QT中添加Q_OBJECT和继承QObject出现的问题

直接继承QObject通常是不行的，需要编写一个类继承QObject， 然后再编写实体类继承这个抽象类

例如编写一个Manager继承QObject

#ifndef MANAGER_H
#define MANAGER_H
#include <QObject>
class Manager : public QObject
    Q_OBJECT
public:
    explicit Manager(QObject *parent = 0);
signals:
public slots:
#endif // MANAGER_H
#include "manager.h"
Manager::Manager(QObject *parent) :
    QObject(parent)

MainManager类源码

#include "manager.h"
class MainManage :  public Manager
  Q_OBJECT
public:
    MainManage( );
    ~MainManage();
private slots:
    void on_positionTimerUpdate();
}
