Enhancing GUI Flexibility with Tkinter's ttk Sizegrip Widget

Sizegrip is part of Tkinter ttk module. ( What is ttk ? )

ttk Sizegrip with style

The ttk Sizegrip widget is a small yet powerful tool in the Tkinter toolkit that allows users to resize a window by dragging the grip handle.

sizegrip = ttk.Sizegrip(my_w)
sizegrip.grid(row=2,column=1,sticky='se')

Adding Style to Sizegrip

s = ttk.Style()
s.configure('TSizegrip', background='red')

How to align Sizegrip at bottom right in Grid Layout

More details on Grid Layout here. Use rowconfigure() and columnconfigure() here.
sticky : must be a string containing n, e, s, and/or w

from tkinter import ttk
import tkinter as tk

my_w = tk.Tk()
my_w.geometry("550x240") # width and height of window 
my_w.title("www.plus2net.com") # title

my_w.rowconfigure(1,weight=1)
my_w.rowconfigure(2,weight=4)
my_w.columnconfigure(1,weight=1)

s = ttk.Style()
s.configure('TSizegrip', background='red')
font1=['Times',22,'normal'] # font family , size and style

lb1=tk.Label(my_w,text=' Sizegrip for resizing the window  ',
             height=3, bg='yellow',font=font1)
lb1.grid(row=1,column=1,padx=20,pady=20)

sizegrip = ttk.Sizegrip(my_w)
sizegrip.grid(row=2,column=1,sticky='se')

my_w.mainloop()  # Keep the window open

How to align Sizegrip at bottom right in Pack Layout

More on Pack Layout.

Check how different combination of side and anchor values can position the Sizegrip.

side: must be top, bottom, left, or right
anchor : must be n, ne, e, se, s, sw, w, nw, or center

import tkinter as tk
from tkinter import ttk

# Creating the main window
my_w = tk.Tk()
my_w.geometry('300x200')

s = ttk.Style()
s.configure('TSizegrip', background='red')
# Adding the Sizegrip widget
sizegrip = ttk.Sizegrip(my_w)
#sizegrip.pack(side='bottom',anchor='se')
#sizegrip.pack(side='right',anchor='s')
sizegrip.pack(side='left',anchor='s')

my_w.mainloop()

Preventing resizing of window

We can manage the resizable() method of parent window.

my_w.resizable(width=0,height=0) # No resize  
#my_w.resizable(width=1,height=0) # Only width resize is allowed
#my_w.resizable(width=0,height=1) # Only height resize is allowed
#my_w.resizable(width=1,height=1) # Both height and width resize is allowed ( default )

Here is complete code.

import tkinter as tk
from tkinter import ttk

# Creating the main window
my_w = tk.Tk()
my_w.geometry('300x200')

my_w.resizable(width=0,height=0) # No resize of window 
#my_w.resizable(width=1,height=0) # Only width resize is allowed
#my_w.resizable(width=0,height=1) # Only height resize is allowed
#my_w.resizable(width=1,height=1) # Both height and width resize is allowed ( default )

s = ttk.Style()
s.configure('TSizegrip', background='red')
# Adding the Sizegrip widget
sizegrip = ttk.Sizegrip(my_w)
sizegrip.pack(side='bottom',anchor='se')

my_w.mainloop()

Positioning the ttk Sizegrip widget

With the pack manager, placing the Sizegrip at the bottom right can be achieved by setting side='right' and anchor='se'

For the grid system, you might reserve the bottom right cell for the Sizegrip by adjusting its row and column index appropriately, ensuring it's the last widget added to maintain its position.

When using place, precise positioning is possible by specifying the Sizegrip's relx and rely coordinates directly, usually based on the window's width and height to anchor it at the bottom right corner.

Event Binding for ttk Sizegrip Resizing window

We will print the size ( width and height ) of the window on resizing.

from tkinter import ttk
import tkinter as tk

my_w = tk.Tk()
my_w.geometry("550x240") # width and height of window 
my_w.title("www.plus2net.com") # title

my_w.rowconfigure(1,weight=1)
my_w.rowconfigure(2,weight=4)
my_w.columnconfigure(1,weight=1)

def my_resize(event):
     lb1.config(text="Width : " + str(my_w.winfo_width())+ ", Height :" + str(my_w.winfo_height()))
     
s = ttk.Style()
s.configure('TSizegrip', background='red')

font1=['Times',16,'normal'] # font family , size and style

lb1=tk.Label(my_w,text='',height=3, bg='yellow',font=font1)
lb1.grid(row=1,column=1,padx=20,pady=20)

sizegrip = ttk.Sizegrip(my_w)
sizegrip.grid(row=2,column=1,sticky='se')

my_w.bind("<Configure>", my_resize)
my_w.mainloop()  # Keep the window open
