提出了一个GDI+和设计模式相结合的设计方案.首先介绍一种分层式文档-视图框架.在此框架基础上,分析几种重要交互功能如图元组合、undo/redo、图面缩放及橡皮筋线的设计过程.使用结果表明,构建的平台满足交互功能需求,并具有良好的可复用性.
We propose a platform built by GDI+ and design patterns.Firstly,a hierarchical document-view framework is introduced.Then,we analyze the design process of important interactive features which are composite of graphics element,undo/redo,zoomin/out and rubber line.The results show that platform is meet the needs of interactive features and has good reusability.
