软件实习项目4——校园一卡通管理系统（代码实现）

  • 一、窗口的互相调用与各种功能的实现
    • 1、main.py
    • 2、LoginWindow.py
    • 3、ForgetWindow.py
    • 4、MainWindow.py
    • 5、InsertWindow.py （单个记录的插入）
    • 6、BatchInsertedWindow.py（Excel表格批量插入数据）
  • 二、连接和操作数据库的方法
    • Functions.py

(省去了各UI文件以及其转成的py文件)

一、窗口的互相调用与各种功能的实现

1、main.py

from PyQt5.QtWidgets import QApplicationfrom BatchInsertedWindow import BatchInsertedWindow
from ForgetWindow import ResetWindow, SecurityQuestionWindow
from LoginWindow import LoginWindow
from MainWindow import MainWindow
from InsertWindow import InsertWindow
import sysif __name__ == "__main__":app = QApplication(sys.argv)login_widget = LoginWindow()  # 窗口控件login_widget.show()main_widget = MainWindow()  # 窗口控件forget_widget = SecurityQuestionWindow()  # 密保窗口reset_widget = ResetWindow()  # 重置密码窗口insert_widget = InsertWindow()  # 窗口控件batch_insert_widget = BatchInsertedWindow()  # 批量插入窗口login_widget.signal.connect(main_widget.show)  # 连接槽函数login_widget.forget_signal.connect(forget_widget.show)  # 显示忘记密码窗口forget_widget.signal.connect(reset_widget.show)  # 显示重置密码窗口forget_widget.back_signal.connect(login_widget.show)  # 显示登录窗口reset_widget.signal.connect(login_widget.show)  # 回到登录窗口reset_widget.back_signal.connect(login_widget.show)  # 回到登录窗口main_widget.batch_signal.connect(batch_insert_widget.show)  # 显示批量插入窗口main_widget.insert_signal.connect(insert_widget.show)  # 连接槽函数insert_widget.inserted_signal.connect(main_widget.query)  # 更新数据sys.exit(app.exec_())

2、LoginWindow.py
