Re: [flexcoders] Error while doing the Linked list demo using flex

Hi, they are in the repository in the same folder. I think that the better
way to use it is like so:

var list:DataList = DataList.fromArray([1, 2, 3], int);
or
var list:DataList = DataList.fromVector(new int[1, 2, 3]);

Thank you for the reply. In that datalist.as file how do i import ListCell. 
Any help would be appreciated. 

Thank you,

Hi, I think I know this implementation, and, I don't really like it, so I've
made my own, you're welcome to try:
http://code.google.com/p/e4xu/source/browse/trunk/src/org/wvxvws/data/DataList.as
(+ dependencies)

Or from templates, if you are using FD:

stage.scaleMode = StageScaleMode.NO_SCALE;
   
stage.align = StageAlign.TOP_LEFT;
   
dll = new DLinkedList();
   
for (var i:int = 0; i  START_NODES; i++)
{
Alert.show(i am in forloop);
var node:Node = new Node();
//var node:UIComponent = new UIComponent();
trace(node);
node.removeEventListener(MouseEvent.MOUSE_UP,   
node.mouseHandler);
trace(node.removeEventListener(MouseEvent.MOUSE_UP,   
node.mouseHandler));
Alert.show(i am in outside loop);
 addChild(node);
trace(addChild(node));
dll.append(node);
}
   
addChild(canvas = new Shape());
