Tutorial 6: Creating a Combo Element Using PySimpleGUI in Python

In this tutorial, we will be learning about how to create a Combo Element using Python PySimpleGUI. The Combo Element is used to create a dropdown menu that allows users to select from a list of options. This can be useful in various applications where user input is required.

To get started, make sure you have Python and PySimpleGUI installed on your system. You can install PySimpleGUI using pip by running the following command in your terminal:

pip install PySimpleGUI

Once you have PySimpleGUI installed, you can start creating your Combo Element using the following code:

import PySimpleGUI as sg

layout = [
    [sg.Text('Select your favorite color:')],
    [sg.Combo(['Red', 'Green', 'Blue'], default_value='Red', key='color')],
    [sg.Button('Submit')]
]

window = sg.Window('Combo Element Tutorial', layout)

while True:
    event, values = window.read()

    if event == sg.WIN_CLOSED:
        break
    elif event == 'Submit':
        selected_color = values['color']
        sg.popup(f'You have selected: {selected_color}')

window.close()

Let’s break down the code:

1. We import PySimpleGUI as sg.
2. We define our layout, which includes a Text Element prompting the user to select their favorite color, a Combo Element containing a list of color options (‘Red’, ‘Green’, ‘Blue’), and a Submit Button.
3. We create a window using the layout.
4. We enter a while loop that continuously checks for user input events.
5. If the user closes the window, we break out of the loop and close the window.
6. If the user clicks the Submit Button, we retrieve the selected color from the Combo Element and display it in a popup window.

You can customize the Combo Element by changing the list of options, setting a default value, and adding a key to access the selected value in the values dictionary. You can also add functionality to handle different events based on user input.

In conclusion, Combo Elements are a versatile way to allow users to select options from a dropdown menu in PySimpleGUI applications. They can be easily integrated into your GUI design to enhance user interaction. I hope this tutorial was helpful in guiding you through creating a Combo Element using Python PySimpleGUI.
