Abstract
A particular node (24) in a tree structure (23) defined in a data processing system (10) may be selected for display as the root node in a tree structure display window (21). Once a particular node (24) is selected as the root node, only that portion of the tree structure branching from the selected node (24) is displayed. The portion of the tree structure (23) which does not branch from the selected node (24) is omitted from the display. In addition to the portion of the tree structure branching from the selected node (24), the system also displays a path map window (22) containing information about the portion of the tree structure omitted from the display. The path map window (22) may include a representation of the selected node (24) and a representation of each ancestor USA node for the selected node, all arranged in the order of the path from the actual root node to the selected node.
