Re: [flexcoders] Fw: [BETA3] I found how can remove the selected item of mx.controls.Tree.
My understanding was that the XMLListCollection methods would
handle the needed events, but apparently not.
Well, it should, and maybe this just isn't completly worked out yet in
the Tree class. When you do anything to a collection be it XML or
Objects, it will produce a COLLECTION_CHANGE event that has the
CollectionEventKind type that you then use to figure out what happened.
I know the Tree is pipped into this when the dataProvider is set. Must be a bug or something that is not completly wired.
Peace, Mike

invalidateList to get the tree to refresh. My understanding was that the

Hi,
all.
var

{
treeDD.removeChildAt ( parentItem,
mxTree.selectedItem, i );break;
}
}

It is
lengthy. so..
Iwant
Anyone who has idea other to know simple
code rather than above.
Thank
