摘　　要：GEF是Eclipse平台首要框架之一,其设计模式可很好地支撑可视化设计功能。Flex作为一种主流的富客户端开发技术,在前端展现和图形化设计上优势显著。文章首先对Flex技术进行了简要介绍,然后模拟Eclipse GEF,采用Flex技术设计了一套轻量级的Flex GEF框架,并给出该框架的设计思路和和扩展性设计方案,最后以流程设计器为例展示了Flex GEF框架的一个典型应用。GEF is one of the primary frameworks at the Eclipse platform. Its design pattern may be greatly helpful to support visualization design. As a leading technology for the development of rich clients, Flex shows a significant advantage on graphical front-end design. This paper gives a brief introduction to Flex, and then simulates Eclipse GEF to design a lightweight Flex GEF framework using Flex technology. Further, the design ideas and expandability of the proposed framework are depicted in detail. Finally, application of Flex GEF framework to process designer is shown as a typical example.
