error : Class declarations lacks Q_OBJECT macro

直译是：类声明没有Q_OBJECT 宏。
class CError1 : public QObject
{

signals:
   void OnButClicked();
};

class CError2 : public QObject
{
signals:
   void OnButClicked();
};

class CError1 : public QObject
{
   Q_OBJECT
signals:
   void OnButClicked();
};

类声明加上Q_OBJECT就好了。

class CError1 : public QObject
{
   Q_OBJECT
signals:
   void OnButClicked();
};

class CError2 : public QObject
{
   Q_OBJECT
signals:
   void OnButClicked();
};
class CError2 : public QObject
{
   Q_OBJECT
signals:
   void OnButClicked();
};
