Message not displaying with PySimpleGUI

I have a project where I'm trying to build a simple time-clock using Python 3 on a Raspberry Pi. The Pi is running 64-bit Bullseye.
In my script, I create a window with two columns, one for entry and one for display. The entry side is working (as far as I have gone). The display side sorta works, and this is the issue.
The user will enter their code, press "Enter" to see their information, and then press "In" or "Out" for clocking in or out. When the user presses "In", I want to display a message that says either "Clocked In" or "Already Clocked in".
The issue is that the clocked-in message does not display. The statement that fails is the msg_elem.Update( .... If I run the Python debugger, the message is displayed, but not in "normal" running.
My question is What am I doing wrong?
This is a working example...

# ###EOF###
I have tried this on the RPi, and on a Virtual system with Debian (not Pi) linux. Both give me the same result. I've searched here on Stack Overflow, and Google in general, and I think I'm doing it correctly, but failing.

The method msg_elem.Update just update the architecture of PySimpleGUI, not the GUI. Need to call window.refresh() before sleep(10) if you want the GUI updated immediately, not until back to window.read(). sleep(10) take long time for GUI to wait, so it will show "Not Responding".

Update Values in PySimpleGui from external script

I am new to PySimpleGui and wonder if the following concept can be applied.
I have to work with two scripts, one related to a GUI and a second one that it is a "Do Something Script".
I am interested in printing the status of an external loop in a window of my GUI Script
The GUIScript that I have coded as an example is the following:
import PySimpleGUI as sg
import MainScript
### GUI Script ###
layout = [
[sg.Text('My text 1 is: '), sg.Text('{}'.format('foo1'), key='-text1-')],
[sg.Text('My text 2 is: '), sg.Text('{}'.format('foo2'), key='-text2-')],
[sg.Text('Sweep number: '), sg.Text('{}'.format('0'), key='-SWEEP-')],
[sg.ProgressBar(max_value=40, orientation='horizontal', size=(50,20), key='-PRO_BAR-')],
[sg.Button("OK"), sg.Button("Cancel")],
]
window =sg.Window("Progress Bar",layout)
while True:
event, values = window.read()
if event == 'Cancel' or event == sg.WIN_CLOSED:
break
if event == "OK":
for s in range(50):
event, values = window.read(1000)
if event == 'Cancel':
break
window['-PRO_BAR-'].update(s+1)
window['-text1-'].update('my new text1')
window['-text2-'].update('my new text2')
window['-SWEEP-'].update(s)
window.refresh()
window.close()
The previous script works as "what I would like to have". I mean that the window['-PRO_BAR-'].update(s+1) and window['-SWEEP-'].update(s) update according to the s value of its own for-loop.
However, I would like to pick up the variable=i from the MainScript (which is the following), and use it back in the GUIScript.
##### MainScript ####
SWEEPS = 50
SWEEPS_LEN = list(range(1, SWEEPS+1))
for i in enumerate(SWEEPS_LEN):
print('sweep: {}'.format(i))
# Do something
# Save Data
Here, it is obvious that i=0, i=1, i=2.... I want to use these variables (that change in the loop) them as:
window['-PRO_BAR-'].update(i+1) and window['-SWEEP-'].update(i), such as the values update.
The GUIScript would show:
Sweep: 1
then i=2, updates and shows
Sweep: 2
then updates and...
Thanks.

Text not updating in PySimpleGui

In my code, Im trying to make a calculator. So there is a 1 button which when pressed, updates the Question: text by adding 1 to it's text. So when I press 1, the text will convert from Question: to Question: 1. But its not updating. I have faced this problem before too. I think when I do the .update, it will only update the value till its the same number of letters as the text already has. If it has 2 letters and I try to .update('123'), it will only update to 12. Is there any way to get around this???
import PySimpleGUI as sg
layout = [
[sg.Text('Question: ', key='-IN-')],
[sg.Text('Answer will be shown here', key='-OUT-')],
[sg.Button('1'), sg.Button('2'), sg.Button('3')],
[sg.Button('4'), sg.Button('5'), sg.Button('6')],
[sg.Button('7'), sg.Button('8'), sg.Button('9')],
[sg.Button('Enter'), sg.Button('Exit')]
]
window = sg.Window('calculator', layout)
while True:
event, values = window.read()
if event is None or event == 'Exit':
break
elif event == '1':
bleh = window['-IN-'].get()
teh = f'{bleh}1'
window['-IN-'].update(value=teh)
window.close()

As above comment, Example like this,
import PySimpleGUI as sg
layout = [
[sg.InputText('Question: ', readonly=True, key='-IN-')],
[sg.Text('Answer will be shown here', key='-OUT-')],
[sg.Button('1'), sg.Button('2'), sg.Button('3')],
[sg.Button('4'), sg.Button('5'), sg.Button('6')],
[sg.Button('7'), sg.Button('8'), sg.Button('9')],
[sg.Button('Enter'), sg.Button('Exit')]
]
window = sg.Window('calculator', layout)
input = window['-IN-']
while True:
event, values = window.read()
if event is None or event == 'Exit':
break
elif event in '1234567890':
bleh = window['-IN-'].get()
teh = f'{bleh}{event}'
input.update(value=teh)
input.Widget.xview("end") # view end if text is too long to fit element
window.close()

Button Non-Event-Driven Model

First, I have read the docs. I understand that the information is stored in Key= x. My issue is when I call a function from another file it does not recognize x.
I have read the docs, but failing to understand how to use the key
I tried putting x into a variable and passing it to the function.
File 1
def add_details():
today1 = date.today()
today2 = today1.strftime("%Y/%m/%d")
create = str(today2)
name = str(_name_)
reason = str(_reason_)
startDate = str(_startDate_)
endDate = str(_endDate_)
add_data(create,name,reason,startDate, endDate)
def add_data(create,name,reason,startDate, endDate):
engine.execute('INSERT INTO schedule(Created_On, Fullname, reason, Start_Date, End_Date ) VALUES (?,?,?,?,?)',(create,name,reason,startDate,endDate))
File 2
while True:
event, values = window.Read()
print(event, values)
if event in (None, 'Exit'):
break
if event == '_subdate_': #subdate is the button Submit
sf.add_details()
My expected results are that the inputs of the GUI are passed to the function, then off to a SQLite db.
Error: name 'name' not defined
(or any key variable)

This is an example that you'll find running on Trinket (https://pysimplegui.trinket.io/demo-programs#/demo-programs/design-pattern-2-persistent-window-with-updates)
