The Qt Location API helps you create viable mapping solutions using the data available from some of the popular location services.
Qt Location API 能夠：
To load the Qt Location module, add the following statement to your .qml files
import QtPositioning 5.12 import QtLocation 5.12
The QtLocation QML module depends on the QtPositioning QML module. Therefore every QML application that imports the QtLocation QML module must always import the QtPositioning module as well.
對於 include 當前使用情況適當 header 的 C++ 工程，例如，使用路由的應用程序可以使用
#include <QGeoRoute>
.pro 文件應有 location 添加關鍵詞
QT += location
The API is split into sub-modules, which provide QML and C++ interfaces for specific purposes. They focus mainly on Map and Place information. The required position data can be retrieved using the QtPositioning 模塊。
The Places submodule is the natural complement to Positioning, providing a source of geographical data about Places of Interest (POI). Besides the source information, the API provides information about the location, size, and other related information about a POI. The Places API can also retrieve images, reviews, and other content related to a place.
| Places introduction: | for QML | for C++ |
The module provides the QML and C++ alternatives for maps and navigation. The C++ alternative provides utility classes to get geocoding (finding a geographic coordinate from a street address) and navigation (including driving and walking directions) information, whereas its QML counterpart provides UI components to render the information.
