    Question Screenshot of QGraphicsScene with QGraphicsProxyWidget

    I have a QGraphicsScene with a few QGraphicsPixmapItems and the QGraphicsProxyWidget added to it. When the screenshot is taken the the QGraphicsProxyWidget doesn't show up in the screenshot.

    The code for the screenshot i tried unsuccessfully are the following :-
    Qt Code:
    1. QPixmap MainWindow::getScreenShot(){
    2. QPixmap screenshotPixmap = ui->graphicsView->grab();
    3. return screenshotPixmap;
    4. }
    To copy to clipboard, switch view to plain text mode 

    Qt Code:
    1. QPixmap MainWindow::getScreenShot(){
    2. QImage img(scene->sceneRect().size().toSize(), QImage::Format_ARGB32_Premultiplied);
    3. QPainter painter(&img);
    4. //scene->render(&painter);
    5. ui->graphicsView->render(&painter);
    6. QPixmap tempPixmap;
    7. tempPixmap.convertFromImage(img);
    8. return tempPixmap;
    9. }
    To copy to clipboard, switch view to plain text mode 

    What other alternative methods can be used to get the screenshot with the QGraphicsProxyWidget also present in it?

    I would expected all three methods to work more or less the same.

    So the normal graphics items show up but the proxied widgets do not?
    Which kind of widgets are those?

    Cheers,

    Hi,

    Yes the QGraphicsPixmapItems show up but the proxy widgets (Few push buttons) don't show up in the screenshot image.
