MVC（Model-View-Controller）framework using Python ,Tkinter and SQLite

1.项目结构

sql:

CREATE TABLE IF NOT EXISTS School (SchoolId TEXT not null,  SchoolName TEXT NOT NULL,SchoolTelNo TEXT NOT NULL)

整体思路

  • Model：负责与 SQLite 数据库进行交互，包括创建表、插入、删除、更新和查询数据等操作。
  • View：使用 Tkinter 和 ttk.Treeview 创建用户界面，包含输入框、按钮和分页控件，用于显示数据并处理用户的交互。
  • Controller：处理用户界面的事件，调用 Model 中的方法进行数据操作，并更新 View 中的显示。

代码实现：
