TTreeView的使用方法请教
在c++ builder中的TTreeView控件如何添加子节点，根节点为Root，我想在添加子节点时用AddChildObject添加一个字符串和一个整数，当选中某个节点时能取出对应的整数值，请问怎么取出这个值呢？
[解决办法]
在建每个node的时候把他的AbsoluteIndex和数字一一对应放在一个TStringList中sg
在选中某个node的时候根据他的AbsoluteIndex去找数字
TTreeNode *node = TreeView1->Selected;
ShowMessage(sg->Values[IntToStr(node->AbsoluteIndex)]);
