Below is the code

klinkiconview.h:

#ifndef KLINKICONVIEW_H#define KLINKICONVIEW_H
#include <kiconview.h>
*class* KAction;
*/****@author** Nikhil Marathe***/**class* KlinkIconView : *public* KIconView
{
    *Q_OBJECT**public*:
    KlinkIconView(QWidget* parent=0, const char* name=0);

    ~KlinkIconView();


*private* *slots*:
    void showContextMenu(QIconViewItem *item, const QPoint & pos);
};
#endif


klinkiconview.cpp:

#include "klinkiconview.h"

#include <qaction.h>

#include <kpopupmenu.h>

KlinkIconView::KlinkIconView(QWidget* parent, const char* name):
KIconView(parent, name)
{

    connect(this, SIGNAL(contextMenuRequested(QIconViewItem*, const QPoint&)),
                this, SLOT(showContextMenu(QIconViewItem*, const QPoint& )));
}


KlinkIconView::~KlinkIconView()
{
}

#include "klinkiconview.moc"

/*!
    \fn KlinkIconView::showContextMenu(QIconViewItem *item, const QPoint & pos)
 */
void KlinkIconView::showContextMenu(QIconViewItem * item, const QPoint & pos)
{
    qWarning("HELLO");
    KPopupMenu conMenu(this);
    QAction *newKlinkAct = new QAction("New Klink", 'N', 0);
    newKlinkAct->addTo(&conMenu);
    conMenu.exec(pos);
}



When i remove Q_OBJECT and the slots it is displayed fine.
But if i add the Q_OBJECT macro i get an empty window without an iconview.
There are no errors during compilation.
Qt version - 3.3
Kde version - 3.4
