How can I display nodes in a tree in alphabetical order?

Simon Brown

You should ensure that you underlying data is sorted when your tree model is built. For example, if building a TreeModel based upon a list of objects, you could sort the list using the Collections.sort() method and optionally, a Comparator.

[FAQ Manager Note] Alternatively, you could create a filtering model that changes the order of nodes as they're requested. This allows you to have mulitple sorting orders on the same actual data.

See http://www7.software.ibm.com/vad.nsf/Data/Document2329 for some examples of this, using a TableModel. You could do similar processing with a TreeModel.
