Hi all,
I am using a default tree model with custom tree nodes to represent some data objects. These data objects are constantly changing and I do not always know which one the user is currently working with. DefaultTreeModel.nodeChanged(myNode) works nicely on an individual basis but I need something that will refresh the entire tree. DefaultTreeModel.reload() works but I lose the expanded tree path. Any suggestions? Thanks.....
 
I didn't say it. I'm just telling you what this tiny ad said.
