Python Tkinter Entry

The Entry widget in Tkinter is used to accept single-line text input from the user. It is commonly used for login forms, data entry fields, and text input in GUI applications.

The Entry widget supports various options for customizing appearance, retrieving user input, and handling events.

In this tutorial, we will explore how to use the Tkinter Entry widget with multiple examples.

Copy

tk.Entry(master, **options)

Parameters

Parameter	Type	Description
`master`	Widget	The parent widget, usually a frame or root window.
`textvariable`	StringVar	Used to store and retrieve text from the Entry widget.
`width`	Integer	Defines the width of the Entry field (in characters).
`show`	String	Masks input text (e.g., `show="*"` for passwords).
`state`	String	Defines the state of the Entry field (`normal`, `disabled`, `readonly`).

Examples

1. Basic Entry Widget

In this example, we create a basic Entry widget where users can type text.

</>

Copy

import tkinter as tk

root = tk.Tk()
root.title("Tkinter Entry Example - tutorialkart.com")
root.geometry("400x200")

# Create an Entry widget
entry = tk.Entry(root, width=30)
entry.pack(pady=10)

root.mainloop()

Output in Windows:

A simple input field appears where users can type text.

Click on the entry widget, and a cursor appear. You may start typing some text into the entry field.

2. Retrieving User Input

This example demonstrates how to retrieve text from an Entry widget using a button click.

Copy

import tkinter as tk

root = tk.Tk()
root.title("Retrieve Entry Text - tutorialkart.com")
root.geometry("400x200")

def show_text():
    print("Entered Text:", entry.get())

# Create an Entry widget
entry = tk.Entry(root, width=30)
entry.pack(pady=10)

# Create a button to retrieve text
btn = tk.Button(root, text="Get Text", command=show_text)
btn.pack()

root.mainloop()

Output in Windows:

A text field appears with a button.

3. Password Entry Field

In this example, we will learn how to use the show option to mask user input (useful for passwords).

</>

Copy

import tkinter as tk

root = tk.Tk()
root.title("Password Entry - tutorialkart.com")
root.geometry("400x200")

# Create an Entry widget with masked input
entry = tk.Entry(root, width=30, show="*")
entry.pack(pady=10)

root.mainloop()

Output in Windows:

A password input field appears where typed characters are hidden.

4. Read-Only Entry Field

In this example, we will learn how to use the state option to make an Entry field read-only.

</>

Copy

import tkinter as tk

root = tk.Tk()
root.title("Read-Only Entry - tutorialkart.com")
root.geometry("400x200")

# Create a read-only Entry widget
entry = tk.Entry(root, width=30, state="readonly")
entry.pack(pady=10)

root.mainloop()

Output in Windows:

An entry field is displayed but users cannot type in it.
