3、其他程序时，这些格式可以向您提供更大的灵活性。应将使用多种语言的文档保存为多信息文本文件 (.rtf)。菜单栏和工具栏完成几乎相同的功能，但是表现形式不同，状态栏能够提供提示信息，为用户的使用带来方便。1.3. 可选要求在完成windows系统自带写字板的基本功能的前提下，扩充有自己特色的功能。如加入计算器等系统工具。1.4. 运行环境由于是使用的是c语言，在.net framework类库的框架下完成的，所以必须在windows环境下才能完成本次软件课设任务。我使用的操作系统就是windows xp.202. 系统描述2.1. 系统功能及特点 创建、打开或保存“写字板”文档。 根据窗口大小换

4、行。 撤消上一次操作，或重复上一次操作。 查找或替换特定的字或词。 显示或隐藏“写字板”工具栏。 剪切、复制、粘贴或删除文本。 创建项目符号列表。 更改字体、字形或大小。 段落缩进。 更改段落对齐方式。 状态栏显示操作时的基本提示信息。2.2. 系统运行效果图 1系统运行效果图3. 数据结构描述由于这个多功能文本编辑器是小组成员一起完成的，所以每个人都有自己的职责,我负责的是状态栏部分和菜单栏中的部分选项。我在这次任务中编写了2个类：status.cs、menu.cs，下面一次介绍。3.1. status.csusing system;using system.collections.gene
