[SOLVED] Painting QGraphicsItem constant size

[aamer4yu]

How about using QGraphicsItem::setFlags(QGraphicsItem::ItemIgnoresTransformations)

That's PERFECT, thank you!

Ach, I take that back, it's not perfect!

After making this change, when I zoom in, the scrollbars don't appear as they did before! How do I fix this?

[Lykurg]

did you update your scene rect after zooming?

Yep, that did the trick, thanks! I thought QGraphicsView would do it for me, but I suppose that flag I set prevents that from happening.


In case anyone stumbles on this thread in the future, here's what I did: after setting the proper scale in the zoom function, I added

// Update the scene's bounds
QRectF rect = scene()->itemsBoundingRect();
if (rect.isNull())
    scene()->setSceneRect(QRectF(0, 0, 1, 1));
else
    scene()->setSceneRect(rect);

// Update the scene's bounds
QRectF rect = scene()->itemsBoundingRect();
if (rect.isNull())
    scene()->setSceneRect(QRectF(0, 0, 1, 1));
else
    scene()->setSceneRect(rect);
