How to Get Value Entered in Text Widget in Tkinter Python

Get Value Entered in Text Widget in Tkinter Python

In Tkinter, the Text widget is used to accept multi-line user input. To retrieve the value entered in the Text widget, the get() method is used with a specific range of indices.

The syntax to retrieve text is:

text_widget.get("start_index", "end_index")

where:

• start_index is the starting position (e.g., "1.0" for the first character of the first line).
• end_index is the ending position (e.g., "end" to retrieve all text).

In this tutorial, we will explore different ways to retrieve the value entered in the Tkinter Text widget with detailed examples.

Examples

1. Getting Text from Text Widget on Button Click

In this example, we will create a simple Tkinter application where the user enters text in a Text widget, and when they click the button, the entered text is displayed in the console.

main.py

import tkinter as tk

# Create the main window
root = tk.Tk()
root.title("Text Widget Example - tutorialkart.com")
root.geometry("400x200")

# Function to get text from Text widget
def get_text():
    entered_text = text_box.get("1.0", "end-1c")  # Exclude the trailing newline
    print("Entered Text:", entered_text)

# Create a Text widget
text_box = tk.Text(root, height=5, width=40)
text_box.pack(pady=10)

# Create a button to fetch text
btn_get = tk.Button(root, text="Get Text", command=get_text)
btn_get.pack(pady=5)

root.mainloop()

Output in Windows:

A window appears with a multi-line text box and a button labeled “Get Text”.

Enter some text into the Text box.

When the button is clicked, the text entered in the Text widget is printed in the console.

2. Displaying Entered Text in a Label

In this example, we will retrieve the text from the Text widget and display it inside a Label widget instead of printing it in the console.

main.py

import tkinter as tk

# Create the main window
root = tk.Tk()
root.title("Display Text Example - tutorialkart.com")
root.geometry("400x200")

# Function to get text and display in label
def display_text():
    entered_text = text_box.get("1.0", "end-1c")  # Remove trailing newline
    label_output.config(text="You Entered: " + entered_text)

# Create a Text widget
text_box = tk.Text(root, height=5, width=40)
text_box.pack(pady=10)

# Create a button to fetch text
btn_display = tk.Button(root, text="Show Text", command=display_text)
btn_display.pack(pady=5)

# Create a Label to display entered text
label_output = tk.Label(root, text="", fg="blue")
label_output.pack(pady=5)

root.mainloop()

Output in Windows:

A window appears with a multi-line text box, a button labeled “Show Text”, and an empty label.

When the button is clicked, the entered text is displayed inside the label.

Conclusion

In this tutorial, we explored how to retrieve values entered in a Tkinter Text widget using the get() method. We covered two examples:

• Printing the entered text in the console.
• Displaying the entered text inside a Label widget.
