Python Tkinter Menubutton
When creating graphical user interfaces with Python, Tkinter provides several widgets for building interactive applications. The Menubutton widget is designed to work with a menu and provides users with a convenient way to access a list of available choices.
A Menubutton can be connected to a Menu widget that contains different items. When the user interacts with the Menubutton, the associated menu provides the available selections. This makes Menubutton useful for creating navigation controls, language selectors, settings menus, and other dropdown-style interfaces.
In this tutorial, we will learn the syntax of the Tkinter Menubutton, explore its important configuration options, and understand how to create a simple Menubutton application using Python.

Syntax
The basic syntax for creating a Menubutton widget in Tkinter is:
w = Menubutton(parent, options)Here, parent represents the root window or frame where the Menubutton will be placed. The options are configuration properties that can be used to control the widget’s appearance, position, menu behavior, and other characteristics.

Example: Implementing a Tkinter Menubutton
The following example demonstrates how to create a Menubutton and connect it with a Menu widget. The menu contains two checkbutton choices: Hindi and English.
from tkinter import *
# Create main window
top = Tk()
top.geometry("200x250")
# Create Menubutton
menubutton = Menubutton(top, text="Select Language", relief=FLAT)
menubutton.grid()
# Create menu
menubutton.menu = Menu(menubutton, tearoff=0)
menubutton["menu"] = menubutton.menu
# Add checkbutton menu items
menubutton.menu.add_checkbutton(label="Hindi", variable=IntVar())
menubutton.menu.add_checkbutton(label="English", variable=IntVar())
# Display Menubutton
menubutton.pack()
top.mainloop()Output
When the program runs, a Tkinter window is displayed with a Menubutton labeled Select Language. Clicking the Menubutton opens its associated dropdown menu containing the Hindi and English choices.
The example demonstrates how a Menu can be connected to a Menubutton through the menu option. The add_checkbutton() method is then used to add selectable items to that menu.
