Example

When applied to the TreeView object, this method adds a root-level TreeNode to the end of the TreeView. When applied to the TreeNode object, this method adds a child-level TreeNode to the end of the parent node's collection. This example shows the differences in this method when applied to the TreeView object and the TreeNode object.

function addNodeToTree(){
    var newNode = oTree.createTreeNode();
    newNode.setAttribute("text", "New Root Node");
    oTree.add(newNode);
    }
function addNodeToNode(){
    var parentNode = oTree.getTreeNode("0");
    var newNode = oTree.createTreeNode();
    newNode.setAttribute("text", "New Child Node");
    parentNode.add(newNode);
    }
