PySimpleGUI主题更新？

如何解决PySimpleGUI主题更新？

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

我有第二个可以更改当前主题的窗口，但是我一直在寻找一种更新主窗口的方法，我所能找到的就是该窗口需要关闭并重新打开。

我试图放入一个主要功能，但是我希望这是我出问题的地方。

我遇到以下错误：

====重新启动：C：\ Users \ brett \ DropBox \ bmw \ Lighting Programming \ example 11c.py ===追溯（最近一次通话）：文件 “ C：\ Users \ brett \ DropBox \ bmw \ Lighting Programming \ example 11c.py”，行 112英寸 “单击的按钮为“ {}””。format（event），NameError：未定义名称“ event”

我从主要示例操作的代码如下：

#!/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
    
def main_window(event,values):

    # ------ Menu DeFinition ------ #

    window = sg.Window('Everything bagel',layout,default_element_size=(40,grab_anywhere=False)     

    while True:

            break
        if event == 'Submit':

            new_theme_1 = sg.theme()
            new_theme_1 = theme_browser_window_1(new_theme_1)
            print(new_theme_1)
            sg.theme(new_theme_1)
            #sg.window.update
            break

    window.close()  
    return event,values



def main():

    #while True:
        event,values = main_window(event,values)
        #if event == sg.WIN_CLOSED or event == 'Cancel': # if user closes window or clicks cancel
        #    break
    
        
sg.popup('Title','The results of the window.','The button clicked was "{}"'.format(event),'The values are',values)

main()
exit()

感谢您的协助布雷特

解决方法

您的程序开始于 sg.popup（'标题'， “窗口的结果。”， “单击的按钮为“ {}””。format（event）， '值是'，值）事件在函数中定义，该函数在-main（）之后开始。

设置事件和值的默认值，例如0。
