access subitem in tkinter Menu

[deanhystad]

Why not keep a handle to the menus?

from tkinter import *

class MyProgram:
    def __init__(self):
        self.tk = Tk()
        
        self.menu = Menu(self.tk)
        self.tk.config(menu=self.menu)

        self.main_menu = Menu(self.menu, tearoff=0)
        self.main_menu .add_command(label="StartScreen")
        self.main_menu .add_command(label="Settings")
        self.main_menu .add_command(label="Exit")
        self.menu.add_cascade(label="Main", menu=self.main_menu )

        self.file_menu = Menu(self.menu, tearoff=0)
        self.file_menu.add_command(label="Open")
        self.file_menu.add_command(label="Save")
        self.file_menu.add_command(label="Print")
        self.menu.add_cascade(label="File", menu=self.file_menu)

        self.test_menu = Menu(self.menu, tearoff=0)
        self.test_menu.add_command(label="Test")
        self.menu.add_cascade(label="Test", menu=self.test_menu)

demo = MyProgram()
demo.file_menu.entryconfigure("Save", state=DISABLED)

mainloop()
