PySimpleGUI 2020: Part 9 – Exploring Containers and Nested Layouts in the Experimental Faster Version

In this part of the PySimpleGUI tutorial, we will be focusing on using containers to create layouts within layouts. This feature is experimental and is a faster version of creating nested layouts within PySimpleGUI.

Containers allow you to organize your GUI elements in a more structured way, making it easier to manage complex layouts. With containers, you can group elements together and manipulate them as a single entity.

To get started, make sure you have the latest version of PySimpleGUI installed on your system. You can install PySimpleGUI using pip:

pip install PySimpleGUI

Now, let’s dive into creating layouts within layouts using containers.

1. Import the necessary modules:

import PySimpleGUI as sg

1. Create a layout with a main window:

layout = [
    [ sg.Text('Main Window') ],
]

1. Create a main window using the layout:

window = sg.Window('Main Window', layout)

1. Define a function to create a nested layout within a container:

def create_nested_layout():
    nested_layout = [
        [ sg.Text('Nested Layout') ],
        [ sg.Button('Nested Button') ],
    ]
    return nested_layout

1. Create a container and add the nested layout to it:

container = sg.Container(create_nested_layout())

1. Add the container to the main window layout:

layout.append([container])

1. Update the main window layout and refresh the window:

window.update(layout)

1. Run an event loop to handle user input:

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

By following these steps, you can easily create layouts within layouts using containers in PySimpleGUI. This experimental faster version allows you to organize your GUI elements more efficiently and improve the performance of your GUI applications.

Experiment with different layouts and containers to create complex and visually appealing GUIs for your Python applications. Don’t forget to check the PySimpleGUI documentation for more information on containers and nested layouts.
