Creating GUIs with PySimpleGUI: Text and Display Creation

PySimpleGUI is a Python GUI library that allows you to quickly and easily create graphical user interfaces for your Python applications. In this tutorial, I will show you how to create a simple GUI with PySimpleGUI that displays text.

Step 1: Install PySimpleGUI
First, you need to install PySimpleGUI. You can do this by running the following command in your terminal:

pip install pysimplegui

Step 2: Import PySimpleGUI
Next, you need to import the PySimpleGUI library in your Python script. You can do this by adding the following line of code at the top of your script:

import PySimpleGUI as sg

Step 3: Create the GUI layout
Now, you need to create the layout for your GUI. In this example, we will create a simple GUI that displays a text message. Here is the code for the layout:

layout = [
    [sg.Text("Hello, World!")],
    [sg.Button("OK")]
]

This layout consists of a text element that displays the message "Hello, World!" and a button with the label "OK".

Step 4: Create the window
Next, you need to create the PySimpleGUI window object using the layout you created in the previous step. You can do this by adding the following code to your script:

window = sg.Window("Simple GUI", layout)

This code creates a window with the title "Simple GUI" and the layout you defined earlier.

Step 5: Display the GUI
Finally, you need to display the GUI window that you created. You can do this by adding the following code to your script:

event, values = window.read()

This code will display the GUI window and wait for the user to interact with it. Once the user interacts with the window, the event variable will contain the event that was triggered (e.g., clicking the "OK" button) and the values variable will contain the values of any input elements in the window.

Step 6: Respond to user input
Once the user interacts with the GUI window, you can respond to their input by checking the event variable. For example, if the user clicks the "OK" button, you can display a confirmation message. Here is an example of how you can respond to user input:

if event == "OK":
    sg.popup("You clicked the OK button!")

This code will display a popup message that says "You clicked the OK button!" if the user clicks the "OK" button in the GUI window.

Step 7: Close the window
Finally, you need to close the GUI window once the user is done interacting with it. You can do this by adding the following code to your script:

window.close()

This code will close the GUI window and clean up any resources used by PySimpleGUI.

That’s it! You have now created a simple GUI with PySimpleGUI that displays text. You can customize the layout and functionality of your GUI by adding more elements and event handlers. Happy coding!
