/******
I need a faster "expandAll()" or "collaspeAll()" function for the Flex
Tree component.
I want to expand the Tree completely open or completely closed.
This is what I have so far, but its too slow for a Tree with many nodes
in it.
Plus it requires an item of the Tree to be selected first.
I think the reason it get slower is because the "Tree.openedItems"
property is an
Object containing all the opened items but not the one's I expanded at
one time.
Does anyone have cleaner,faster way?
*******/
private function expandAll(tree:Tree,open:Boolean):void
{
var opened:Object;
function expand(obj:Object):void
{
tree.expandChildrenOf(obj,open);
opened=tree.openItems;
for each(var o:Object in opened){
if(tree.isItemOpen(o) != open){
tree.expandItem(o,open);
}
}
}
expand(tree.selectedItem);
}
