本文介绍了使用wxPython创建用户登录界面的过程，包括界面布局、按钮事件绑定及输入验证。通过具体的代码示例，展示了如何设计美观且功能完整的登录界面，并实现基本的登录逻辑验证。

import wx


class MyFrame(wx.Frame):
    def __init__(self, parent, id):
        wx.Frame.__init__(self, parent, id, title="创建text contrl", pos=(100, 100), size=(400, 300))
        panel = wx.Panel(self)

        self.titile = wx.StaticText(panel, label='请输入用户名密码', pos=(140, 10))
        font = wx.Font(16, wx.DEFAULT, wx.FONTSTYLE_NORMAL, wx.NORMAL)
        self.titile.SetFont(font)
        self.label_user = wx.StaticText(panel, label='用户名', pos=(50, 50))
        self.text_user =wx.TextCtrl(panel,pos=(100,50),size=(235,25),style=wx.TE_LEFT)
        self.label_pwd = wx.StaticText(panel, label='密码', pos=(50, 90))
        self.text_pwd = wx.TextCtrl(panel, pos=(100, 90), size=(235, 25), style=wx.TE_PASSWORD)
        self.bt_confirm = wx.Button(panel,pos=(105,130),label="确定")
        self.bt_cancel = wx.Button(panel,pos=(200,130),label="取消")
