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语句时遇到麻烦。我希望这是一个计时器,所以如果60秒内没有任何反应,则while循环将中断。
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

如果您点击以下指向文档的链接:https://pysimplegui.readthedocs.io/#persistent-window-example-running-timer-that-updates
您将看到可以使用内置的time
模块来告诉您现在几点了。您可以计算结束时间,然后一直等到:
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

您可以使用时间模块尝试此操作:
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

在PySimpleGUI中执行此操作的最简单方法是在对timeout
的调用中设置window.Read()
值。
此代码将等待用户输入60秒钟。如果未收到任何消息,那么您将获得Read
调用返回的“超时密钥”值。
请注意,您不应在while循环内调用Layout。这更像您所需要的:
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
