1、图形化界面设计的基本理解 当前流行的计算机桌面应用程序大多数为图形化用户界面(Graphic User Interface,GUI)。 即通过鼠标对菜单、按钮等图形化元素触发指令,并从标签、对话框等图型化显示容器中获取人机对话信息。Python自带了tkinter 模块,实质上是一种流行的面向对象的GUI工具包 TK 的Python编程接口,提供了快速...

saveData() event.accept() 主动调用组件通常在工作原理上较为简单,用户只需在界面上放置所需的组件(按钮、下拉框等),并将组件的信号和中层引擎暴露的功能函数连接上(参考上面的initUi和login方法) 对于一些我们希望保存下来省去每次输入麻烦的信息,这里推荐Python的shelve库,可以直接将Python中的数据对象以二进制的...
