Qt Location C++ API

The Location API provides a library for mapping, navigation and place information.

The Qt Location API provides the developer with a set of functions to interact with maps, navigational data and places of interest. This is particularly useful when associated with current position information which can be retrieved via the QtPositioning module.

With the Maps API we can associate a position with a map in various formats supplied by a backend. Then the Places API could be used to populate places on the Map or even specify the current position as a place of interest and associate it with an icon, contact details and other information.

The following table provides links to more detailed information on sections of the Qt Location C++ API.

Maps and NavigationDisplaying maps and finding routes.
PlacesSearching for and managing points of interest.

Manages an operation started by an instance of QGeoRoutingManager

QGeoRouteSegment

Represents a segment of a route

QGeoRouteRequest

Represents the parameters and restrictions which define a request for routing information
