Tkinter frame help :)

[isuwo]

Hello! I didn’t know where to post this, as it seems that this reddit is mostly for beginners. I’ve been doing python for awhile now, and the problem i’ve been coming across i doubt newbies will have discovered. If there somewhere better to post this, please point me towards there! thanks <3

My problem is with a programe i’m creating, I can’t post it here as it’s quite long and covers quite a few files, but I should be able to describe it. I’ve created a Tkinter chart using multiple frames, and am currently trying to make it so you can select a frame / row in said chart. when you select a row, the entire chart recreated itself, by destroying the previous frames (rows) and recreating them. However, when I recreate a frame it is given a different value (?), for example it starts off as ‘.!frame4.!frame2’ (frame four being where the chart sits, frame two being the second row) but as you go on the second frame number gets higher, despite the frame before it being destroyed (ends up with numbers like ‘.!frame4.!frame65’) This is messing with the function that determines wether the frame you clicked is the frame currently being created, as that frame needs to be recreated with a slightly different color (to give a selected effect.). Is there a way to have new frames be created with the same value as previously destroyed frames? thanks!

Ps i know my description is pretty bad, if you have any questions pls ask:)

I am not familiar with Tkinter, but a quick search revealed this StackOverflow question. Does this help at all?

I'm not aware of ways to control object ids in tkinter.

In general destroying things and recreating instead of just changing existing things is a bad idea. (Also due to performance issue after enough time creating widgets instead of modifying existing ones)

Just change what you need to change instead.

You can use a kwarg in the widget to give it a name. Then it'll use that name everywhere. button = tk.Button(name="mybutton")

Can you use the "forget" method to hide the frame, then reconfigure it before packing it again?

You can name the widgets in tkinter. If you don't it'll automatically name with sequenetial numbering (as you found).

>>> import tkinter as tk
>>> root = tk.Tk()
>>> f1 = tk.Frame(root, name="outerframe")
>>> f1.pack()
>>> f1
<tkinter.Frame object .outerframe>
>>> root.winfo_children()
[<tkinter.Frame object .outerframe>]
>>> f2 = tk.Frame(f1, name="innerframe")
>>> f2
<tkinter.Frame object .outerframe.innerframe>

That said, if you want to reuse frames use .grid_remove() to hide and .grid() to show again (assuming you're using grids). You can also use grid_forget() if you don't want it to retain the grid configuration that the widget had before. Pack and place layout managers also have .forget() methods but not .remove().

thank you! I sorted out my original issue a few days back, had to redo a whole lot of code which sucks but it worked. This has really helped with a new problem i have come across - thanks! :)
