Re: [flexcoders] Fully Expand Tree in Flex Beta 3

[Michael Schmalle]

Oh yeah,

Implementation;

tree.expandChildrenOf(tree.selectedItem, true);

The first param is whatever node you want all the children opened or closed of.

            Howdy all!

I've been searching and searching and trying to figure out how to 
convert the code floating around out there that fully 
expands/collapses a tree.  Can someone give me a hand with this.  
I've got the following:

	function expandTree(t:mx.controls.Tree) : Void {
        var i:Number=0;
        var node:mx.controls.treeclasses.TreeNode=t.getTreeNodeAt(i);
        while (node != undefined){
        	if (t.getIsBranch(node) && ! t.getIsOpen(node)){
                t.setIsOpen(node,true);
            }
            i++;
            node=t.getNodeDisplayedAt(i);
        }
	}

but i've been unsuccessful in finding the appropriate classes for 
getTreeNodeAt and TreeNode.  I read somewhere to use 
ITreeDataDescriptor but it does not work with DisplayObjects 
(getChildAt).  Someone please help! :)

Thanks!
