TreeView displays information in a hierarchical tree format similar to Windows Explorer or the Macintosh's Finder. You can customize the tree, by choosing the text font, icons, connector types, spacing and other properties. Since you structure the tree branches and supply the data for the node names, you have great flexibility to present a variety of different kinds of hierarchical data. Each node can report back both rollovers and mouse clicks, and automatically handles highlighting if you supply a highlight image.

Any type of hierarchical data that you want the user to browse and select can be presented with TreeView Xtra. The graphics below show a file browser and an interactive organizational chart.

Other applications include:

- Multi-tiered result records from a database query. Presenting the results in tree format rather than as a flat report enables the user to drill down quickly to the areas the user is interested in. For instance sales records could be presented organized by region, then salesperson within region, then product within salesperson.

- Navigational map of CD or web site.

- Displaying the structure of an XML document

- Collapsible outline for navigating an electronic book
