sigslot库

官方地址

在vs2013中使用

包含头文件

#include "sigslot.h"

改动：

//在sigslot.h的420,将：typedef sender_set::const_iterator const_iterator;    //改为：typedef typename sender_set::const_iterator const_iterator;

基本使用：

signal0~signal8：信号类：作为类成员

class mySg    {        sigc::signal0<> sg1; // 无参数 sigc::signal2
    
      sg2; // 2个参数 }

connection
槽函数：作为类成员，类需要继承has_slots<>，且槽函数的返回值必须是void类型

class mySlot: public : has_slots<>    {    public:        void on_func1(){}                       // 无参数，与信号对应 void on_func2(char*, double)(){} // 2个参数 }; mySg sig; mySlot slt; sig.sg1.conncent(&slt,&mySlot::on_func1); sig.sg2.conncent(&slt,&mySlot::on_func2);

disconnection
解除连接：可以使用disconnect()和disconnect_all()

sig.sg1.disconnect(&slt);    sig.sg1.disconnect_all();

emiting
发送信号：可以直接使用()运算符，也可以调用signal的emit函数

sig.sg1.emit();    sig.sg2("str",0.1);

实例：

#include 
    
     #include 
     
      #include 
      
       #include 
       
        using namespace std; #include "sigslot.h" using namespace sigslot; #define pause_wait() {std::cout << "\nPlease press any key to continue.\n";_getch();} // class enum ObjState{Normal = 0, Hidden = 1}; class ObjectBase : public has_slots<> { public: ObjectBase(){ px = 0; py = 0; state = Normal; } ObjectBase(const int &x, const int &y):px(x), py(y){ state = Normal; } ~ObjectBase(){}; void onMoveBy(const int &x, const int &y){px += x; py += y;} void onResize(const int &x, const int &y){px = x; py = y;} void onSetState(ObjState s){ this->state = s;} void onPrintState() { if(state == Normal) std::cout << "Normal" << std::endl; else if(state == Hidden) std::cout << "Hidden" << std::endl; else std::cout << "Error: error state value" << std::endl; } const int& getX(){ return px;} const int& getY(){ return py;} const char* getState() { if(state == Normal) return "Normal"; else if(state == Hidden) return "Hidden"; else return nullptr; } private: ObjState state; int px; int py; }; class Control { public: signal2
        
          moveBy; signal2
         
           resize; signal1
          
            setState; signal0<> printState;; }; int main(int argc, char* argv[]) { ObjectBase obj(10,10); Control ctrl; #if(1) ctrl.moveBy.connect(&obj, &ObjectBase::onMoveBy); ctrl.resize.connect(&obj, &ObjectBase::onResize); ctrl.setState.connect(&obj, &ObjectBase::onSetState); ctrl.printState.connect(&obj, &ObjectBase::onPrintState); //ctrl.moveBy.disconnect(&obj); //ctrl.moveBy.disconnect_all(); // start pro loop PRO_Start: while(true) { system("cls"); cout << "Object Information" << endl; cout << "\t Position_x: " << obj.getX() << endl; cout << "\t Position_y: " << obj.getY() << endl; cout << "\t State: " << obj.getState() << endl; cout << "\n"; cout << "\t m: move object \n" "\t r: resize object \n" "\t s: set object state \n" "\t p: print object state \n" << endl; cout << "Input:"; char ch = getchar(); switch(ch) { case 'm': // move ctrl.moveBy(10,10); break; case 'M': ctrl.moveBy.emit(-20,-20); break; case 'R': case 'r': // resize ctrl.resize.emit(0, 0); break; case 'P': case 'p': // printState goto PRO_PrintState; break; case 's': // setState ctrl.setState(Normal); break; case 'S': ctrl.setState.emit(Hidden); break; case 'Q': case 'q': // exit goto PRO_Exit; break; default: break; } } PRO_PrintState: ctrl.printState.emit(); pause_wait(); goto PRO_Start; #endif pause_wait(); PRO_Exit: return 0; }

sigc++库

官方地址

编译

可以在下载已经编好的库文件，2.8.0版

注意1：在用高版本编译时，如2.8.0，可能会提示找不到msvc_recommended_pragmas.h，可以在vs的

属性 -> C/C -> 高级 -> 强制包含文件

去掉msvc_recommended_pragmas.h，或者添加一个msvc_recommended_pragmas.h文件，在的源代码时已经放入了该文件。

注意2：在使用高版本(如2.9.7)编译时，若提示找不到slot.cc等文件，可以使用低版本中的放入相应位置即可。

在vs中使用

* 项目 -> VC++目录 -> 包含目录： 添加 sigc++所在的目录* 添加下列代码：

#include 
    
             #ifdef _DEBUG            #pragma comment(lib,"sigcd.lib")        #else #pragma comment(lib,"sigc.lib") #endif

基本使用：

signal
信号类：可以作为其它类成员，也可直接定义

//返回值: int，2个参数:char*, double，参数个数可以直接指定    sigc::signal
    
      sg1; sigc::signal2
     
       sg2; class mySg { sigc::signal2
      
        sg3; }

connection
连接槽函数，作为类成员时，要继承sigc::trackable；
ptr_fun, ptr_fun0~7 : 连接全局函数；
mem_fun, mem_fun0~7 : 连接类成员函数；
ptr_fun,mem_fun与signal之间只要参数类型对应就可连接，并非一定要数字对应（如：ptr_fun3并非一定要与signal3对应连接）

sigc::connection ccSg1 = sg1.connect(sigc::ptr_fun(&func1));    class mySlot: public : sigc::trackable    {    public:        int func2(char*, double)(){} } obj; sigc::connection ccSg2 = sg2.connect(sigc::mem_fun2(obj,&mySlot::func)); class mySg: public : sigc::trackable { mySg(){auto ccIter_Sg3 = sg3.connect(sigc::mem_fun(*this,&mySg::on_func));} sigc::signal2
    
      sg3; int on_func(char*, double)(){} }

disconnection
如果不需要解连接，可以不用定义sigc::connection

ccSg1.disconnect();    ccSg2.disconnect();

emiting
// 发送信号：调用signal的emit函数

sg1.emit("str",0.1);    sg2.emit("str",0.1);
