VSCode下载【Open】插件，这样右击文件能以默认应用打开文件，这样右击打开【.ui】文件，就能在QT的【designer.exe】中打开了。
利用QT的【uic.exe】将【.ui】转换为【.h】C++格式头文件，然后带有Q_OBJECT宏的文件需要被QT的【moc.exe】MOC成CPP文件。然后gcc或g++就能编译了。
VSCode需要配置的json文件主要有【c_cpp_properties.json】、【launch.json】、【tasks.json】。
【c_cpp_properties.json】中需要配置头文件路径、编译器g++.exe路径、C标准C11、C++标准C++11。
【launch.json】中需要配置是否外置控制台、生成的EXE文件路径及名称、最后一个任务的名称。
【tasks.json】中需要配置详细的任务，如EXE加入图标、QT ui文件转换为C++文件、带Q_OBJECT宏的文件需要MOC成CPP文件、g++编译、删除图标.o文件。g++编译，要把所有的CPP和C文件都包括进去，头文件目录、库目录、库基础名称也要包含。若是CMD直接打指令操作则设置command为 ""。多个task之间使用【dependsOn】来指定顺序。
下面是一个配置样板：
