登录界面弹窗（LoginDialog类）的调用方法：
import wxfrom ui.login_dialog import LoginDialogclass MainFrame(wx.Frame):def __init__(self, *args, **kw):# 确保父级的 __init__ 被调用super(MainFrame, self).__init__(*args, **kw)pnl = wx.Panel(self) # 主面板…………login = LoginDialog(compulsory_login_flag=False)print(login.user_info)…………
只需要在主窗口启动之前调用LoginDialog类，就能在主界面显示之前，先打开登录窗口，然后在LoginDialog类的_handle_before_close_dialog方法中，根据_compulsory_login_flag（强制登录标识） 类属性的值，判断是否允许用户跳过登录。
