RE: Slightly OT: Java, XML, JTree question


xml jtree
Your approach seems fine to me.

If I understand you correctly you need to be able to associate
a JTree tree node with a DOM node?

Try this: while you're constructing the JTree, and adding
DefaultMutableTreeNodes (which I assume you're doing), store
the associated DOM node as a 'user object' using the
setUserObject method [1].

That way you can then retrieve and manipulate it, in response
to tree events.

HtH,

a.lang.Object)
