Problem with QTimer

[hosseinyounesi]

This is what I wrote to make a simple timer.
openSuse 11, Qt 4.5, Qt Creator, Qt GUI App

It doesn't work, I mean when I try to execute it "Hi" doesn't appear on Konsole. I tried to debug it in the constructor of the class, but gdb never goes there.
Thanks for your help

MyObject.h

#include <QtCore/QObject>
#include <QtCore/QTimer>
class MyObject : public QObject
{
Q_OBJECT
public:
    MyObject();
private:
    QTimer *timer;
 
private slots:
    void timerEvent();
};

#include <QtCore/QObject>
#include <QtCore/QTimer>
class MyObject : public QObject
{
Q_OBJECT
public:
    MyObject();
private:
    QTimer *timer;

private slots:
    void timerEvent();
};
