I made a program to get a value from user and display data in a table equal to the user input, my problem is the data is not updated in the columns and not displayed whatever the data is retrieved and printed, I searched on it and I get nothing

I’m having a treeview element in a frame to the left, which shares the space with another element to the right, in this test case here it’s a button. When the window is resized to a smaller size, the treeview does not shrink, but the button does. The treeview only starts shrinking, when the button isn’t visible any more. It seems that the columns have something like a fixed minimum size.

I’m building a GUI with tkinter and was wondering if there is way to set a background color for rows that meet a certain criteria.

I have two questions on the python code at the bottom:

i develop on app with python and tkinter for ui. Here i got a list of object : Note with a title, date, subject, topic and content. I used a treeview to display the title, date, subject, topic, and i add the text in a child so when i click my note it expand to display the content.
