minsize() method in Tkinter | Python

In Tkinter, minsize() method is used to set the minimum size of the Tkinter window. Using this method user can set window’s initialized size to its minimum size, and still be able to maximize and scale the window larger. 

Syntax:

master.minsize(width, height)

Here, height and width are in pixels. 

Code #1: Root window without minimum size that means you can shrink window as much you want. 

Python3




# importing only  those functions
# which are needed
from tkinter import *
from tkinter.ttk import *
from time import strftime
 
# creating tkinter window
root = Tk()
 
# Adding widgets to the root window
Label(root, text = 'Lazyroar',
      font =('Verdana', 15)).pack(side = TOP, pady = 10)
 
Button(root, text = 'Click Me !').pack(side = TOP)
 
mainloop()


Output: Initial root window without alteration in size

Root window after shrunken down, see the window is completely shrunken because it has no minimum geometry

Code #2: Root window with minimum size. 

Python3




# importing only  those functions
# which are needed
from tkinter import *
from tkinter.ttk import *
from time import strftime
 
# creating tkinter window
root = Tk()
 
# setting the minimum size of the root window
root.minsize(150, 100)
 
# Adding widgets to the root window
Label(root, text = 'Lazyroar',
      font =('Verdana', 15)).pack(side = TOP, pady = 10)
Button(root, text = 'Click Me !').pack(side = TOP)
 
mainloop()


Output: Initial window

 Initial window 

Expanded window (we can expand window as much as we want because we haven’t set the maximum size of the window). 

Expanded window 

Window shrunken to it’s minimum size (one cannot shrunk it any further).
