Python 3 – Tkinter Menubutton

Tkinter is a powerful library in Python for creating graphical user interfaces. The Menubutton widget in Tkinter is an option menu that allows the user to select a value from a predefined set of options. It is a graphical representation of a drop-down list.

Syntax

tk.Menubutton(master, option=value, ...)

Parameters

  • master: This parameter is used to represent the parent window in which the Menubutton is to be displayed.

  • option: There are several options that can be used with the Menubutton. These include:

Option Description
activebackground This option specifies the background color of the menu when it is active.
background This option specifies the background color of the Menubutton widget.
bitmap This option specifies a bitmap that is displayed in the Menubutton widget.
default This option specifies the default value of the Menubutton widget.
direction This option specifies the direction in which the menu is opened.
disabledforeground This option specifies the foreground color of the widget when it is disabled.
font This option specifies the font used for displaying text in the Menubutton widget.
foreground This option specifies the foreground color of the Menubutton widget.
height This option specifies the height of the Menubutton widget.
highlightbackground This option specifies the color of the highlight border when the Menubutton widget does not have focus.
highlightcolor This option specifies the color of the highlight border when the Menubutton widget has focus.
highlightthickness This option specifies the thickness of the highlight border.
indicatoron This option specifies whether an indicator is displayed to the left of the selected option.
menu This option specifies the menu that is displayed when the Menubutton widget is pressed.
padx This option specifies the horizontal padding of the Menubutton widget.
pady This option specifies the vertical padding of the Menubutton widget.
relief This option specifies the border style of the Menubutton widget.
state This option specifies the state of the Menubutton widget.
takefocus This option specifies whether the Menubutton widget can be focused.
text This option specifies the text displayed in the Menubutton widget.
textvariable This option specifies a Tkinter variable used to hold the selected value.
underline This option specifies which letter of the text should be underlined.
width This option specifies the width of the Menubutton widget.

Creating a Menubutton

Creating a Menubutton in Tkinter requires two steps: creating the menu options and then creating the Menubutton widget itself.

Creating menu options

To create a set of menu options, a Menu widget is used. It is initialized using the syntax:

tk.Menu(master, option=value, ...)

The master parameter is used to specify the parent window. The option parameter can be used to set various properties of the menu. The available options are:

Option Description
activebackground This option specifies the background color of the menu option when it is active.
activeborderwidth This option specifies the width of the menu option border when it is active.
activeforeground This option specifies the foreground color of the menu option when it is active.
background This option specifies the background color of the menu option.
bitmap This option specifies a bitmap that is displayed in the menu option.
font This option specifies the font used for displaying text in the menu option.
foreground This option specifies the foreground color of the menu option.
hidemargin This option specifies whether the margins around the menu option are hidden.
image This option specifies an image that is displayed in the menu option.
label This option specifies the text displayed in the menu option.
menu This option specifies a submenu that is displayed when the menu option is selected.
state This option specifies the state of the menu option.
underline This option specifies which letter of the text should be underlined.

Once the Menu widget is created, the options can be added to it using the add_command method. The syntax is:

menu.add_command(label="Option 1", command=my_function)

The label parameter specifies the text that will be displayed in the menu option. The command parameter specifies the function that will be called when the menu option is selected.

Creating a Menubutton

After creating the menu options, a Menubutton widget can be created using the syntax:

menubutton = tk.Menubutton(root, text="Select an option", relief="raised")

The root parameter specifies the parent window. The text parameter specifies the text that will be displayed in the Menubutton widget. The relief parameter specifies the border style of the widget.

To add the menu options to the Menubutton widget, the menu property should be set using the config method:

menubutton["menu"] = menu

This sets the menu property of the Menubutton widget to the Menu widget created earlier.

The Menubutton widget can be displayed using the pack or grid methods. For example:

menubutton.pack()

Example

Let’s create a simple example that creates a Menubutton with two options: “Option 1” and “Option 2”.

import tkinter as tk

def select_option(option):
    print("Option selected:", option)

root = tk.Tk()

menu = tk.Menu(root, tearoff=0)
menu.add_command(label="Option 1", command=lambda: select_option(1))
menu.add_command(label="Option 2", command=lambda: select_option(2))

menubutton = tk.Menubutton(root, text="Select an option", relief="raised")
menubutton["menu"] = menu
menubutton.pack()

root.mainloop()

In this example, we created a function select_option that will be called when a menu option is selected. The lambda keyword is used to pass the argument 1 or 2 to the function depending on which option is selected. The tearoff option is used to prevent the menu from being detached from the Menubutton widget.

Conclusion

In summary, the Menubutton widget in Tkinter is an option menu that allows the user to select a value from a predefined set of options. It is created by creating a set of menu options using the Menu widget, and then creating a Menubutton widget with the menu property set to the Menu widget. The Menubutton widget can be displayed using the pack or grid methods. By using the Menubutton widget, you can add a drop-down list to your graphical user interface in Python.
