QSplashScreen on Qt Quick 2

I'm having trouble using QSplashScreen on a new Qt Quick 2 project. Here's the project 'main.cpp':

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);

    QPixmap pix("./test80.png");

    QSplashScreen splash(pix);

    splash.show();

    QTest::qSleep(5000);

    splash.hide();

    QtQuick2ApplicationViewer viewer;
    viewer.setMainQmlFile(QStringLiteral("qml/teste/main.qml"));
    viewer.showExpanded();

    return app.exec();
}

This code compiles. When I run it, application output shows the following message: QWidget: Cannot create a QWidget without QApplication. So apparently QGuiApplication doesn't inherit from QApplication, so I'm stumped.

Edit: changing QGuiApplication to QApplication seemed to work, but I'm worried that QApplication will lack something needed by Qt Quick 2.

In fact it's the other way around: QApplication inherits from QGuiApplication. And you need the former to use widgets. :-)
