I am fairly new to Flex 2. I want to build a functionality
where when I mouse over a node in an mx:Tree, a transient pop up
window is displayed withsome textual information about the node.
When the mouse is not over the node, the pop up would close.
I know how to create the pop up, but I am clear on how to
identify what node the mouse is over. Is there some method/event in
mx:tree that I can use for this purpose?
