Adjustable QGraphicsView?

[jiapei100]

I'd love to realize something like:

when loading an image, no matter what size it is, I'm able to load it into a QGraphicsView, which is not of a fixed size.
Namely, I hope in my QMainWindow or QFrame or QDialog, this QGraphicsView is not of a fixed size, but a flexible and adjustable size, which will automatically adjust its size due to the loading image size.

Is it possible to realize this?

Best Regards
JIA

No matter how large you make the graphics view, if the image size is larger it wont fit in it.
You can have a look at QGraphicsView::fitInView if it suits you
