如何使用 Python/PySimpleGUI 根据另一个选定的字段值禁用输入字段"combo list "？

Question

Dears，

如何根据另一个选择字段值Python/PySimpleGUI禁用输入字段。这个脚本的目的是：一旦从第一个"；组合列表"；，它将禁用相应的entery，第二个或第三个，或者两者都禁用，下面是我的脚本实现这一点的尝试，不幸的是，需要在事件循环中进行额外的调整才能实现。你能在这方面提供支持吗：

import PySimpleGUI as sg
layout = [
[sg.Text('Filed 1:', size=(15,1)), sg.Combo(['DisableField2', 'DisableField3', 
'DisableField2&3'], size=(25, 1), key='FIELD1')],
[sg.Text('Field 2:', size=(15,1)), sg.Input(key='FIELD2', size=(25,1))],
[sg.Text('Field 3:', size=(15,1)), sg.Input(key='FIELD3', size=(25,1))],
],
window = sg.Window('MAIN',  layout, finalize=True,element_justification='c')

while True:
event, values = window.read()
print(event, values)
if event == sg.WIN_CLOSED or event == 'Exit':
break
elif event == 'FIELD1':
window['FIELD1'].update(result2.upper())
if event == 'DisableField2':
window['FIELD2'].update(disabled=True)
elif event == 'DisableField3':
window['FIELD3'].update(disabled=True)
elif event == 'DisableField2&3':
window['FIELD2'].update(disabled=True)
window['FIELD2'].update(disabled=True)
window.close()

使用元素的方法update(disabled=True)禁用元素。

当enable_events=True时，该事件将是Combo元素的关键'FILED1'。

要禁用哪个元素是由Combo元素values['FIELD1']的值决定的，而不是由事件决定的。

import PySimpleGUI as sg
settings = ['DisableField2', 'DisableField3', 'DisableField2&3']
layout = [
[sg.Text('Filed 1:'), sg.Combo(settings, size=10, expand_x=True, enable_events=True, key='FIELD1')],
[sg.Text('Field 2:'), sg.Input(key='FIELD2', size=25, disabled_readonly_background_color="Gray")],
[sg.Text('Field 3:'), sg.Input(key='FIELD3', size=25, disabled_readonly_background_color="Gray")],
]
window = sg.Window('MAIN',  layout, finalize=True, element_justification='c')
while True:
event, values = window.read()
if event == sg.WIN_CLOSED or event == 'Exit':
break
print(event, values)
if event == 'FIELD1':
setting = values[event]
if setting == 'DisableField2':
window['FIELD2'].update(disabled=True)
window['FIELD3'].update(disabled=False)
elif setting == 'DisableField3':
window['FIELD2'].update(disabled=False)
window['FIELD3'].update(disabled=True)
elif setting == 'DisableField2&3':
window['FIELD2'].update(disabled=True)
window['FIELD3'].update(disabled=True)
window.close()
