c/c++程序引入信号槽方法

1.#include <QObject>;

2.Q_OBJECT;

3.:public QObject;

eg:

#include <QObject>
//注意：如果缺少3，则会报错Error: Class //contains Q_OBJECT macro but does not //inherit from QObject
class TestAddSignalSlotFunction:public QObject
{
    Q_OBJECT
public:
    TestAddSignalSlotFunction();

public slots:
    void slotReceiveTest();

};
