We cannot add nodes to a Swing JTree node dynamically at
runtime. Jtree does not provide a method that is called before a node is expanded to display its children. There is a need to be able to manage/alter a nodes children, and select the children for display at the time the user clicks the node handle(The plus sign in the basic U/I).

Using the TreeCellExpanded event is insufficient as this event is sent after the cell has been expanded and all children painted.

Perhaps a TreeCellAboutExpand event or method needs added. This needs to be added to the Swing JTree design.
