python - 如何在此处使用 While 循环计时器？

Question

我有一个带有 while 循环的 GUI 应用程序。我在插入中断循环的 if 语句时遇到问题。我希望这是一个计时器，这样如果 60 秒内没有任何反应，while 循环就会中断。

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

如果您点击此链接查看文档:https://pysimplegui.readthedocs.io/#persistent-window-example-running-timer-that-updates

您将看到可以使用内置的time模块来告诉您现在是什么时间。您可以计算结束时间并等到那时:

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
