具有基本功能的矢量绘图软件实验报告

1、题目具有基本功能的矢量绘图软件院、系（部）专业及班级 学号姓名日期1题目要求使用VS环境编写MFC1程序，制作一个具有基本功能的矢量绘图软件。2需求分析教育资料本实验的 ”矢量绘图 ”软件是一个具有Office 视觉样式的单文档应用程序，在应用程序的主框架窗口中包含一个Ribbon 功能区，其中有两个标签选项卡： “主页”和“绘图” 。当选择“绘图”选项卡后， 将列出一些简单的绘图工具。 选择某个绘图工具后，既可以再客户区绘制相应的图形；单击面板上的“画笔颜色”或“填充颜色”按钮后，将淡出一个颜色对话框以分别设置绘图的颜色及填充图形的颜色，而当单击“文本” 按钮后，可以在客户区输入文本内容。3

2、 总体设计3.1 业务逻辑设计3选择绘图工具用户开始绘图是否更改颜色选择颜色绘制图形NC是否输入文字描述是否继续绘制图形输入文字是否输入文字描述二输出显示.3.2界面逻辑设计使用VS新建项目，选择 VC+颈下白M M MFC项目类型，在弹出的“应用程序类型”界面中选择如图所示，然后进行一系列的设置后生成所需界面。FC应用程序向导-MFCApplication6应用程序类型橇述应用程序推型 复含文档支持 文档模板属性数据庠支持 用户界面功能 高级功能 生成的美应用程序类型.'单个文档电)B舒义档电工反选项卡式文档急于对话据Q)使用HTML对话框©无墙醐MFC控件.嘴个顶线文档/
