1. 设计一个窗体应用程序,模拟写字板应用程序的基本功能。具体功能要求如下: (1)“文件”菜单中有“新建”、“打开”、“保存”、“退出”子菜单。 (2)“编辑”菜单中有“剪切”、“复制”、“粘贴”、“撤销”、“重复”、“全选”子菜单。 (3)工具菜单中有“颜色”、“字体”、“状态栏”功能。 (4)帮助菜单中有“关于”菜单功能。 (5)实现“编辑”菜单中、“工具”栏目中“剪切”、“复制”、“粘贴”、“撤销”、“重复”、“全选”的功能。 (6)实现文件的新建、打开、保存功能。(利用RichTextBox控件) (7)文件菜单添加打开文本文件、保存文本文件菜单项,实现文件的打开、保存功能。(利用文件读写类)
提示: (1)添加菜单栏、工具栏、RichTextBox控件。 (2)在打开对话框中要想只显示文本文档,可以在通用对话框Filter属性中设置*.txt类别。richTextBox的LoadFile、SaveFile方法中要指定文件流为RichTextBoxStreamType.PlainText (3)点击菜单和工具栏相关按钮都实现同一个功能,所以会调用同一个方法。设计一系列公有方法实现相关功能。建议完成一个方法,就运行测试一个方法,问题解决后再编写下一个方法,避免出现太多错误。
