通用图形接口设计

The Design of a General Graphic Interface

介绍了基于ＰｏｗｅｒＢｕｉｌｄｅｒ５．０的通用图形接口设计思想．该接口可以让用户方便地定义图形数据窗口，实现了图形转换、动态显示图形的标签值、图形旋转、图形打印等功能，从而避免重复编写程序．

The design ideas for a graphic interface based on PowerBuilder5.0 are presented. The interface makes it convenient for the user to define the graphic data window without the necessity to write duplicate programs.
