Hello,

I am trying to inherit QApplication in my code but unfortulately i am unable to connect with SLOTS,

I have commented the Q_OBJECT macro coz when i uncomment that macro it creates vtable problem to me.

Any idea about this problem please help.

.h file
Qt Code: 
  1. #include <QtGui/QApplication>
  2. #include <QtCore/QCoreApplication>
  3.  
  4. #include <QObject>
  5. #include <QEvent>
  6. #include <QTimer>
  7. #include <QDebug>
  8.  
  9. class InactivityWatcher : public QApplication
  10. {
  11.     //    Q_OBJECT
  12.  
  13. public:
  14.     explicit InactivityWatcher(int &argc, char *argv[]);
  15.  
  16. public:
  17.     QTimer m_timer;
  18.  
  19. protected slots:
  20.     void appIdleForFiveSecs();
  21.  
  22.     virtual bool notify(QObject *receiver, QEvent *event);
  23.     virtual bool event (QEvent * e);
  24.  
  25. };
