Qt - Symbian Mobile - Soft key menus not displaying correctly

I create and show a QWebView with soft key options at the bottom. When I click "Options", a menu shows up, but it's tiny, black, and in the upper left hand corner (it should look like the standard blue soft keys and be directly above them). I followed this example.

//create webview
webView = new QWebView;
webView->setUrl(QString(":html/internal.html"));

//create menu
QAction *option1 = new QAction(tr("Back"), webView);
option1->setSoftKeyRole(QAction::PositiveSoftKey);
    connect(option1, SIGNAL(triggered()), this, SLOT(deleteView()));

//create right softkey action to launch the "options" menu
QAction *option2 = new QAction(tr("Options"), webView);
option2->setSoftKeyRole(QAction::NegativeSoftKey);
    connect(option2, SIGNAL(triggered(), this, SLOT(showMenu()));

QMenu *menuOptions = new QMenu(webView);
menuOptions->addAction(tr("Sub Menu 1"), this, SLOT(aboutView()));
menuOptions->addAction(tr("Sub Menu 2"), this, SLOT(aboutView()));
option2->setMenu(men开发者_如何学JAVAuOptions);

//add softkey menus
QList < QAction* > softKeys;
softKeys.append(option1);
softKeys.append(option2);

webView->addActions(softKeys);
webView->show();

This example works well on simulator and also in phone. It is included in the QTDIR/examples/widgets folder since Qt 4.6.x
