@Pl45m4 said in Window cannot shrink after expanding:
In the first place, why you set the image on every resizeEvent?
This was the only way I could find to make the label's contents be resized to fit the window. The images I'm displaying are quite hi-res TIFFs, and at native resolution they can't fit on my 1080p monitor. I assume there's a better way to do this, but I couldn't find one.
Horizontally? Vertically? Or both?
Both. Here's a video of the behavior:

And here's the configuration of another window exhibiting the same behavior

This is the full form file of that window, in case that's helpful:
