I have a QGrpahicsScene in my test peoject . I have added some QgrpahicsItem in it . Also I drawn a watermark text in my QGraphicsscene in drawBackground method using QPainterPath . But the problem is Initially the text are shrinked in the scene when i start to zoomIn Deeply i can able to see the text clearly .

I want the text to be in the standard width Initially (we should see it clearly ) and also when zoomIn the text width should fixed according to the zooming size . Please can any one help on it

hi
the 40000 sample uses
http://doc.qt.io/qt-5/qtwidgets-graphicsview-chip-example.html

 const qreal lod = option->levelOfDetailFromTransform(painter->worldTransform());
...
    // Draw text
    if (lod >= 2) {
        QFont font("Times", 10);
        font.setStyleStrategy(QFont::ForceOutline);
        painter->setFont(font);
        painter->save();
        painter->scale(0.1, 0.1);
        painter->drawText(170, 220, QString("Manufacturer: Chip Manufacturer"));
        painter->restore();
    }

to draw it really small
So you should play around with painter->scale to make text bigger i think.
Did u try just to alter the font size?
