How to While loop timer in here?

I have a GUI app with a while loop. I'm having trouble inserting an if statement that breaks the loop. I want this to be a timer so if nothing happens in 60 seconds the while loop will break.

layout = [[sg.Text('Velg mappe som skal tas backup av og hvor du vil plassere backupen')],
          [sg.Text('Source folder', size=(15, 1)), sg.InputText(a), sg.FolderBrowse()],
          [sg.Text('Backup destination ', size=(15, 1)), sg.InputText(b), sg.FolderBrowse()],
          [sg.Text('Made by XXX™')],
          [sg.Submit("Kjør"), sg.Cancel("Exit")]]
window = sg.Window('Backup Runner v2.1')

while True:  # Event Loop
    event, values = window.Layout(layout).Read()
    if event in (None, 'Exit'):
        sys.exit("aa! errors!")
        print("Skriptet ble stoppet")
    if event == 'Kjør':
        window.Close()
        break

If you follow this link to the docs: https://pysimplegui.readthedocs.io/#persistent-window-example-running-timer-that-updates

You will see that you can use the built-in time module to tell you what the time is now. You could calculate the end time and just wait til then:

import time

layout = ...
window = sg.Window('Backup Runner v2.1').Layout(layout)

end_time = time.time() + 60

while True:  # Event Loop
    event, values = window.Read(timeout=10)
    # Your usual event handling ...

    if time.time() > end_time:
        break

The simplest way in PySimpleGUI to do this is to set the timeout value in the call to window.Read().

This code will wait for user input for 60 seconds. If none is received, then you will get a "Timeout Key" value returned to you from the Read call.

Note that you should not be calling Layout inside of your while loop. This is more like what you need:

while True:  # Event Loop
    event, values = window.Read(timeout=60*1000)
    if event in (None, 'Exit'):
        sys.exit("aa! errors!")
        print("Skriptet ble stoppet")
    if event == 'Kjør':
        window.Close()
        break
    if event == sg.TIMEOUT_KEY:
        break

You could try this with time module:

import time

seconds = int(time.time()) # This is seconds since epoch
while True:
    if int(time.time()) > seconds + 60: # True when seconds + 60 < current seconds
        break # End of your loop
