• 阅读 998

在 Windows 操作系统中,记事本是一个小的应用程序,采用一个简单的文本编辑器进行文字信息的记

录和存储。请仿照 Windows 的记事本,开发一个属于自己的记事本(Notepad)功能

记事本的应该具备的功能,基本要求如下:

(1) 菜单栏中包含文件、编辑、查看和帮助菜单,具体如下图所示。 仿Windows下记事本小程序 (2) 文件菜单中具有新建、打开、保存、另存为、打印和退出功能,具体如下图所示。 仿Windows下记事本小程序 (3) 编辑菜单中具有的功能有撤销、重做、剪切、复制、粘贴、删除、全选以及查找和替换,具

体如下图所示。 仿Windows下记事本小程序 (4) 查看菜单中具有的功能包括字体、颜色等,具体如下图所示。 仿Windows下记事本小程序 (5) 帮助菜单中的“View Help…”可以查看帮助文档,“About Notepad…”可以查看记事本的当前

版本。帮助菜单中具有的功能具体如下图所示。 仿Windows下记事本小程序 仿Windows下记事本小程序 (6) 程序代码如下所示:
