This repository provides a functional, pre-license version of the **PySimpleGUI** library for developers who need a free and unrestricted solution. The official PySimpleGUI library has recently transitioned to a paid license model, leaving many developers unable to access or use the library. This backup allows you to continue using the legacy version without any license requirements.

What is PySimpleGUI?

PySimpleGUI is a Python library that simplifies the process of creating graphical user interfaces (GUIs). It abstracts away the complexity of underlying frameworks like Tkinter, Qt, WxPython, and Remi, offering a beginner-friendly, high-level API. With PySimpleGUI, you can build interactive desktop applications, file explorers, progress trackers, and more with minimal code.

Key Features of PySimpleGUI:

• Beginner-Friendly: Intuitive syntax, ideal for developers new to GUIs.
• Rich Component Library: Buttons, text inputs, sliders, progress bars, tables, and more.
• Cross-Platform: Runs seamlessly on Windows, macOS, and Linux.
• Dynamic Updates: Allows real-time updates to GUI elements during execution.
• Integration Ready: Supports Matplotlib, OpenCV, and other libraries for advanced functionality.

What is PySimpleGUI Used For?

PySimpleGUI is widely used in:

• Educational Projects: Helping beginners learn GUI development.
• Data Visualization: Embedding interactive charts and graphs.
• Automation Tools: Creating simple automation utilities with user interfaces.
• Prototyping: Quickly designing and testing application interfaces.
• Lightweight Desktop Apps: Developing small-scale tools with a minimal footprint.

Why Use an Older Version of PySimpleGUI?

On [specific date of license change], the creator of PySimpleGUI announced a transition to a paid license model. As part of this change:

1. A license key is now required to use any version installed via pip.
2. Older, free versions of PySimpleGUI have been removed from the PyPI repository, preventing developers from simply downgrading to a previous version.
3. Developers who rely on PySimpleGUI for personal projects, open-source software, or educational purposes are now locked out unless they pay for a license.

This repository offers a solution by providing a backup of the last free and functional version of PySimpleGUI.

Why Can't You Use pip to Downgrade PySimpleGUI?

Normally, developers can install a specific version of a library using pip install PySimpleGUI==<version>. However, with the recent changes:

1. The author has removed older versions from the PyPI repository, making downgrading impossible.
2. This forces developers to use the latest version, which now requires a paid license.

As a result, the only way to access a fully functional version is through a saved copy, such as the one provided in this repository.

How to Use This Repository

1. Download the Legacy Version

• Download the PySimpleGUI.7z file from the Releases section.

2. Extract the Files

• Extract the PySimpleGUI.7z archive using any file extraction tool that supports the .7z format.

3. Locate Your Python site-packages Directory

• Windows Example:

  C:\Users\Administrator\AppData\Local\Programs\Python\Python310\Lib\site-packages
  

• macOS/Linux Example:

  /usr/local/lib/python3.10/site-packages
  

  (The exact path may vary depending on your Python installation.)

4. Remove Existing PySimpleGUI Installations

Before installing the legacy version, you need to remove any existing PySimpleGUI installations to prevent conflicts.

1. Navigate to your site-packages directory.

2. Delete the following folders if they exist:

   • PySimpleGUI
   • PySimpleGUI-<version>.dist-info

   Example on Windows:

   C:\Users\Administrator\AppData\Local\Programs\Python\Python310\Lib\site-packages\PySimpleGUI
   C:\Users\Administrator\AppData\Local\Programs\Python\Python310\Lib\site-packages\PySimpleGUI-4.60.1.dist-info
   

5. Install the Legacy PySimpleGUI

1. Copy the extracted PySimpleGUI folder and PySimpleGUI-<version>.dist-info folder from the .7z archive.

2. Paste these folders into your Python site-packages directory.

   Example on Windows:

   C:\Users\Administrator\AppData\Local\Programs\Python\Python310\Lib\site-packages\PySimpleGUI
   C:\Users\Administrator\AppData\Local\Programs\Python\Python310\Lib\site-packages\PySimpleGUI-4.60.1.dist-info
   

6. Verify the Installation

You can verify that the legacy version is installed correctly by running a simple PySimpleGUI script:

import PySimpleGUI as sg

# Define the layout
layout = [
    [sg.Text("Enter your name:")],
    [sg.Input(key='-INPUT-')],
    [sg.Button("Submit"), sg.Button("Exit")]
]

# Create the window
window = sg.Window("PySimpleGUI Legacy Example", layout)

# Event loop
while True:
    event, values = window.read()
    if event == sg.WINDOW_CLOSED or event == "Exit":
        break
    if event == "Submit":
        sg.popup(f"Hello, {values['-INPUT-']}!")

# Close the window
window.close()

Run the script to ensure that the GUI appears and functions as expected.
