Instead of going through the index, you could iterate the selectedItems
and use e4x syntax to get the attribute you're looking for. selectedItem
and selectedItems are a direct link to the object in the dataprovider,
in this case XML objects:
private function onItemClick(event:ListEvent):void
{
trace("******");
for each (var item in tree1.selectedItems)
{
trace([EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> );
}
}
For your sample XMLListCollection, selecting a single item (in this
example the 1st) will yield:
******
1
And selecting all will yield:
******
76
3
1

Subject: [flexcoders] Please explain the Tree to me!!!!! Before I die
waiting!
Hi,
I have a tree filled with an XMLListCollection, all nodes are named
<node>.
The structure is like this:
<node locationid='1'>
<node locationid='3'>
<node locationid='76'/>
</node>
</node>
but on a much greater scale.
Now I have set the Tree component to allowMultipleSelection=true so
that the user can select multiple nodes, that works no problem. I have
also set an itemClick function to trigger when the user selects the
item or items. By doing this I can work out if one item is selected
or multiple:
if(Tree(event.target).selectedItem){
dosomethingforoneselection; //this works ok
}else if(Tree(event.target).selectedIndicies){
for(var i:int = 0;i<Tree(event.target).selectedIndicies.length;i++){
var h:int = int(Tree(event.target).selectedIndicies[i];
}
}
Ok, now I have the index of each item selected on the Tree, so how do
I get the locationid from the index?
Completely mind boggled!
Thanks ever so much if you can help!
Kind Regards,
Iain
