我试图创建这样的代码，当状态列表框中的“新交易”文本被选中时，策略输入框将变成一个用x、y、z填充的列表框。

import pandas as pd
import sys, psycopg2, os, xlsxwriter
import PySimpleGUI as sg
import datetime
import getpass
from datetime import date, timedelta
from sqlalchemy import create_engine

# from writing import daily_TDP

from test import conversion
from retrieval_functions import copy_report, word_found, word_row

user_name = getpass.getuser()
out_path= r'path/TRADE_JOURNAL.xlsx'
recovery_path = r'Y:\ERROR_FILE_TRADES_NOT_EXPORTED.xlsx'
recovery_path = recovery_path[0:9] + recovery_path[10:]

columns = ["STATUS", "SYMBOL","TRADE_TYPE","BROKER", "PRICE", "QUANTITY","STRATEGY", "DATE_TRADE"]
param = (20,1)

def TRADE_ENTRY(columns, param, out_path,recovery_path):
    sg.theme('Dark Brown 1')
    listing = [sg.Text(u, size = param) for u in columns]
    header =   [[x] for x in listing]
    core = [
   sg.Listbox(['In Book', 'New Trade', 'Old Book'],enable_events=True,key='TYPE26',size = (20,2)),
   sg.Input(size = param),
   sg.Input(size = param),
   sg.Input(size = param),
   sg.Input(size = param),
   sg.Input(size = param),
   sg.Input(size = param, key= 'STRAT')]

    mesh = [[x,y] for (x,y) in list(zip(listing, core))]   
    layout =[[sg.Button("SEND")]]+ mesh
    window = sg.Window('Trade Entry System', layout, font='Courier 12').Finalize()

    while True:
        event, values = window.read()
        if event == sg.WINDOW_CLOSED:
            break
        if event == "SEND":
            data = values
            print('DATA', data)
        elif event == "TYPE26":
            print('here')
            if values[event] == ['New Trade']:
                window["STRAT"].update(sg.Listbox(['X', 'Y', 'Z']))

    window.close()

TRADE_ENTRY(columns, param,out_path, recovery_path)

目前，当按下“new trade”时，它成功地打印了“here”，但很明显，我的代码无法将此策略输入框实际更改为列表框。
谢谢
