如何在pysimplegui中更新布局中的天气信息，并在每次按下窗口中的“刷新”时显示它？

import PySimpleGUI as sg
import requests

layout = [
    [sg.Text("当前天气: ", key="-WEATHER-")],
    [sg.Button("刷新")]
]

window = sg.Window("天气信息", layout)

def get_weather():
    # 发送API请求获取天气数据
    response = requests.get("https://api.weather.com/...")
    weather_data = response.json()
    
    # 解析天气数据，获取所需信息
    temperature = weather_data["temperature"]
    conditions = weather_data["conditions"]
    
    return f"温度: {temperature}℃, 天气状况: {conditions}"

while True:
    event, values = window.read()
    
    if event == sg.WINDOW_CLOSED:
        break
    
    if event == "刷新":
        weather_info = get_weather()
        window["-WEATHER-"].update(weather_info)
