Revamped Version of PySimpleGUI Popups 2.0

In PySimpleGUI 2.0, popups are a convenient way to display messages, alert users, or prompt for input in your Python GUI applications. In this tutorial, we will cover how to create and customize popups using PySimpleGUI 2.0.

1. Installing PySimpleGUI 2.0:
   Before we start, make sure that you have PySimpleGUI installed in your Python environment. You can install PySimpleGUI 2.0 using pip by running the following command:

pip install PySimpleGUI==2.0.0

1. Importing PySimpleGUI:
   To use PySimpleGUI in your Python script, you need to import the PySimpleGUI library. You can import PySimpleGUI with the following line of code:

import PySimpleGUI as sg

1. Creating Simple Popup Messages:
   PySimpleGUI provides a simple and straightforward way to display popup messages using the popup function. You can create a simple popup message like this:

sg.popup('Hello, World!')

This will display a popup with the message "Hello, World!".

1. Customizing Popup Messages:
   You can customize the appearance and behavior of the popup messages using various parameters. Here are some common parameters that you can use:

• title: The title of the popup window.
• button: The text displayed on the button.
• background_color: The background color of the popup window.
• text_color: The text color of the message.
• font: The font of the message.

Here’s an example of customizing a popup message:

sg.popup('Hello, World!', title='Custom Popup', button='OK', background_color='blue', text_color='white', font=('Helvetica', 12))

1. Prompting for Input:
   You can also create popups that prompt the user for input using the popup_get_text function. This function allows you to display a popup with an input field where the user can enter text. You can retrieve the text entered by the user and use it in your Python script. Here’s an example:

user_input = sg.popup_get_text('Enter your name:')
sg.popup(f'Hello, {user_input}!')

In this example, the user is prompted to enter their name, and their input is displayed in a popup message.

1. Handling Button Clicks:
   You can also handle button clicks in popups by using the popup_get_button function. This function displays a popup with customizable buttons and returns the text of the button that the user clicked. Here’s an example:

button = sg.popup_get_button('Click a button:', buttons=['Yes', 'No', 'Cancel'])
sg.popup(f'You clicked: {button}')

In this example, the user is presented with three buttons, and the text of the button they clicked is displayed in a popup message.
