Qt Positioning C++ 类

Positioning 模块凭借 QML 和 C++ 接口提供位置信息。更多...

类

QGeoAddress	表示 QGeoLocation 的地址
QGeoAreaMonitorInfo	表示接近要监视区域或地区的参数
QGeoAreaMonitorSource	Enables the detection of proximity changes for a specified set of coordinates
QGeoCircle	Defines a circular geographic area
QGeoCoordinate	Defines a geographical position on the surface of the Earth
QGeoLocation	Represents basic information about a location
QGeoPath	定义地理路径
QGeoPolygon	Defines a geographic polygon
QGeoPositionInfo	包含特定时间点的全局位置、方向和速度的有关聚合信息
QGeoPositionInfoSource	Abstract base class for the distribution of positional updates
QGeoPositionInfoSourceFactory	Factory class used as the plugin interface for external providers of positioning data
QGeoRectangle	Defines a rectangular geographic area
QGeoSatelliteInfo	包含有关卫星的基本信息
QGeoSatelliteInfoSource	Abstract base class for the distribution of satellite information updates
QGeoShape	Defines a geographic area
QNmeaPositionInfoSource	Positional information using a NMEA data source
QNmeaSatelliteInfoSource	Satellite information using an NMEA data source

要加载 Qt Positioning 模块，添加以下语句到 .qml 文件

import QtPositioning

For C++ projects include the header appropriate for the current use case, for example applications using routes may use

#include <QGeoCoordinate>

使用 Qt 模块要求直接或透过其它依赖链接到模块库。一些构建工具为此有贡献支持，包括 CMake and qmake .

使用 find_package() 命令去定位所需模块组件，在 Qt6 包：

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

要配置采用 qmake 构建模块，添加模块作为值为 QT 变量在工程的 .pro 文件：

QT += positioning
