用wxpython 编写一个登录界面

好的，您可以参考以下代码来编写登录界面：

import wx

class LoginFrame(wx.Frame):
    def __init__(self, parent, id):
        wx.Frame.__init__(self, parent, id, '登录', size=(300, 200))
        panel = wx.Panel(self)

        # 用户名和密码文本框
        self.label_user = wx.StaticText(panel, label="用户名:")
        self.text_user = wx.TextCtrl(panel)
        self.label_pwd = wx.StaticText(panel, label="密  码:")
        self.text_password = wx.TextCtrl(panel, style=wx.TE_PASSWORD)

        # 登录和退出按钮
        self.button_login = wx.Button(panel, label="登录")
        self.Bind(wx.EVT_BUTTON, self.OnButtonLoginClick, self.button_login)
        self.button_cancel = wx.Button(panel, label="退出")
        self.Bind(wx.EVT_BUTTON, self.OnButtonCancelClick, self.button_cancel)

        # 添加布局管理器
        vbox = wx.BoxSizer(wx.VERTICAL)
        hbox1 = wx.BoxSizer(wx.HORIZONTAL)
        hbox2 = wx.BoxSizer(wx.HORIZONTAL)
        hbox3 = wx.BoxSizer(wx.HORIZONTAL)

        hbox1.Add(self.label_user, proportion=0, flag=wx.LEFT, border=5)
        hbox1.Add(self.text_user, proportion=1, flag=wx.EXPAND | wx.RIGHT | wx.TOP | wx.BOTTOM, border=5)
        hbox2.Add(self.label_pwd, proportion=0, flag=wx.LEFT, border=5)
        hbox2.Add(self.text_password, proportion=1, flag=wx.EXPAND | wx.RIGHT | wx.TOP | wx.BOTTOM, border=5)
        hbox3.Add(self.button_login, proportion=0, flag=wx.CENTER | wx.TOP | wx.BOTTOM, border=5)
        hbox3.Add(self.button_cancel, proportion=0, flag=wx.CENTER | wx.TOP | wx.BOTTOM, border=5)

        vbox.Add(hbox1, flag=wx.EXPAND | wx.LEFT | wx.RIGHT | wx.TOP, border=10)
        vbox.Add(hbox2, flag=wx.EXPAND | wx.LEFT | wx.RIGHT | wx.TOP, border=10)
        vbox.Add(hbox3, flag=wx.EXPAND | wx.TOP | wx.BOTTOM, border=10)

        panel.SetSizer(vbox)

    def OnButtonLoginClick(self, event):
        username = self.text_user.GetValue()
        password = self.text_password.GetValue()
        wx.MessageBox('您输入的用户名是：%s，密码是：%s' % (username, password), '登录结果')

    def OnButtonCancelClick(self, event):
        self.Close(True)

if __name__ == '__main__':
    app = wx.App()
    frame = LoginFrame(parent=None, id=-1)
    frame.Show()
    app.MainLoop()

这是一个使用 wxPython 编写的简单登录窗口，其中包含了用户名和密码文本框，以及登录和退出按钮。您可以通过调整布局管理器和控件属性来实现自己需要的窗口效果。
