Frame of fixed size staying at the bottom of the window-CodePudding

I am using Tk GUI and I want my window to be split into 2 frames, something like that:

import tkinter as tk

root = tk.Tk()
root.geometry('1000x800')

df_frame = tk.LabelFrame(root)

df_frame.place(relwidth = 1, height = 720)

open_file_frame = tk.LabelFrame(root)
open_file_frame.place(x = 0, y = 720, relwidth = 1, height = 80)

root.mainloop()

My problem is that I don't know how to make it adaptable to the size of the window. If the user enlarges the size of the window, I want the second frame to stay at the bottom, and the first frame to enlarge accordingly. Thanks in advance for your help.

CodePudding user response：

You can combine relheight and height options to control the height of the top frame.

And combine rely and y options to put the bottom frame at the bottom of the window:

import tkinter as tk

root = tk.Tk()
root.geometry('1000x800')

df_frame = tk.LabelFrame(root)
# frame_height = window_height - 80
df_frame.place(relwidth=1, relheight=1, height=-80)

open_file_frame = tk.LabelFrame(root)
# frame y position = 80 pixel from the bottom
open_file_frame.place(rely=1, y=-80, relwidth=1, height=80)

root.mainloop()
