (QML) API.
In C++, an address-to-coordinate query is performed using the geocode() method of the QGeoCodingManager class. For coordinate-to-address queries, the reverseGeocode() method is available on the same class. Instances of QGeoCodingManager are available via QGeoServiceProvider.
Key Classes
| QGeoServiceProvider | Provides a QGeoCodingManager instance ready for use. |
| QGeoCodingManager | Accepts queries and produces QGeoCodeReply objects. |
| QGeoCodeReply | Contains the results of a geocoding query. |
In C++, a route query is performed using the calculate() method of the QGeoRoutingManager class. The returned route reply can contain multiple routes to the same destination.
