NX二次开发树列表添加节点

 

 Node* newNode=treeControl->CreateNode("");新建节点，""节点名称，可以传值，也可以传空值。

treeControl->InsertNode(newNode,NULL,NULL,Tree::NodeInsertOptionLast);插入节点。

参数1：要插入的新节点；

参数2：父节点，如果有多级节点就需要传父节点，例如装配树，没有就传空；

参数3：上一个节点，没有就传空； 

参数4：插入类型枚举，一般插在尾部；

Node* newNode=treeControl->CreateNode("");
treeControl->InsertNode(newNode,NULL,NULL,Tree::NodeInsertOptionLast);
