Update: So I figured out how to constrain the image when zoomed. I had to put it within a canvas and learned the word “clipping.” So I used clipping via the documentation to keep it within that box when zooming in.
I still don’t know how to “move” the widget. The obvious choice would be draganddrop operation, but I don’t want to destroy/create a new copy of the widget if that makes sense. If it doesn’t make sense, maybe I don’t quite understand how drag and drop works. I just want to “pan” like in the blueprint editor.
