RE: [flexcoders] TREE : TreeNode & TreeNode attributes creation

Why don’t you just use the parentNode.addTreeNode method?  You definitely don’t need to create your own TreeNode class to support this. 

 

var newNode = { operand: “+”, label: “LABEL”, type: “NODE” };

tree.selectedNode.getParent().addTreeNode(newNode);

Subject: [flexcoders] TREE : TreeNode & TreeNode attributes creation

 

Hi everybody,

 

I need your help to create new attributes to a TreeNode.

I created a button which call the function addNodeUp()

Inside this function is the following code :

 

 

 public var newNode:TreeNode;
 public var selectedNode:TreeNode;

addNodeUp()

{

  var parentNode:TreeNode=tree.selectedNode.getParent();

  var childArr:Array = new Array();
  childArr = parentNode.getChildNodes();

 

  newNode =  new TreeNode("label", "data", parentNode);
  newNode.setProperty("data", "data", false);
  newNode.setProperty("operand", "OPERAND", false);
  newNode.setProperty("operator", "+", false);
  newNode.setProperty("label", "LABEL", false);
  newNode.setProperty("type", "NODE", false);
     
  childArr.unshift(newNode);

}

 

My problem is that I don't create the differents attributes for my new TreeNode except the label property and the data property which exist by default.

Should I have to create a cuztomized TreeNode Class implementing the existing one?

Have I done the right (best?) steps to create a node TreeNode into my Tree?

 

Thank for your help!

 

David
