How to set the min and max height or width of a Frame

Question

The size of Tkinter windows can be controlled via the following methods    minsize    maxsize    resizable     Are there equivalent ways to control the size of Tkinter or ttk Frames    Bryan  I changed your frame1 pack code to the following   frame1 pack fill  both   expand True  frame1 bind    lt Configure gt    maxsize     And I added this event handler     attempt to prevent frame from growing past a certain size def maxsize  event None        print frame1 winfo width       if frame1 winfo width    gt  200          print  frame1 wider than 200 pixels          frame1 pack propagate 0          frame1 config  width 200           return  break    The above event handler detects that a frame s width is too big  but is unable to prevent the increase in size from happening  Is this a limitation of Tkinter or have I misunderstood your explanation

There is no single magic function to force a frame to a minimum or fixed size. However, you can certainly force the size of a frame by giving the frame a width and height. You then have to do potentially two more things: when you put this window in a container you need to make sure the geometry manager doesn't shrink or expand the window. Two, if the frame is a container for other widget, turn grid or pack propagation off so that the frame doesn't shrink or expand to fit its own contents.

Note, however, that this won't prevent you from resizing a window to be smaller than an internal frame. In that case the frame will just be clipped.

import Tkinter as tk

root = tk.Tk()
frame1 = tk.Frame(root, width=100, height=100, background="bisque")
frame2 = tk.Frame(root, width=50, height = 50, background="#b22222")

frame1.pack(fill=None, expand=False)
frame2.place(relx=.5, rely=.5, anchor="c")

root.mainloop()

A workaround - at least for the minimum size  You can use grid to manage the frames contained in root and make them follow the grid size by setting sticky  nsew   Then you can use root grid rowconfigure and root grid columnconfigure to set values for minsize like so   from tkinter import Frame  Tk  class MyApp        def   init   self           self root   Tk            self my frame red   Frame self root  bg  red           self my frame red grid row 0  column 0  sticky  nsew            self my frame blue   Frame self root  bg  blue           self my frame blue grid row 0  column 1  sticky  nsew            self root grid rowconfigure 0  minsize 200  weight 1          self root grid columnconfigure 0  minsize 200  weight 1          self root grid columnconfigure 1  weight 1           self root mainloop    if   name         main         app   MyApp     But as Brian wrote  in 2010  D  you can still resize the window to be smaller than the frame if you don t limit its minsize
