Tkinter scaling windows conten to or with its size not working

[Larz60+]

I wrote a tutorial on this (a long time ago) it's here: https://python-forum.io/Thread-Tkinter-G...first-time
It's been a long time since I looked at it, so perhaps I would do it differently now.
If you find it isn't applicable, please let me know and I'll review and update as needed.

Also , please post your code (in code tags)
