I whant to make a tree node selection in action script code. May be it is possible to send some type of message to a tree component to select node that I whant (for example with key 3). Just as tree selects node when somobody click on it. Is it possible?
You shold use as zeron said
expandChildrenOf(item:Object, open:Boolean)
expandItem(item:Object, open:Boolean, animate:Boolean = false, dispatchEvent:Boolean = false, cause:Event = null):
but you need to expand all parents of the disere node.
