Questions tagged [qtlocation]

The Qt Location API helps to create viable mapping solutions using the data available from some of the popular location services.

The Qt Location API enables the user to:

  • access and present map data,
  • support touch gesture on a specific area of the map,
  • query for a specific geographical location and route,
  • add additional layers on top, such as polylines and circles,
  • and search for places and related images.

The module provides both a C++ API as well as a QML API.
