Hi,

I use JTree in combination with my own TreeModel. Whenever a new node is to
be inserted I call all listeners to tell them that the structure of the tree
has changed but nothing happens! The new nodes don't appear. What am I
missing? Removing nodes works perfectly...
I figured out that JTree registers itself as a listener but it doesn't seem
to react on changes. I changed the call from "treeStructureChanged" to
"treNodesInserted" - no success either and a look at the source of JTree
says me that the implementation of this method is empty.

Here's piece of the code that informs the listeners:
public void insertItemAdapter(TreeControl.Item abstractItem)
{
// I wrap my nodes into special adapters.
SwingTreeControlItemAdapter newItem =
  new SwingTreeControlItemAdapter(abstractItem);

 // Helps me to find the adapter.
 itemMap.put(abstractItem, newItem);

 // Create a treepath down from the new item up to the root.
 TreePath pathToRoot = getPathToRoot(newItem);

 // Iteratr all listeners.
 Iterator listenerIterator = listeners.iterator();
 TreeModelListener actListener;

 while(listenerIterator.hasNext())
 {
  actListener = (TreeModelListener)listenerIterator.next();

  actListener.treeStructureChanged(new TreeModelEvent(this,
   pathToRoot));
 }
}

Any ideas?

Thanks.
