How to make flexible widget from changing the window size?

I want to make my scrolledtext to change it's size with the window size

# import GUI
import tkinter as tk
from tkinter import ttk
from tkinter import scrolledtext


# create instance
win = tk.Tk()

# title name
win.title("Notepad ver.1.0")

# resizable option
win.resizable(True, True)

# geometry
win.geometry("1900x1000")

# frame 1
frame1 = ttk.LabelFrame(win, text='')
frame1.grid(column=0, row=0)
# some lables are inside frame1
ttk.Label(frame1, text='Hello World').grid(column=0, row=0)


# frame2
frame2 = ttk.LabelFrame(win, text='')
# set the width and height of your frame as desired using ipadx and ipady
frame2.grid(column=0, row=7, sticky=tk.S, ipadx=880, ipady=370)
# disable grid propagation to prevent resizing on font size changes
frame2.grid_propagate(False)

# scrolled text
ScrWidth = 0
ScrHight = 0
scr = scrolledtext.ScrolledText(frame2, wrap=tk.WORD, width=ScrWidth, height=ScrHight)
scr.pack(side='left', fill="both", expand=True, ipadx=0, ipady=0)
scr.config(font='Arial, 10')
scr.grid_propagate(False)

# start GUI
win.mainloop()

I tried to ask ChatGpt to do it and also google it and found that

win.bind("<Configure>", function)

will make my code work but it made my code more glitchy.

Thank You for everyone for helping me!

If you want the instance of ScrolledText (scr) to be resized whenever the window is resized, you need to:

  • configure its parent frame2 to use all the available space by setting sticky="nsew" in frame2.grid(...)
  • allocate all available space to row 7 and column 0 where frame2 is put by calling win.rowconfigure(7, weight=1) and win.columnconfigure(0, weight=1)

Below is the updated code:

# import GUI
import tkinter as tk
from tkinter import ttk
from tkinter import scrolledtext


# create instance
win = tk.Tk()

# title name
win.title("Notepad ver.1.0")

# resizable option
win.resizable(True, True)

# geometry
win.geometry("1900x1000")

# frame 1
frame1 = ttk.LabelFrame(win, text='')
frame1.grid(column=0, row=0)
# some lables are inside frame1
ttk.Label(frame1, text='Hello World').grid(column=0, row=0)

win.rowconfigure(7, weight=1)
win.columnconfigure(0, weight=1)

# frame2
frame2 = ttk.LabelFrame(win, text='')
# set the width and height of your frame as desired using ipadx and ipady
### changed sticky option to "nsew"
frame2.grid(column=0, row=7, sticky="nsew", ipadx=880, ipady=370)
# disable grid propagation to prevent resizing on font size changes
#frame2.grid_propagate(False)  # it is not necessary

# scrolled text
ScrWidth = 0
ScrHight = 0
scr = scrolledtext.ScrolledText(frame2, wrap=tk.WORD, width=ScrWidth, height=ScrHight)
scr.pack(side='left', fill="both", expand=True, ipadx=0, ipady=0)
scr.config(font='Arial, 10')
#scr.grid_propagate(False)  # it is not necessary

# start GUI
win.mainloop()
