Installing PySimpleGUI and Creating a Basic Program: Tutorial 1

PySimpleGUI is a simple yet powerful Python GUI library that allows users to quickly and easily create graphical user interfaces for their Python projects. In this tutorial, we will go over the installation process of PySimpleGUI and create a simple program to demonstrate its basic features.

Step 1: Installation

To install PySimpleGUI, you can use pip, which is the package installer for Python. Open your command prompt or terminal and run the following command:

pip install PySimpleGUI

This will download and install the PySimpleGUI library onto your system. Once the installation is complete, you can start creating GUI applications using PySimpleGUI.

Step 2: Creating a Simple Program

Now that we have PySimpleGUI installed, let’s create a simple program that displays a window with a text input field and a submit button. When the submit button is clicked, the text entered in the input field will be displayed in a popup window.

import PySimpleGUI as sg

# Define the layout of the GUI
layout = [
    [sg.Text('Enter your name:'), sg.InputText()],
    [sg.Button('Submit')]
]

# Create the window
window = sg.Window('Simple Program', layout)

# Event loop to process events and interact with the window
while True:
    event, values = window.read()

    if event == sg.WIN_CLOSED:
        break
    elif event == 'Submit':
        name = values[0]
        sg.popup(f'Hello, {name}!')

# Close the window
window.close()

In this code snippet, we first import the PySimpleGUI library using the alias sg. Next, we define the layout of the GUI using a list of lists. Each inner list represents a row of the GUI, with elements such as text labels, input fields, and buttons.

We then create the window using the sg.Window() function, passing in the title of the window and the layout we defined earlier. The sg.Window() function returns a window object that we can use to interact with the GUI.

Inside the event loop, we process events that occur in the window using the window.read() function. If the user closes the window, we break out of the loop and close the window. If the user clicks the submit button, we retrieve the text entered in the input field and display it in a popup window using the sg.popup() function.

Finally, we close the window using the window.close() function to release any resources associated with the window.

Conclusion

In this tutorial, we have covered the installation of PySimpleGUI and created a simple program to demonstrate its basic features. PySimpleGUI allows you to quickly and easily create GUI applications in Python, making it a great tool for developers of all skill levels. You can explore more advanced features of PySimpleGUI to create more complex and interactive GUI applications for your Python projects.
