Subject: [flexcoders] Traversing a
Tree
I'm having trouble writing a simple function that
expands all the
nodes in a Tree. Is there a method that returns
the number of nodes?
If there is, I think I could replace my callto
size() in the code
below with a call to this method and this would
work:
<mx:Tree initialize="openTree()">
<mx:Script>
<![CDATA[
function openTree()
{
for(var
i=0; i<this.size(); ++i)
this.setIsOpen(this.getTreeNodeAt(i), true);
}
]]>
</mx:Script>
<mx:Model id="TreeXML"
source="Source.xml"/>
<mx:dataProvider>
{ThreadXML}
</mx:dataProvider>
</mx:Tree>
Or is there a better way to traverse the Tree,
perhaps recursively?
