Menubutton Widget in Tkinter

The Menubutton widget in tkinter is used to create a menu-driven button. Unlike the regular button, when the Menubutton is clicked, it displays a dropdown menu with a list of options.

Menubutton Widget in tkinter Tutorial:

1. Import Required Libraries:

import tkinter as tk

2. Initialize Main Application Window:

root = tk.Tk()
root.title("Menubutton Widget Tutorial")

3. Creating a Basic Menubutton:

The Menubutton is typically used in conjunction with the Menu widget. Let's create a basic Menubutton with a dropdown menu:

mb = tk.Menubutton(root, text="Choose Options", relief=tk.RAISED)
mb.pack(pady=20)

menu = tk.Menu(mb, tearoff=0)
mb.config(menu=menu)

menu.add_command(label="Option 1")
menu.add_command(label="Option 2")
menu.add_command(label="Option 3")

4. Adding Submenus to the Menubutton:

You can add cascading submenus to the main menu. Here's how you can do it:

submenu = tk.Menu(menu, tearoff=0)
menu.add_cascade(label="Sub Options", menu=submenu)

submenu.add_command(label="Sub Option 1")
submenu.add_command(label="Sub Option 2")
submenu.add_command(label="Sub Option 3")

5. Adding Command Functions:

You can also add command functions that will execute when a particular option is clicked:

def on_option_click(option):
    print(f"You clicked {option}")

menu.add_command(label="Option 4", command=lambda: on_option_click("Option 4"))
submenu.add_command(label="Sub Option 4", command=lambda: on_option_click("Sub Option 4"))

6. Using Various Options with Menubutton:

The Menubutton provides several options for customization:

  • text: The text displayed on the button.
  • bg: Background color of the button.
  • fg: Foreground color (color of the text).
  • relief: Type of the border around the button. Examples include tk.FLAT, tk.RAISED, tk.SUNKEN, tk.GROOVE, and tk.RIDGE.

7. Mainloop to Run the Application:

root.mainloop()

Complete Code:

import tkinter as tk

def on_option_click(option):
    print(f"You clicked {option}")

root = tk.Tk()
root.title("Menubutton Widget Tutorial")

mb = tk.Menubutton(root, text="Choose Options", relief=tk.RAISED)
mb.pack(pady=20)

menu = tk.Menu(mb, tearoff=0)
mb.config(menu=menu)

menu.add_command(label="Option 1")
menu.add_command(label="Option 2")
menu.add_command(label="Option 3")

submenu = tk.Menu(menu, tearoff=0)
menu.add_cascade(label="Sub Options", menu=submenu)

submenu.add_command(label="Sub Option 1")
submenu.add_command(label="Sub Option 2")
submenu.add_command(label="Sub Option 3")

menu.add_command(label="Option 4", command=lambda: on_option_click("Option 4"))
submenu.add_command(label="Sub Option 4", command=lambda: on_option_click("Sub Option 4"))

root.mainloop()

# Build a menu system with Menubuttons
file_menu = tk.Menubutton(root, text="File")
file_menu.grid(row=0, column=0)
file_submenu = tk.Menu(file_menu, tearoff=False)
file_submenu.add_command(label="Open", command=lambda: option_selected("Open"))
file_submenu.add_command(label="Save", command=lambda: option_selected("Save"))
file_menu.config(menu=file_submenu)

edit_menu = tk.Menubutton(root, text="Edit")
