I'm having trouble searching for a solution to this need: I have a tree controller bound to an array in my window controller. I populate it with top-level items, and they show up, but I'd like to defer populating the children of each item until the user actually clicks the disclosure triangle. Getting the children is time-consuming and expensive. Is there a way I can get it to show the disclosure triangle and then call me back when it's clicked open?
Thanks, -- Rick
