Append text to textbox in pysimplegui?

So I'm trying to get the GUI up and running for a simple program that will check a modbus network. Which needs a giant text field to display data. I am using sg.Text. The problem I have is the text box doesn't append when updating. I am sure I am missing something obvious. I need to append because of how the program will check the network and then maybe save the entire text box. How do I make is scrollable as well? I feel like I having a massive brain fart.


import PySimpleGUI as sg
import os.path

# First the window layout in 2 columns

file_list_column = [
    [
        sg.Text("Search Network?"),
        sg.Button('Read Serial'),
        sg.Button('Test Modbus'),
    ],
    [
        sg.Text("Textbox test.", size=(30, 5),  relief=sg.RELIEF_SUNKEN, background_color='white', text_color='black',
            enable_events=True, key="-NETWORK LIST-")

    ],
    [
        sg.Input(key='-IN-')
    ],
    [
        sg.Button('Test'),
        sg.Button('Clear'),
        sg.Button('Exit')
    ],
]


# ----- Full layout -----
layout = [
    [
        sg.Column(file_list_column),
        sg.VSeperator(),
    ]
]

window = sg.Window("Network Troubleshooter", layout)

# Run the Event Loop
while True:
    event, values = window.read()
    if event == "Exit" or event == sg.WIN_CLOSED:
        break


    if event == 'Test':
        # Update the "output" text element to be the value of "input" element
        window['-NETWORK LIST-'].update(values['-IN-'])


    if event == 'Clear':
        # Update the "output" text element to be the value of "input" element
        window['-NETWORK LIST-'].update('')


window.close()

sg.Text is a label, no append function. You can do it by adding string to the current value of the displayed text, then update it.

text = window['-NETWORK LIST-']
text.update(text.get()+'New Text append')

There's no scroll bar for element sg.Text, sg.Multiline is preferred and same way to append text.
