QLineEdit/QTextEdit doesn't receive keyPressEvent on N97

I have a custom widget which inherits from QLinedEdit, in this widget I override event(QEvent * event), keyPressEvent(QKeyEvent *event) and keyReleaseEvent(QKeyEvent *event ). When I debugged the code on N97 device, when I press any key on the keypad the events are delivered as follows:

1. event(QEvent * events) gets called with event type set to KeyRelease.
2. keyReleaseEvent(QKeyEvent *event ) gets called.
and keyPressEvent was never called !!

if I press Enter, BackSpace, action keys, left, right, down, up, the events are delivered as follows:
1. event(QEvent * events) gets called with event type set to KeyPress.
2. keyPressEvent(QKeyEvent *event ) gets called.
3. event(QEvent * events) gets called with event type set to KeyRelease.
4. keyReleaseEvent(QKeyEvent *event ) gets called.
which is correct.

#include <QKeyEvent>
#include <QMessageBox>
#include <QLineEdit>
#include <QTextEdit>
#include <QDebug>

How to reproduce:
class MyWidget : public QLineEdit

{ Q_OBJECT public: MyWidget(QWidget *parent=0); void keyPressEvent(QKeyEvent * event); void keyReleaseEvent(QKeyEvent * event ); bool event(QEvent *event); }

;

MyWidget::MyWidget(QWidget *parent)
:QLineEdit(parent)
{
setText("Hola");
}

void MyWidget::keyPressEvent(QKeyEvent *event)

{ QLineEdit::keyPressEvent(event); }

void MyWidget::keyReleaseEvent(QKeyEvent *event )

{ QLineEdit::keyReleaseEvent(event); }

bool MyWidget::event(QEvent *event ) {
switch( event->type() )

{ case QEvent::KeyPress: QLineEdit::event(event); break; case QEvent::KeyRelease: QLineEdit::event(event); break; default: QLineEdit::event(event); }

}

The same problem appears if I inherits from the QTextEdit
