The code I pasted had 14 lines (including two empty ones). So how it
„actually works”, according to you?

To help you see my point of view, here's a follow-up question: and how
do you think, reading my posts — and a code snippet, you've cut out so
conveniently — what kind of „Display and Screen structure” I had in
mind? A physical device, or the one from „some case”?
