									import struct

									from PyQt5.QtWidgets import (QMessageBox, QLineEdit)

									from PyQt5.QtGui import QPixmap

									{...}

									class LoginWindow(QtWidgets.QWidget):

									{...}

									  def __init__(self):

									    super(LoginWindow, self).__init__()

									    # 加载ui文件

									    loadUi('login.ui', self)

									    # 设置背景图片

									    background = QPixmap("img/login_background.jpeg")

									    background = background.scaled(self.background_label.width(),self.background_label.width())

									    self.background_label.setPixmap(background)

									    # 设置输入密码框

									    self.passwd_lineEdit.setEchoMode(QLineEdit.Password)

									{.......}

									def mainpage():

									  app = QtWidgets.QApplication(sys.argv)

									  login_window = LoginWindow()

									  login_window.show()

									  sys.exit(app.exec_())
