Glad you got it figured out. Could you post your solution here for future

Re: [flexcoders] Re: Tree and array data
I think I am finally getting some where. In case you don't know what I have
been up to I will bring you up to speed. I am building a file explorer where
the left side will only be directories. When you select a directory the
contents (files) will show up in a datagrid on the right. I was having some
issue with display branches but I solved that by inserting an empty array on
any folder i knew had children.
Now I am trying to append the directories when the user starts drilling
down. So first I have an onItemOpen() method for when the folder is opened.
All this does is figure out the path and call my server side function that
will retrieve me a list of directories for a given path.
private function onItemOpen(event:TreeEvent):void {
var path:String = event.item.path;
FileManager.getDirectories(path);
}
I have a onResult method for the getDirectories() method called
listDirectories(). What I am doing here is
1. getting the list of directories.
2. if the tree data provider (_directorheies) is null we know this is the
base.
3. if not I am trying to figure out a way to append this array (or swap out)
with the children empty array i have as a placeholder.
Is this the right approach? I am obviously doing something wrong, hope
someone can point that out!
private function listDirectories(event:ResultEvent):void {
var dirs:Array = event.result as Array;
var parent:String = dirs[0].parent;
var pos:uint = -1;
// if the _directories array is null this is our root
request
if(_directories == null) {
_directories = dirs;
}else {
// we know the parent of the item that was clicked, find
the array position
for(var i in _directories){
if(_directories[i].path == parent){
pos = i;
break;
}
}
//if we found the position append the directories to the
children node
_directories[i].children = dirs;
trace(ObjectUtil.toString(_directories));
}
}
Re: [flexcoders] Re: Tree and array data
The Tree has styling for disclosure icons & folder icons. If you want
additional or different visual controls you will most likely need
to extend the TreeItemRenderer class and set it in the tree's
itemrenderer property. You can override the createChildren() function
to add any visual controls that can be toggled on/off based on values
in the node data object, like if your node object has a 'loading' attribute you
can use it to toggle a loading animation.

Thanks. i made i little changes to your sample, because having a
children arraycollection in class gets the tree control to always
display a folder icon. so this is the changed code. Thanks for the
kickstart.

public class Node

public function aArr(obj:Object = null):void
{
if (obj != null)
{
this.id = obj.id;
this.label = obj.label;
this.children = null; // to get a page icon in tree

[flexcoders] Re: Tree and Array
I would stick with what you know and used nested array collections. I
was about to implement this structure when I checked out flexcoders
and saw your post. This should help you out a bit:
1) make your array into a class.
package dto
{
import mx.collections.ArrayCollection;
[Bindable]
public class aArr
{
public var id:int=0;
public var description:String = "";
public var children:ArrayCollection = new ArrayCollection
public function aArr(obj:Object = null)
{
if (obj != null)
{
this.id = obj.id;
this.description = description.SD;
this.children = new ArrayCollection;
}
}
}
}
As you see you have to add an arraycollection to your class. This is
where your children will go.
2) Build your data from what ever your source is and put it in these
nested array collections. If i were to do these from a .net
webservice i would have it send over the data in a multidimensional
array. You can add the children to the correct parents with slick for
and if statements.
anyways, here is the code I would use to make a few layers(make sure
you put class above in a file named "aArr.as" in a folder named dto):
http://www.adobe.com/2006/mxml"; layout="absolute">
3) You can see that to add a child you do addItem(). You can also
specify where in the list you want to put the child with addItemAt().
I hope this helps. If you have problems getting ur array into this
nested array collection structure or finding out parents just reply
with a chunk of data and I'll show you how I would put it into this form.

Oops, the nodes should have been: var _xml:XML = ; var xmlNode:XML = ; You need to provide a property to use for the label, and then specify that as the labelField.

using this sample, i keep getting errors. so i included a closing root tag and a closing node tag. after this, seems to compile without errors, but the tree component displays the xml source beside the folder icon. do you know where i canfind a sample of: 1. create a new XML tree empty structure. 2. add nodes indicating the parent node i only need these two steps to do it all.

RE: [flexcoders] Re: Tree and Array
You must build either XML, or an ArrayCollection of ArrayCollections. Are you asking how to construct the logic to read your array and build the dataProvider? It will depend on the exact character of the array data. For example, are you assured that a parent will be defined before any of its children are?
