For your content pane, I would use a JEditorPane. You can use the setPage(URL url) or setPage(String url) methods to display HTML pages in the JEditorPane. When loading these pages, the editor pane will follow anchors in the URL:
JEditorPane content = new JEditorPane();
content.setPage("http://java.sun.com/");The setPage method loads pages asynchronously, so it make take a moment for the document to appear. You can load pages from files on your local filesystem too:
// Continued from above..
File theFile = new File("C:/myFolder/myFile.html");
// You should specify the content type of the document when loading
// from elsewhere than a web server
content.setContentType("text/html");
// Load from URL: file:/c:/myFolder/myFile.html
content.setPage(theFile.toURL());Suppose there was an anchor tag named "summary" in your html document. To load the document and skip to that anchor, just give setPage() a URL with an anchor, just like in a web browser:
// Load from URL: file:/c:/myFolder/myFile.html#summary
content.setPage(theFile.toURL().toString()+"#summary");You can set up the JTree in the contents pane of your app so that when you double click a node, the URL corresponding to that node is loaded.
Hope this helps.
