Why doesn't the up/down slider bar work? Python Tkinter
Question
the slider does not work, it draws it, but the command does not work. I tried all the methods on the Internet, and they do not work. I can't understand the very essence of the problem, tk. tkinter itself does not throw errors, and neither does Python itself. I read the documentation and didn't see anything useful.

Consider this block of code:
for i in __all__block:
listbox.insert('end', i.pack())
It is calling pack() on every widget created in the prior block of code. pack() returns None , so you are inserting None inside the listbox over and over and over. Inserting None results in nothing getting added to the listbox.
The listbox can only scroll text items added with the insert method. It won't scroll widgets added using pack , place , or grid .
