如何解决PySimpleGUI 项目集成的“KeyError”
import PySimpleGUI as sg
import os
def page2b():
company_list_column = [
[sg.Text('Pick your company name')],[sg.ListBox(os.listdir("C:\/FYP\/GUI\/Companies"),size=(25,5),key='-EC-',enable_events=True)]
]
company_column = [
[sg.Text(size=(40,1),key='-Company Selected-')],[sg.Text(size=(40,key='-Folder Selected-')],]
layout = [
[sg.Text('Select your Company',justification='center',font=("Arial",22))],[
sg.Column(company_list_column),sg.VSeparator(),sg.Column(company_column),],[sg.Button('Select Company'),sg.Button('Close')]
]
return sg.Window('Baseline Analyzer',layout,default_element_size=(100,auto_size_buttons=False,default_button_element_size=(12,size=(600,270))
window= page2b()
while True: # the event loop
event,values = window.read()
if event == sg.WIN_CLOSED or event == "Close":
break
if values['-EC-']: # if something is highlighted in the list
window['-Company Selected-'].update(f"Company selected: {values['-EC-'][0]}")
window['-Folder Selected-'].update(f"Your folder is: C:\FYP\GUI\Companies\{values['-EC-'][0]}")
if event == "Select Company": #The path of the folder to store the things at
word= {values['-EC-'][0]}
word = "".join(word)
foldername = "C:\FYP\\GUI\\Companies\\" + word
break
window.close()
总而言之，这将显示一个公司文件夹列表供我选择，当我单击一个文件夹时，我会看到实际选择的文件夹是什么，如下面的屏幕截图所示：
作为一个独立的程序，上面的页面工作得非常好。但是，当我尝试将其集成到我的主程序中时，如下所示：

window.close()
我遇到了这个“keyError”并且一直在琢磨如何解决它
Traceback (most recent call last):
File "c:\Users\******\Documents\******\******\testing.py",line 140,in <module>
if values['-EC-']: # if something is highlighted in the list
KeyError: '-EC-'
有没有办法解决我的困境？
解决方法
行 window = page2b() 创建新窗口，但它不会更新 window,event,values 中的值 - 它需要再次运行 sg.read_all_windows()
因此您应该直接在 if values['-EC-'] 中运行 while True。但是它将为每个窗口执行，因此您必须检查 if '-EC-' in values and values['-EC-'] 或者您必须检查 if window == window2 但它也需要使用 window2 = page2b() 而不是 window = page2b() 甚至更好window2b = page2b() 以识别您是否运行 page2a 或 page2b
# ---
window1 = page1()
window2a = None
window2b = None
while True:
window,values = sg.read_all_windows()
#print('window:',window)
#print('event:',event)
#print('values:',values)
if event == sg.WIN_CLOSED or event == 'Exit'or event =='Close':
window.close()
if window == window2a:
window2a = None
elif window == window2b:
window2b = None
elif window == window1:
break
elif event == 'Clear':
clear_input()
# - events,values unique for every window -
if window == window1:
if event == 'New Company':
window2a = page_2a()
elif event == 'Existing Company':
window2b = page2b()
elif window == window2a:
# ... code ...
pass
elif window == window2b:
if values['-EC-']:
window['-Company Selected-'].update(f"Company selected: {values['-EC-'][0]}")
window['-Folder Selected-'].update(f"Your folder is: C:\FYP\GUI\Companies\{values['-EC-'][0]}")
if event == "Select Company":
word = {values['-EC-'][0]}
word = "".join(word)
foldername = "C:\FYP\\GUI\\Companies\\" + word
window.close()
甚至
window1 = page1()
window2a = None
window2b = None
while True:
window,values)
if window == window1:
if event == sg.WIN_CLOSED or event == 'Exit'or event =='Close':
window.close()
break
elif event == 'New Company':
window2a = page_2a()
elif event == 'Existing Company':
window2b = page2b()
elif window == window2a:
if event == sg.WIN_CLOSED or event == 'Exit'or event =='Close':
window.close()
window2a = None
elif event == 'Clear':
clear_input()
elif window == window2b:
if event == sg.WIN_CLOSED or event == 'Exit'or event =='Close':
window.close()
window2b = None
elif values['-EC-']:
window['-Company Selected-'].update(f"Company selected: {values['-EC-'][0]}")
window['-Folder Selected-'].update(f"Your folder is: C:\FYP\GUI\Companies\{values['-EC-'][0]}")
elif event == "Select Company":
word = {values['-EC-'][0]}
word = "".join(word)
foldername = "C:\\FYP\\GUI\\Companies\\" + word
编辑：
其他想法是为每个窗口创建新的 while 循环，但有时它的工作方式可能与以前的版本不同。当 window2 打开时，它会阻止 window1 中的按钮，因此您不能同时打开两个 windows 2。以前的版本可以同时打开New Company','Existing Company - 它甚至可以打开许多Existing Company和许多'新公司 at the same time. This version can open only one 'New Company或只有一个Existing Company并且它可以打开{{1} } 同时。
在新版本中，当 New Company','Existing Company 打开时，您不能在 Exit 中使用 window1。
我更改了 window2 中的路径以在我的系统上运行它。
