Tips for Filling Tables with Inputs using PySimpleGUI

PySimpleGUI is a powerful and easy-to-use Python library for creating graphical user interfaces. One common task when working with GUI applications is populating a table with data from user inputs. In this tutorial, we will cover how to do this using PySimpleGUI’s Table element.

1. Installation:
   Before we start, make sure you have PySimpleGUI installed. You can install PySimpleGUI using pip:

pip install PySimpleGUI

1. Import PySimpleGUI:
   Next, we need to import PySimpleGUI in our Python script:

import PySimpleGUI as sg

1. Create the GUI window:
   Let’s create a simple GUI window with two input fields for the user to enter data and a button to add the data to a table.

layout = [
    [sg.InputText(), sg.InputText(), sg.Button('Add')],
    [sg.Table(values=[], headings=['Column 1', 'Column 2'], auto_size_columns=False, col_widths=[10, 10])]
]

window = sg.Window('Table Filling', layout)

1. Create the event loop:
   Now, we need to create an event loop to handle user inputs and update the table with the entered data.

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

    if event == sg.WIN_CLOSED:
        break

    if event == 'Add':
        if values[0] and values[1]:
            # Add the data to the table
            table_data.append([values[0], values[1]])
            window['Table'].update(values=table_data)

1. Run the GUI:
   Finally, we need to run the GUI by calling the read() method on the window object.

window.close()

And that’s it! You now have a simple GUI application that allows users to enter data into input fields and populate a table with the entered data. You can expand on this example by adding functionality to edit or delete rows in the table, or by saving the table data to a file.

Overall, PySimpleGUI makes it easy to create interactive GUI applications in Python, and filling tables from user inputs is just one of the many tasks you can accomplish with this powerful library. I hope this tutorial has been helpful in getting you started with PySimpleGUI and building GUI applications in Python.
