Scrolling in QGraphicsView

[damian28102000]

Hi!
I would like to be able to scroll where the mouse is in QGraphicsView, something like this: https://youtu.be/4dq7n8S9AHw
Unfortunately, the solution presented on yt doesn't work in the newer version of qt (I'm using 6.0.1).

I mean scroll in two directions where the mouse is now.

Anyone have an idea how to move a solution from yt to a newer version, or is able to present a better one?

set Transformation Anchor for Your QGraphicsView
QGraphicsview::setTransformationAnchor(QGraphicsView::AnchorUnderMouse);

I am using same solution and it is working correctly.

Hi,

Please provide a minimal compilable example that shows the issue.

@damian28102000 You already asked that in Polish part of the forum and I already explained that using Qt6 is sort of pointless atm due to many parts and modules still missing. I also advised you to roll back to Qt5, where you know it works.

When I have the mouse on the red point I would like the x and y axes to get closer to exactly that point.
Now you understand me? (sorry for the response time :( )

a bit like a "magnifier" in paint but on the mouse scroll
