Download this code from https://codegive.com
Certainly! Below is a tutorial on creating a Python Tkinter GUI with a Listbox that updates on each button click. This tutorial assumes you have a basic understanding of Python and Tkinter.
Let's go through the code step by step:
Import Tkinter: Import the Tkinter module using import tkinter as tk.
Define the update_listbox function: This function will be called when the "Update Listbox" button is clicked. It clears the current items in the Listbox, gets the text from the Entry widget, inserts the new item into the Listbox, and clears the Entry widget for the next input.
Create the main Tkinter window: Create the main window using tk.Tk() and set its title.
Create Entry widget: Create an Entry widget (entry) for user input and pack it into the window.
Create Update Button: Create a Button widget (update_button) with the label "Update Listbox" and associate it with the update_listbox function.
Create Listbox widget: Create a Listbox widget (listbox) to display the items and pack it into the window.
Pre-fill the Listbox: Optionally, pre-fill the Listbox with some initial items.
Start the Tkinter event loop: Start the main event loop using root.mainloop().
Run this script, and you should see a simple Tkinter window with an Entry widget, a button, and a Listbox. Enter text into the Entry widget, click the "Update Listbox" button, and the entered item will be added to the Listbox.
