使用方式很简单，include头文件siglslot.h, 所有类在sigslot namespace中。

 

#include <iostream>
#include "sigslot.h"
using namespace std;
using namespace sigslot;

class window
{
public:
    signal0<> _lclicksig;
    signal1<int> _paintsig;
};

class foo : public has_slots<>
{
public:
    void lbuttondown()
    {
        cout<<"left button clicked"<<endl;
    }
    void paint(int i)
    {
        cout<<"i = "<<i<<endl;
    }
};

int main()
{
    window w;
    foo f;
    w._lclicksig.connect(&f, &foo::lbuttondown);
    w._paintsig.connect(&f, &foo::paint);
    w._lclicksig();
    w._paintsig(100);

    return 0;
}
