[flexcoders] Re: Auto expand TreeView on open - How?

2008-12-08 Thread jer_ela 
I tried 

menuTree.openItems = menuData..node; 

but the tree doesn't expand.

What does work for me is 

callLater(menuTree.expandChildrenOf, [menuTree.dataProvider[0], true]);

 Subject: [flexcoders] Auto expand TreeView on open - How?
 
  
 
 I want to auto expand my menu treeview immediately on open - the
 following code is called from thecreationComplete=initTree(); and
 expands the first node only. 
 
 Is there a way to expand all nodes - I can't seem to get this to work.
 (Other have reported problems so I wonder if this is supported)?
 
 TIA,
 Patrick

Taking the Expanding a Tree Node example from the Flex 3 Tree Control
help at
http://livedocs.adobe.com/flex/3/html/help.html?content=dpcontrols_8.htm\
l and modifying it slightly I get this example:

 private function initApp():void
 {
 var nodeList:XMLListCollection = myTree.dataProvider as
XMLListCollection;
 var nodes:XMLList = nodeList.source;
 expandSubNodes(nodes);
 }

 private function expandSubNodes(nodes:XMLList):void
 {
 for(var i:int = 0 ; i  nodes.length() ; i++)
 {
 var n:XML = nodes[i];
 if(n.children() != null)
 {
 myTree.expandItem(n,true,false);
 expandSubNodes(n.children());
 }
 else
 {
 break;
