View Full Version : [AS3] How to programatically add tree to stage?

01-08-2009, 08:14 PM
I'm trying to programatically add the YDN Tree to the stage via my document class. I'm clearly doing something wrong but I be stumped. This is what I am trying:

package {
import flash.display.MovieClip;
import com.yahoo.astra.fl.controls.List;
import com.yahoo.astra.fl.controls.treeClasses.*;
import com.yahoo.astra.fl.controls.Tree;

public class Main extends MovieClip {

public function Main() {

var myTree = new Tree();



I'm getting the errors

1017: The definition of base class List was not found.

and a bunch more like

1020: Method marked override must override another method.

I assume this is because List isn't found - and it doesn't appear to be in the Astra package I downloaded (http://developer.yahoo.com/flash/astra-flash/) - looking in the controls directory, it isn't there. Is this something I can import via flash instead?

Howdy and Welcome... :)

Why are you importing the List class??? I don't think that class even exists... Comment out that line and see if you are getting it further...

Here is the YDN page for the Astra Tree component...

Oh, I moved this thread to the Components forum... Please find the most appropriate forum and post your question... ;)

Hello, and thanks - didn't see the component forum :o

I was only trying to import the List class, because without it I get:

1017: The definition of base class List was not found.

And this error is actually pointing to line 37 in the Tree class, not in my Main document class... so I assumed it needed to be imported, but I agree - there doesn't seem to be one. Thus my confusion...:confused:

(Also I am aware of the YDN page, I've been using the examples in the last couple days playing around with their stuff.)

Well... Let me ask you this way... Do you have the List.as file existing in the com/yahoo/astra/fl/controls directory???

Nope - so I realize it's going to bust anyway... I'm just confused on why Tree is referencing it, or wondering if I am doing something else wrong, or dowloaded the wrong package? (I downloaded the lastest one)
