模块名称:ADO树型数据显示控件 v1.0
修改日期:2005.10.11
作者: 蒋文杰 三江文杰工作室
用途: 此为与ADO数据库捆绑在一起的专用显示数据库中树型结构表的控件,
要求数据库中的表要与控件同构,数据库控件必须用ADOquery,
表中的树型数据的字段要有:
1、唯一标识的结点ID号,整型,从1开始;
2、结点名称,字串型;
3、父结点的ID号,整型,0为没有父结点;
4、树型结点是否是叶子结点,是为0(默认),1为组结点;
(注:叶子结点人为决定,没有子结点可能为叶子,也可为空组,空组要加载none结点)
5、暂用字段,整数,取0或1,用于遍历一子树或删除子树-module name : ADO tree data Control v1.0 revision date : 2005 Author : le1 studio Jiangwenjie three purposes : this database with ADO tied to the dedicated database shows tree structure of the control table, request a table in a database with the same configuration control, database controls must ADOquery. the table chandeliers have data fields : one, the only logo node ID number, integer, from a start; 2, node name, string; 3, the father node ID number, integer, 0 for no father node; 4, the node tree leaves is whether the nodes, yes to 0 (the default), a group of nodes; (Note : the leaf nodes human decision-node not likely to leaves. it may also air group, Air Group to load none node) 5, with occasional field, integer, from 0 or 1, for traverse a subtrees or delete subtrees
