python - PySimpleGUI 主题更新？

问题描述

我是 Python 和 PySimpleGUI 的新手。我现在只是在使用 PySImpleGUI 网站上提供的 Everything Bagel 示例程序。

我有第二个窗口可以更改当前主题，但我一直在寻找更新主窗口的方法，我只能找到需要关闭并重新打开窗口。

我试图放入一个主要功能，但我希望这是我出错的地方。

我收到以下错误：

==== 重启：C:\Users\brett\Dropbox\bmw\Lighting Programming\example 11c.py === Traceback（最近一次调用最后）：文件“C:\Users\brett\Dropbox\bmw\Lighting Programming \example 11c.py", line 112, in 'The button clicked was "{}"'.format(event), NameError: name 'event' is not defined

我从主要示例中操作的代码如下：

#!/usr/bin/env Python3      
import PySimpleGUI as sg
import time

sg.ChangeLookAndFeel('GreenTan') 

def theme_browser_window_1(new_theme_1):

    layout_1 = [[sg.Text('Theme Browser')],
               [sg.Text('Click a Theme color to see demo window')],
               [sg.Listbox(values=sg.theme_list(), size=(20, 12), key='-LIST-', enable_events=True)],
               [sg.Button('Exit')]]

    #layout_tb = ""
    #layout_tb = layout_1
    window_1 = sg.Window('Theme Browser', layout_1)

    while True:  # Event Loop
        event, values = window_1.read()
        if event == sg.WIN_CLOSED or event == 'Exit':
            break
        sg.theme(values['-LIST-'][0])
        sg.popup_get_text('This is {}'.format(values['-LIST-'][0]))
        new_theme_1 = str(values['-LIST-'][0])
        print(values)
        print(new_theme_1)
        sg.theme(new_theme_1)
        print(new_theme_1)

    window_1.close()
    return new_theme_1
