可视编程环境模型

Visual Programming Environment Model

当前的可视编程环境正在将所见即所得作为基本环境设计原则,并以基于消息处理的编程方式作为用户进行开发的主要方式。在这些基本原则下,出现了各类不同的可视编程环境,大致可以分为三类: 1)以资源方式来刻画用户界面。这类可视编程环境的编程和界面构造相互独立,其代表有VisualC^(++),Visual J^(++),Java Workshop,SymantecCafe等。这些工具是给专业人员使用的。

This paper defines a layer model of visual programming environment ,including components layer,system structure layer and representation layer. Components layer describes the internal implementation of the components. System structure layer is to describe the structure relationship, management relationship and user define relationship of the components designed by users. Representation layer will represent the three relationships and create the destination program according to these.
