I've been working with a JTree based on a custom TreeModel.
Unfortunatly, I cant figure out how to force it to update the entire
tree-- there simply dosnt seem to be a way to say "OK, your data changed
so drastically, it's not even worth me telling you where to start".
I have tried the fireTreeStructureChanged event, but that only updates
the tree structure, leaving nodes that have changed only by name
unchanged and me cursing. I've also tried firing multiple events;
combinations of StructureChanged, and NodeChanged, and _almsot_ got what
I wanted.
Could someone give me an overview of what I need to do eventwise to
update the entire tree? 2 4146

How about if you set the data model for the JTree to null, then re-set it to
the new, changed data model?

Dosn't appear to work; I'd like to steer clear of recreating the
component itself, because I know it can be done without going to that
extreme.
thanks tho. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
