需求概述,从服务器用protobuf,接受消息,但是本身protobuf本身结构很大,使用自定义class接收protobuf消息,存储,并实现转json。数据结构与算法分离,使用jsoncpp,boost库。 上结果 上代码 main.cpp//测试使用 CMakeLists.txt ...golang-json, 源码解释struct转json时,struct的属性字段需要大写才能
AI代码解释 /// This class defines the Toy struct type. It represents a collection of/// element types. All derived types in MLIR must inherit from the CRTP class/// 'Type::TypeBase'. It takes as template parameters the concrete type/// (StructType), the base class to use (Type), a...
将Base Class修改成QWidget,方框中的内容可以不勾,个人习惯 ui文件中添加opengl控件并提升为OpenGLWidget(可以另外修改成其他的名字,与之后在文件中新建的类名一致即可),控件具体名称可以不管 添加新类,名称openglwidget(与刚才提升的类名一致,但小写) main.cpp, invisual.cpp, invisual.h文件全保持不变,对openglwi...

extern keyword in C extern 可以告诉编译器,在编译单元的某处,有这么一个全局变量。 int i; 是变量的定义 extern int i; 是变量的声明,所以,extern 不能初始化变量。 声明和定义 声明不产生代码 函数原型 变量、结构、宏、枚举、类型声明 inline函数 ...
