Method XbpTreeViewItem():getChildItems() Foundation
Returns all items of a sub-level
:getChildItems() --> aChildItems
The return value is an array which references in each element an XbpTreeViewItem object of the next sub-level. The length of the array corresponds to the number of items in the sub-level.
The method :getChildItems() is used to retrieve all XbpTreeViewItem objects that have been added with the :addItem() method (all items in the sub-level). Together with the method :getParentItem() an entire tree view can be analyzed if just one XbpTreeViewItem object in a program is known.
