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 REQUIRED COMPONENTS Positioning) 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
