PySimpleGUI的使用封装

将每个窗口封装成一个class，窗口之间跳转，在窗口销毁和窗口打开中进行。

这里用登录注册作为示范：

带数据库版:

import gc
    import sys
    import PySimpleGUI as sg
    
    from db import Account
    
    
    class LoginWindow(object):
    
        def __init__(self):
            # UI一定要放在初始化里面，否则GC无法销毁。
            self.login_layout = [
                [sg.Text('账号'), sg.InputText(key='-username-')],
                [sg.Text('密码'), sg.InputText(key='-password-')],
                [sg.Button('登录', key='-button_login-'), sg.Button('注册', key='-button_register-')]
            ]
            self.login_window = None
            self.create()
    
        # 监听事件
        def listening(self):
            while True:
                event, values = self.login_window.read()
                # 监听X退出
                if event == sg.WIN_CLOSED:
                    break
                # 监听登录事件
                if event == '-button_login-':
                    username = self.login_window['-username-'].get()
                    password = self.login_window['-password-'].get()
                    # 这里使用peewee框架来操作SQLite数据库
                    accounts = Account.select().where(Account.username == username, Account.password == password)
                    if len([account for account in accounts]) == 0:
                        sg.popup_quick_message('账号或密码错误')
