Hi,
Can someone please explain to me what TreeSelectionListener()or a TreeSelectionEvent is and what they do?
My main reason for asking is beacuse when i try to use a DefaultTreeModel method...RemoveNodeFromParent(), i get a :
Exception occurred during event dispatching:
java.lang.NullPointerException
and it referrs back to my use of TreeSelectionListener() and TreeSelectionEvent.
If you can give any help or guidence, it would help greatly. Thank you, mpap

Well, these are all classes found in the javax.swing package, which has nothing to do with XML. I'll move this topic to the Swing forum instead, where someone will hopefully answer it for you.
