Qt making a qmainwindow with videowidget inside displaying an image

Question

I am writing an application using <Phonon/VideoWidget>.

I'd like to have two windows. One is the main window with controls for the video And the other has the video itself. It will be displayed in another monitor. -fullscreen or not.

How can I make the video window - that can be moved or resizabled - with the video inside?

When not playing any video, the video window should display an image.

In the end I didnt use QStackedWidget, I extended Phonon::VideoWidget and made this class...

Heres the cpp:

MyVideoWidget::MyVideoWidget(QWidget *parent) : Phonon::VideoWidget(parent)
{
    label = new QLabel(this);
    label->setAutoFillBackground(true);
    label->setBackgroundRole(QPalette::Light);
    label->setScaledContents(true);
}

void MyVideoWidget::mouseDoubleClickEvent(QMouseEvent* event)
{
    if(!this->isFullScreen())
        this->enterFullScreen();
    else
        this->setFullScreen(false);
}

void MyVideoWidget::keyPressEvent(QKeyEvent* event)
{
    if(event->key() == Qt::Key_Escape)
    {
        if(!this->isFullScreen())
            this->enterFullScreen();
        else
            this->setFullScreen(false);
    }
}

void MyVideoWidget::enterImageMode(QString imagePath)
{
    QPixmap pmap;
    pmap.fill(QColor(255, 255, 255));
    if(!pmap.load(imagePath))
    {
        label->setText("Erro ao carregar imagem: "+imagePath);
        if(!label->isVisible())
                label->show();
        return;
    }
    label->setPixmap(pmap);
    if(!label->isVisible())
        label->show();
    repaint();
}

void MyVideoWidget::enterVideoMode()
{
    label->hide();
}

void MyVideoWidget::resizeEvent(QResizeEvent* event)
{
    Phonon::VideoWidget::resizeEvent(event);
    label->setGeometry(this->geometry());
    repaint();
}

MyVideoWidget::~MyVideoWidget() 
{

}
