Update label of tkinter menubar item?

Question

Is it possible to change the label of an item in a menu with tkinter? In the following example, I'd like to change it from "An example item" (in the "File" menu) to a different value. ``` from tkinter import * root = Tk() menu_bar = Menu(root) file_menu = Menu(menu_bar, tearoff=False) file_menu.add_command(label="An example item", command=lambda: print('clicked!')) menu_bar.add_cascade(label="File", menu=file_menu) root.config(menu=menu_bar) root.mainloop() ```

Accepted Answer

I found the solution myself in the Tcl manpages:

Use the `entryconfigure()` method like so, which changes the value after it has been clicked:

The first parameter `1` has to be the index of the item you want to change, starting from 1.

```
from tkinter import *

root = Tk()
menu_bar = Menu(root)

def clicked(menu):
    menu.entryconfigure(1, label="Clicked!")

file_menu = Menu(menu_bar, tearoff=False)
file_menu.add_command(label="An example item", command=lambda: clicked(file_menu))
menu_bar.add_cascade(label="File", menu=file_menu)

root.config(menu=menu_bar)
root.mainloop()
```
