    Default [QT4.1.1 XP] background image

    I try to set the background of a widget to an image as indicated in Assistant in the
    Porting to QT4 of setPaletteBackgroundPixmap :
    Qt Code:
    1. QWidget *widget = new QWidget;
    2. QPixmap pixmap(":/images/bArchi.png");
    3. QPalette palette;
    4. palette.setBrush(widget->backgroundRole(), QBrush(pixmap));
    5. widget->setPalette(palette);
    6. setCentralWidget(widget);
    To copy to clipboard, switch view to plain text mode 

    I played around with many combinations of the above code, but nothing will show my
    image. The background remains unchanged...

    Is the path to the resource image correct? Try using a file path (preferrably non-relative one) first.

    Qt Code:
    1. QPixmap pixmap("C:/Qt/test/chart/images/bArchi.png");
    To copy to clipboard, switch view to plain text mode 

    Unfortunately the absolute path has the same negative result.

    correct answer was simple but took me a while to find it :
    to change this window's background :

    Qt Code:
    1. QPalette palette;
    2. QPixmap pixmap = QPixmap("./images/bBackground.png");
    3. palette.setBrush((this)->backgroundRole(), QBrush(pixmap));
    4. (this)->setPalette(palette);
    To copy to clipboard, switch view to plain text mode
