How to disable word-wrap in PySimpleGUI output

wordwrap_example.py

import PySimpleGUI as sg

# create output element
output = sg.Output(size=(50, 15))

# button to initiate text printing
button = sg.Button('Print long text', key='-BTN-')

# set the layout
layout = [[output], [button]]

# create and finalize window
window = sg.Window('Output Testing', layout, finalize=True)

# turn off the word wrap (options include 'none', 'char', 'word')
output._TKOut.output.configure(wrap='none')


# run event loop
while True:
    event, values = window.read()
    if event is None:
        break
    elif event == '-BTN-':
        text = help(button)
        print(text)

window.close()

Lately I've been suggesting users switch over to the Multiline Element rather than the Output element. The reason is that there are many more options on the Multiline versus the Output element.

There is an option to re-route stdout in the Multiline Element now so your layout code is minimally impacted to make the switch. Simply set reroute_stdout=True when specifying the Multiline in the layout.

You should be able to use the same trick to disable wrapping with this line of code when using a Multiline Element.

window['MULTILINE KEY'].Widget.configure(wrap='none')
