Hi Maysoon88,
It is simple if you are aware of using Qt and Symbian C++ together. What you have to do is to use the QTimer class and create a slot which will get called at regular instants to reset the inactivity.To help you further, let me make it more clear by writing the whole procedure :
1- Include the required headers

#include <eikenv.h> //its a Symbian C++ header that includes the User class 
#include <QTimer>

2- Declare a slot in the .h file :

private slots:
    void reset_timer();

3- Define this slot in respective .cpp file :

void MainWindow::reset_timer()
{
#if defined(Q_WS_S60)
    User::ResetInactivityTime();
#endif
}

4- Thats it. Now, call this slot at regular instants by using QTimer Class :

    QTimer *timer = new QTimer(this);
    connect(timer, SIGNAL(timeout()), this, SLOT(reset_timer()));
    timer->start(5000); //keep calling the SLOT after 5000 ms

Thats it. Hope it helps

Best Regards,

Qt Mobility 1.0 supports that ....
QSystemScreenSaver *sss=new QSystemScreenSaver ( this );
sss->setScreenSaverInhibit();
