Python GUI with PySimpleGUI – easy to learn
If you are a Python developer looking to add a graphical user interface (GUI) to your applications, PySimpleGUI is an excellent choice. PySimpleGUI is a Python library that makes it easy to create simple and powerful GUIs for your Python applications. In this article, we will explore the basics of using PySimpleGUI to create a GUI for a Python application.
Getting Started with PySimpleGUI
To get started with PySimpleGUI, you first need to install the library. You can do this using pip, the Python package manager, by running the following command in your terminal or command prompt:
“`html
“`
Once you have installed PySimpleGUI, you can start creating your GUI. PySimpleGUI uses a simple and intuitive syntax that makes it easy to create GUIs without having to write a lot of code. Here’s a basic example of a PySimpleGUI program that creates a simple window with a button:
“`html
import PySimpleGUI as sg
layout = [[sg.Text(‘Hello, world!’)], [sg.Button(‘OK’)]]
window = sg.Window(‘My first GUI’, layout)
while True:
event, values = window.read()
if event == sg.WINDOW_CLOSED or event == ‘OK’:
break
window.close()
“`
In this example, we import the PySimpleGUI library and create a layout for our GUI, which consists of a text element and a button. We then create a window with the layout and enter a loop that waits for events to occur. When the user clicks the button or closes the window, we break out of the loop and close the window.
Creating More Complex GUIs with PySimpleGUI
PySimpleGUI makes it easy to create more complex GUIs as well. You can add elements such as input fields, sliders, checkboxes, and more to your GUI, and you can also customize the appearance of your GUI using themes and styling options.
Here’s an example of a slightly more complex PySimpleGUI program that creates a GUI with an input field, a button, and a text element that displays the input from the user:
“`html
import PySimpleGUI as sg
layout = [[sg.Text(‘Enter your name:’), sg.InputText()], [sg.Button(‘OK’)], [sg.Text(size=(30, 1), key=’-OUTPUT-‘)]]
window = sg.Window(‘My second GUI’, layout)
while True:
event, values = window.read()
if event == sg.WINDOW_CLOSED or event == ‘OK’:
break
window[‘-OUTPUT-‘].update(‘Hello, ‘ + values[0])
window.close()
“`
In this example, we create a layout with an input field, a button, and a text element. When the user clicks the button, the text element is updated to display the input from the user.
Conclusion
PySimpleGUI is a powerful and easy-to-learn library for creating graphical user interfaces in Python. Whether you are a beginner or an experienced Python developer, PySimpleGUI can help you quickly and easily add a GUI to your Python applications. With its simple syntax and extensive documentation, PySimpleGUI is a great choice for anyone looking to create powerful GUIs for their Python applications.
