PySimpleGUI, how to get string to print on new line instead of cutting it off?

I was working on an image viewer, but I noticed in the image viewer when the link to be displayed is too long it cuts it off. How can I modify this code So that if the string is too long, it prints it on a new line instead. I was following a guide so you can take a look at https://realpython.com/pysimplegui-python/

# img_viewer.py


import PySimpleGUI as sg

import os.path


# First the window layout in 2 columns


file_list_column = [

    [

        sg.Text("Image Folder"),

        sg.In(size=(25, 1), enable_events=True, key="-FOLDER-"),

        sg.FolderBrowse(),

    ],

    [

        sg.Listbox(

            values=[], enable_events=True, size=(40, 20), key="-FILE LIST-"

        )

    ],

]


# For now will only show the name of the file that was chosen

image_viewer_column = [

    [sg.Text("Choose an image from list on left:")],

    [sg.Text(size=(40, 1), key="-TOUT-")],

    [sg.Image(key="-IMAGE-")],

]


# ----- Full layout -----

layout = [

    [

        sg.Column(file_list_column),

        sg.VSeperator(),

        sg.Column(image_viewer_column),

    ]

]


window = sg.Window("Image Viewer", layout)


# Run the Event Loop

while True:

    event, values = window.read()

    if event == "Exit" or event == sg.WIN_CLOSED:

        break

    # Folder name was filled in, make a list of files in the folder

    if event == "-FOLDER-":

        folder = values["-FOLDER-"]

        try:

            # Get list of files in folder

            file_list = os.listdir(folder)

        except:

            file_list = []


        fnames = [

            f

            for f in file_list

            if os.path.isfile(os.path.join(folder, f))

            and f.lower().endswith((".png", ".gif"))

        ]

        window["-FILE LIST-"].update(fnames)

    elif event == "-FILE LIST-":  # A file was chosen from the listbox

        try:

            filename = os.path.join(

                values["-FOLDER-"], values["-FILE LIST-"][0]

            )

            window["-TOUT-"].update(filename)

            window["-IMAGE-"].update(filename=filename)


        except:

            pass


window.close()

To me, it's better to use library textwrap to fill your text into new text with new line '\n' before assign to sg.Text. Set size to (40, None), 40 is the wraplength.

You'll have a nice string as output, could be nicer than a list ;)

Example here:

import textwrap
import PySimpleGUI as sg

sg.theme("DarkBlue3")
sg.set_options(font=("Courier New", 16))

text = (
    "The mission of the Python Software Foundation is to promote, protect, "
    "and advance the Python programming language, and to support and "
    "facilitate the growth of a diverse and international "
    "community of Python programmers.")

new_text = textwrap.fill(text, 40)

layout = [
    [sg.Text("Line", size=(40, None), key="OUT")],
    [sg.Button("Update1"), sg.Button("Update2")],
]

window = sg.Window('Title', layout, finalize=True)

while True:
    event, values = window.read()
    if event in (sg.WINDOW_CLOSED, "Exit"):
        break
    elif event == 'Update1':
        window['OUT'].update(new_text)
    elif event == 'Update2':
        window['OUT'].update("Line")
    print(event, values)

window.close()
