The OpenToolsNode example hooks into several parts of the JBuilder API. It defines a new node type that knows how to deal with OpenTools manifest files (.opentools extension). For these nodes it defines a new EditorKit and Scanner to provide syntax highlighting within the editor. It adds a list of headers to the Structure Pane and links these back to their locations in the file. Popup menus in the Structure and Editor Panes let you easily add a new header to the file. And finally, an OpenTool personality lets you turn OpenTools support on or off in JBuilder 10 and up.
