Listbox Widget in Python Tkinter for Python GUI Programming

Python GUI Programming with Listbox in Python Tkinter | Listbox Widget in Python

In this tutorial, we will learn how to use the Listbox widget in Python Tkinter to create a graphical user interface (GUI) with a list of items that the user can select from.

The Listbox widget is used to display a list of items that can be scrolled and selected by the user. It is commonly used in GUI applications to provide a way for the user to select multiple items from a list.

To get started, make sure you have Python installed on your computer and that you have the Tkinter library installed. You can install Tkinter using the following command:

pip install tk

Now, let’s create a new Python file and import the necessary libraries:

import tkinter as tk
from tkinter import ttk

Next, let’s create a new Tkinter window and add a Listbox widget to it:

root = tk.Tk()

listbox = tk.Listbox(root)
listbox.pack()

# Add items to the listbox
listbox.insert(1, 'Item 1')
listbox.insert(2, 'Item 2')
listbox.insert(3, 'Item 3')

root.mainloop()

In the code above, we first create a new Tkinter window using the Tk() method. We then create a new Listbox widget and add it to the window using the pack() method.

Next, we add items to the Listbox using the insert() method. The first argument to the insert() method is the index at which to insert the item, and the second argument is the text of the item.

Finally, we start the Tkinter event loop using the mainloop() method, which will keep the window open and responsive to user input.

You can also add event handlers to the Listbox widget to respond to user interactions. For example, you can add a Double-Button-1 event handler to the listbox that will print the selected item when the user double-clicks on it:

def on_double_click(event):
    index = listbox.curselection()
    item = listbox.get(index)
    print('You selected:', item)

listbox.bind('<Double-Button-1>', on_double_click)

In the code above, we create a new event handler on_double_click() that retrieves the index of the selected item using the curselection() method and then gets the text of the selected item using the get() method. We then print the selected item to the console.

Finally, we bind the event handler to the <Double-Button-1> event using the bind() method.

And that’s it! You have now created a simple GUI application with a Listbox widget in Python Tkinter. You can further customize the appearance and behavior of the Listbox widget by exploring the various methods and options available in the Tkinter library.
