Method; returns the display index of the node specified in the
The display index indicates the item's position in the list of items that are visible in the tree
window. For example, any children of a closed node are not in the display index. The list of
display indices starts with 0 and proceeds through the visible items regardless of parent. In
other words, the index is the row number, starting with 0, of the displayed rows.

The following example adds six nodes to a Tree and calls
position of the node that the user selects.
You must first add an instance of the Tree component to the Stage and name it
