Qt Positioning

The Qt Positioning API provides positioning information via QML and C++ interfaces.

Currently, the API is supported on Android, iOS, macOS, Linux, and Windows (with GPS receivers exposed as a serial port providing NMEA sentences or using Windows.Devices.Geolocation).

Overview

The Qt Positioning API lets you to determine a position by using a variety of possible sources, including satellite, wifi, or text files. That information can then be used to, for example, determine a position on a map. In addition, you can use to the API to retrieve satellite information and perform area based monitoring.

Using the Module

QML API

The QML types of the module are available through the QtPositioning import. To use the types, add the following import statement to your .qml file:

import QtPositioning

C++ API

Using a Qt module requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.

Building with CMake

Use the find_package() command to locate the needed module component in the Qt6 package:

find_package(Qt6 REQUIRED COMPONENTS Positioning)
target_link_libraries(mytarget PRIVATE Qt6::Positioning)

For more details, see the Build with CMake overview.

Building with qmake

To configure the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:

QT += positioning
