Can't get menu bar in Qt Quick Components, using C++ and QQmlApplicationEngine

[Tory Gaurnier]

Now that Ubuntu finally has Qt 5.2, I'm playing with Qt Quick Components, and right now I'm having issues trying to get the menu bar to show, when I try to implement the menubar I get this message:

appmenu-qt: handleReparent 128 The given QWindow has no QMenuBar assigned

This is how I'm launching my Qml from C++:
@
// First initialize Qt Application
QGuiApplication app(argc, argv);
// Second initialize config singleton
Config::init();
QQmlApplicationEngine engine;
engine.load(QUrl::fromLocalFile(config->getBinDir() + "/qml/main.qml"));
QObject *topLevel = engine.rootObjects().value(0);
QQuickWindow mainWindow = qobject_cast<QQuickWindow>(topLevel);

mainWindow->show();
return app.exec();
@

And this is the Qml I have so far:
@
import QtQuick.Controls 1.1
import QtQuick.Dialogs 1.1
import QtQuick 2.2

ApplicationWindow {
visible: true
width: 640
height: 480
minimumWidth: 400
minimumHeight: 300

title: "MyApp"

// Actions for menu items
Item {
id: globalActions

Action {
id: quitAction
text: i18n.tr("Quit");
onTriggered: Qt.quit();
}

Action {
id: prefAction
text: i18n.tr("Preferences");
//onTriggered: TODO - LAUNCH PREFERENCES
}

Action {
id: aboutAction
text: i18n.tr("About");
//onTriggered: TODO - LAUNCH ABOUT
}
}

MessageDialog {
id: aboutBox
title: "MyApp"
text: "This is a test app for Qt Quick Components"
icon: StandardIcon.Information
}

menuBar: MenuBar {
Menu {
title: "&File"
MenuItem { action: quitAction }
}
Menu {
title: "&Edit"
MenuItem { action: prefAction }
}
Menu {
title: "&Help"
MenuItem { action: aboutAction }
}
}
}

Can you check, whether your window is really a window?

@ QQuickWindow * window = qobject_cast<QQuickWindow *>(topLevel);
if ( !window ) {
qWarning("Error: Your root item has to be a Window.");
return -1;
}@

My code is very similar to yours, except for the Config::init command. I previously had trouble with doing init stuff in an order that the QT framework somehow did not like.

[Tory Gaurnier]

Thanks for the reply, I added if(!mainWindow), but it evaluates to true, so it is really a window. For arguments sake I commented out the config->init, and it didn't make a difference.

If you have code that works, could you post just that portion of the code?

[Tory Gaurnier]

I should also note that the window itself does show, and any components (such as a text area) I put in it will show as well, just not the menu bar.

In case it makes a difference I'm on Ubuntu 14.04
