How to dynamically change text of Checkbutton in tkinter

The Checkbutton widget in tkinter can be utilized to represent options for users to select. Sometimes, you might want to dynamically change the text of a Checkbutton based on certain conditions or user actions.

Here's a tutorial on how to dynamically change the text of a Checkbutton in tkinter:

Tutorial: Dynamically Change Text of Checkbutton in Tkinter

1. Import Required Libraries:

import tkinter as tk

2. Create the Main Application Window:

root = tk.Tk()
root.title("Dynamic Checkbutton Text")

3. Function to Change Checkbutton Text:

Create a function that will change the text of the Checkbutton when invoked.

def toggle_text():
    current_text = check_var.get()
    if current_text == "Option A":
        check_var.set("Option B")
    else:
        check_var.set("Option A")

4. Create the Checkbutton with Dynamic Text:

We'll use a StringVar to manage the text of the Checkbutton. Whenever the value of this StringVar changes, the displayed text of the Checkbutton will change as well.

check_var = tk.StringVar()
check_var.set("Option A")

check_btn = tk.Checkbutton(root, textvariable=check_var)
check_btn.pack(pady=20)

5. Create a Button to Trigger Text Change:

We'll add a Button that, when clicked, will call our toggle_text function to change the text of the Checkbutton.

toggle_btn = tk.Button(root, text="Toggle Checkbutton Text", command=toggle_text)
toggle_btn.pack(pady=20)

6. Run the Main Loop:

root.mainloop()

Complete Code:

Combine the above snippets to get the complete working program:

import tkinter as tk

def toggle_text():
    current_text = check_var.get()
    if current_text == "Option A":
        check_var.set("Option B")
    else:
        check_var.set("Option A")

root = tk.Tk()
root.title("Dynamic Checkbutton Text")

check_var = tk.StringVar()
check_var.set("Option A")

check_btn = tk.Checkbutton(root, textvariable=check_var)
check_btn.pack(pady=20)

toggle_btn = tk.Button(root, text="Toggle Checkbutton Text", command=toggle_text)
toggle_btn.pack(pady=20)

root.mainloop()

This code will display a window with a Checkbutton and a Button. When you click on the Button, the text of the Checkbutton will toggle between "Option A" and "Option B".
