[Tkinter] How to create scrollable frame

[mandiatutti]

Rewrite your example to not have the scrollable frame, just the two buttons. Can you write your program so the buttons expand to fill the window?

It does that if in the for loop i set Parent= container instead of parent = scrollable_frame. But this way I lose the ability to scroll the frames.
If you run the program you can see a frame with green border: that's the frame in the loop. Why doesn't it resize to all the scrollable frame (red background)? 😂
