From the developer:
The source of TreeIconDemo is a concrete example that includes HTML files. Selecting any branch node in the tree results in this file being displayed. When you select a leaf node (a book), this panel displayes an HTML file for thet book. This demo uses a split pane to separate the tree and this HTML view. Drag the divider up or down to change the space distribution.
