基于PB的数据敏感TreeView控件的组件化开发

Package Development of Data Sensitive TreeView Control Based on PB

介绍了如何利用COM组件技术和PowerBuilder集成开发环境,制作显示关系数据库中具有层次关系数据的TreeView控件.文中重点阐述了PowerBuilder组件的制作方法,以及实现数据敏感的基本思想与规范.另外,对一些典型算法也做了简要说明.

This article introduces how to use COM module technology and PowerBuilder's IDE in making a TreeView control, which shows the levelrelation data in the relational database. The paper stressly expounds the making method of PowerBuilder package as well as the basic thought and criterion which realizes data sensitivity. Moreover, some typical algorithms are also explained briefly.
