View Full Version : [AS3] Dynamically instanciating an Astra Tree Component via AS3

11-03-2009, 03:35 AM
The Astra Tree Component (from developer.yahoo.com/flash/astra-flash/tree/) works great when I just drop it on the stage and give it an instance name and use it when Flash creates its definition.

Now I would like to be able to conditionally create an instance of the component via AS3, but when I say:

public var newTree:Tree;

I receive the following error:
1046: Type was not found or was not a compile-time constant: Tree.

I am importing com.yahoo.astra.fl.controls.treeClasses.*

If I change the declaration to

public var newTree:List;

Then I can use put the tree component on the stage and populate it, but I don't have access to the Tree methods like openAllNodes.

Would appreciate any suggestions.

you need to import the Tree classes in your AS

import com.yahoo.astra.fl.controls.Tree;
import com.yahoo.astra.fl.controls.treeClasses.*;

And make sure you have the Tree in your Library.
