Hi there,

Please help me along here.  JTree itself doesn't have a
fireTreeStructureChanged() method nor does my class which implements
TreeModel.  The only thing I could find in the JavaDocs at
http://java.sun.com/j2se/1.4.2/docs/api/

was an interface called TreeModelListener.  It has a declared method called
treeStructureChanged(TreeModelEvent e).  If I am to use this interface
somehow do I implement it in MyTreeModel class or do I subclass JTree and
implement it there?  I'm not quite sure how to set this up right.

Incidentally, I don't have JBuilder any more.  I'm currently just using Sun
One Studio 4.  Hope to purchase JBuilder again someday soon, but money is a
little tight right now. Just using this newsgroup for techical help.

Alan
