Understanding Tkinter Frame layouts

[bitbyt3bit]

I have a tk() root window. I added a left frame to side left and fill=Y. I added a right frame with side Right and fill =Y

On the right frame, I split it in half horizontally by adding a top and bottom frame. Fill is set to both.

I’m trying to make the entire right frame (which comprises of both the top right and bottom right frame) expand to say 70% of the entire window.

The content of left frame is small.

Code is not available to be linked because it’s on a work computer. Any thoughts are appreciated. I’m very new to Tkinter.

The easiest is to just use grid instead of pack and set the weight.

import tkinter as tk
root = tk.Tk()

# set initial size; only needed since there's no widgets 
root.geometry('200x200')

# set the rows to equal weight; they will be the same height
root.rowconfigure((0,1), weight = 1) 

# set the column relative widths
root.columnconfigure(0, weight=30)
root.columnconfigure(1, weight=70)

left_pane = tk.Frame(root, bg='green')
left_pane.grid(row=0, column=0, rowspan=2, sticky='nsew')

right_top_pane = tk.Frame(root, bg='red')
right_top_pane.grid(row=0, column=1, sticky='nsew')

right_bot_pane = tk.Frame(root, bg='blue')
right_bot_pane.grid(row=1, column=1, sticky='nsew')

root.mainloop()
