Python Tkinter – Set Entry width 100%

Tkinter Entry widgets accept single-line user input in a text field. We can change the properties of the Entry widget by providing the default attributes and values in its constructor.

Let us suppose that we want to create a full-width Entry widget for an application. There are several ways to do that but if we consider the simplest case where we use Pack Geometry Manager to display the Entry widget, then we can definitely set the width of Entry widget by adding fill(x or y) property.


# Import the required library
from tkinter import *
from tkinter import ttk

# Create an instance of tkinter frame or window
win= Tk()

# Set the size of the window

# Add bottom widgets in the application
label= Label(win, text= "Enter Your Name")

# Add an entry widget
entry= Entry(win)



Executing the above code will display a full-width Entry widget which is expanded to cover the X-axis in the window.
