qwsEventFilter implementation

[lisarden]

I try to intercept keyboard events using qwsEventFilter. First of all I must mention that currently I use Qt-creator on X86 Ubuntu and may be this causes problems..

What I did:
myapp.h

class MyApp : public QApplication
{
public:
    MyApp(int &argc, char **argv ) : QApplication( argc, argv ) {};
 
    bool qwsEventFilter(QWSEvent * event);
};

class MyApp : public QApplication
{
public:
    MyApp(int &argc, char **argv ) : QApplication( argc, argv ) {};

    bool qwsEventFilter(QWSEvent * event);
};

myapp.cpp

#include "myapp.h"
 
bool MyApp::qwsEventFilter(QWSEvent *e)
{
    if(e->type == QEvent::KeyPress) {
        qDebug("pressed");
    }
    else if (e->type == QEvent::KeyRelease ) {
        qDebug("released");
    }
    return false;
}

#include "myapp.h"

bool MyApp::qwsEventFilter(QWSEvent *e)
{
    if(e->type == QEvent::KeyPress) {
        qDebug("pressed");
    }
    else if (e->type == QEvent::KeyRelease ) {
        qDebug("released");
    }
    return false;
}

main.c

#include <QtGui/QApplication>
#include "myapp.h"
#include "qt-linphone.h"
 
int main(int argc, char *argv[])
{
    MyApp a(argc, argv);
    Widget w;
    w.show();
 
    return a.exec();
}

#include <QtGui/QApplication>
#include "myapp.h"
#include "qt-linphone.h"

int main(int argc, char *argv[])
{
    MyApp a(argc, argv);
    Widget w;
    w.show();

    return a.exec();
}

if I run the application with -qws and then hit any button on a keyboard I don't see "pressed"/"released". What is wrong with my code? May be Qt creator can handle QWS related code? Anyway I tried to use x11EventFIlter and it didn't even compile because of absence of XEvent definition..
