超级列表框操作类、树型框操作类模块使用说明



一、编写说明

1、树形框类模块中使用了一个不公开的“树型框操作基类”，为了方便使用树形框句柄或直接使用树形框字节集数据，类模块程序中特意将其分别封装成了“树型框操作类”、“树型框句柄操作类”这两个公开类。请根据实际使用情况中不同的需求自行选用之。

2、为方便实现对外部进程中同类组件的控制和数据获取，类模块程序中特别编写了一个“外部控件操作类”用于对外部组件的全面控制，为超级列表框操作类、树型框操作类模块的附属引用类。当需要对其它组件进行相应的外部操作时，可参考使用这个类模块。

3、为实现方便程序代码的改编，此类模块的调用方式与支持库中相关组件的调用方式完全相兼容。-Super list box operation class, tree-box operation class module Descr iption written descr iption of the tree box class module using a public tree box operation base class, in order to facilitate the use of the handle of the tree box or directly tree fr a me byte set data class module program specifically to encapsulate became the " tree box operation class" , " tree box handle operation class two open class. Please choose to use according to the different needs of actual usage. 2, to facilitate the achievement of similar components in the external process control and data acquisition, prepared an " external control operation,"　in the class module program, especially for the comprehensive control of external components, for super list box operation class, tree subsidiary reference class type box operation class module. When external operations other components, refer to the use of this class module. 3, to facilitate the adaptation of the program code, such module call
