The identifying string for this module is QtPositioning . To use the QML from this module, include the following import statement in the QML file:
import QtPositioning 5.12
Position information can come from a variety of sources including satellites, Wi-Fi, text files and so on. The position is described by the latitude, longitude, and the altitude in meters. For more information, see the Wikipedia page on Geographic Coordinates .
The QML position is stored in a coordinate which contains the latitude, longitude and altitude of the device. The 定位 contains this coordinate and adds an address, and also has a bounding box which defines the recommended viewing region when displaying the location.
Now that the device has a position, with regular updates the API can determine the speed and heading of the device. It can also define a box-shaped or circular region that triggers notifications when the device either leaves or enters that region.
More detailed information on retrieving the current position can be found under Location Positioning via QML .
| coordinate | Type represents and stores a geographic position |
