Tutorial #06: File browsing, table creation, and more with Python PySimpleGUI

In this tutorial, we will explore how to use PySimpleGUI to create a file browse dialog, display data in a table using PySimpleGUI’s table element, as well as some additional features such as changing themes and customizing window layouts.

Step 1: Install PySimpleGUI
First, make sure you have PySimpleGUI installed on your system. You can install it using pip:

pip install PySimpleGUI

Step 2: Create a File Browse Dialog
To create a file browse dialog, we first need to import PySimpleGUI and create a layout for our window. Here’s an example code snippet to create a simple file browse dialog:

import PySimpleGUI as sg

layout = [
    [sg.InputText(), sg.FileBrowse(button_text='Browse')],
    [sg.Button('Ok'), sg.Button('Cancel')]
]

window = sg.Window('File Browse Dialog', layout)

while True:
    event, values = window.read()
    if event in (sg.WIN_CLOSED, 'Cancel'):
        break
    elif event == 'Ok':
        print('Selected File:', values[0])

window.close()

In this code snippet, we create a window with an input text field and a file browse button. When the file browse button is clicked, a file dialog will open allowing the user to select a file. The selected file path will be displayed in the input text field.

Step 3: Create a Table
Next, let’s create a table to display data. PySimpleGUI provides a table element that makes it easy to display tabular data. Here’s an example code snippet:

import PySimpleGUI as sg

data = [
    ['John', 25, 'Chicago'],
    ['Sarah', 28, 'New York'],
    ['Michael', 30, 'Los Angeles']
]

layout = [
    [sg.Table(data, headings=['Name', 'Age', 'City'])],
    [sg.Button('Ok'), sg.Button('Cancel')]
]

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

while True:
    event, values = window.read()
    if event in (sg.WIN_CLOSED, 'Cancel'):
        break

window.close()

In this code snippet, we create a table with sample data (name, age, city) and display it in a window. The table will have column headings ‘Name’, ‘Age’, and ‘City’.

Step 4: Change Theme and Customize Window Layout
PySimpleGUI allows you to easily change the theme of your GUI application. You can choose from a variety of themes provided by PySimpleGUI. Here’s how you can change the theme and customize the window layout:

import PySimpleGUI as sg

sg.theme('LightGreen')

layout = [
    [sg.Text('Enter your name:'), sg.InputText()],
    [sg.Button('Submit')]
]

window = sg.Window('Custom Theme Example', layout)

while True:
    event, values = window.read()
    if event == sg.WIN_CLOSED:
        break

window.close()

In this code snippet, we change the theme to ‘LightGreen’ and customize the layout with a text input field and a submit button.

That’s it for this tutorial on using PySimpleGUI for file browse, table display, changing themes, and customizing window layouts. I hope you found this tutorial helpful!
