QWebView reimp. contextMenuEvent takes no effect

[tucnak]

Is it for WebKit forum? I've thought that my issue is about QWidget more, so, I've posted it here.

I have a code:
@
class ExtendedWebView : public QWebView
{
public:
ExtendedWebView (QWidget *parent = 0) :
QWebView(parent),
m_contextMenu(new QMenu(this)),
m_copyAction(new QAction(this))
{
m_copyAction->setText(tr("Copy"));
m_copyAction->setIcon(QIcon(":/icons/edit-copy.png"));
m_copyAction->setIconVisibleInMenu(true);
m_copyAction->setToolTip(tr("Copy selected content"));
m_contextMenu->addAction(m_copyAction);

#if !(QT_VERSION >= 0x040700 && QT_VERSION < 0x040800)
QAction *hotCopyAction = pageAction(QWebPage::Copy);
hotCopyAction->setShortcut(QKeySequence::Copy);
}
#endif

protected:
void contextMenuEvent(QContextMenuEvent *event)
{
qDebug() << "called";
m_copyAction->setEnabled(!selectedHtml().isEmpty());
m_contextMenu->setVisible(true);
m_contextMenu->exec(event->globalPos());
}

#if (QT_VERSION >= 0x040700 && QT_VERSION < 0x040800)
void keyPressEvent(QKeyEvent *event)
{
if(event->modifiers() == Qt::ControlModifier && event->key() == Qt::Key_C) {
const QString text = selectedText();
if (!text.isEmpty()) {
QClipboard *clipboard = qApp->clipboard();
clipboard->setText(text);
} else {
QWebView::keyPressEvent(event);
}
}
}

#endif

private:
QMenu *m_contextMenu;
QAction *m_copyAction;
};
@

Menu is not executed on right-click on the widget.
