Qt里通过传递函数指针实现动态绑定信号/槽

// test.h

#include <QObject>

class QTimer;

class Test:public QObject

{
 
 

Q_OBJECT

public:

    Test(QObject * parent = 0);

    ~Test();

    void startTimer(int interval);

    void connectQTimer(void(Test::*pf)());

public slots:

    void onTimeout();

    void onPrintOut();
