QGraphicsScene is not working on player widget?

R_Irudezu

I'll try explain the problem as much as i can.

First of all, i have a QGraphicsScene item with animated:

    timeline = new QTimeLine;
    timeline->setDuration (3000);
    timeline->setCurveShape (QTimeLine::CosineCurve);

    QObject::connect (timeline, SIGNAL(finished()), timeline, SLOT(deleteLater()));

    scene = new QGraphicsScene(ui->playerWidget);   
    ui->graphicsView->setScene(scene);
    ui->graphicsView->setStyleSheet("background-color: transparent; border: none;");
    ui->graphicsView->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    ui->graphicsView->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff );
    scene->setSceneRect (-60, -60, 150, 150);

    setupRot (timeline, scene->addEllipse (rect (50), QPen (QBrush (QColor (0, 153, 255)), 4, Qt::DotLine)));
    scene->addEllipse (rect (45), QPen (QBrush (QColor ("grey")), 4));
    timeline->setLoopCount (0);
    timeline->start();

this plays a circular shape with infinite loop. I want to show this on player widget, the player widget is:

    // I dragged and dropped a widget in UI named "playerWidget" 
    player = new QMediaPlayer(this);
    videoWidget = new QVideoWidget(ui->playerWidget);

The problem is (or my blindness), this graphic scene is working on a dragged and dropped widget but not working on playerWidget, i don't know why.

By the way, playerWidget is playing an RTSP stream.

Hi
Im not sure what issue really is.
However, if you mean when you drag a widget
to the playing video and widget is no longer shown, its mostly due
to the video being an overlay so it will always be in front.

@mrjj exactly this is, so this graphicsScene layer is behind the player. So is there anyway to show graphicsScene widget in front of the playerWidget?

@R_Irudezu
On windows, i think no. At least i had no success.
However, it seems you can subclass and add a paintEvent to draw what you want.

@mrjj If possible, can you show me a simple example with referencing to my first message above.
By the way. is it possible to set a new transparent widget or label over playerWidget then draw on it. I tried but didn't get success.
