Needing wisdom re NetBeans Outline ("tree table") component

skiaddict1

Greetings all,

I realise I should be posting this on a netbeans forum, and I have already done so, but no-one seems to want to reply over there... :-< So I'm hoping someone here has some relevant experience with this component.

I have two questions:

1. Has anyone managed to get notifications when the user edits a node in the tree part of the treetable? I can get the nodes to be editable, I can type in a change to the text there, but I'm not getting any notification of the change! I have tried registering the Outline model as a TreeModelListener and implementing treeNodesChanged(). I have tried registering the Outline as a TableModelListener and implementing tableChanged(). Nothing is working: I don't get the notifications. Does some kind person have some sample code, or a pointer to some, which would get me going in the right direction? Unless absolutely necessary I would rather not post my code, since it's "complicated"... ;->

2. Can anyone confirm whether this component supports drag 'n' drop? I haven't even started on that journey yet, so knowing "yes" or "no" would be very helpful.

Grateful thanks, as always, for any and all help :->

(Responding to my own thread in case the following is of use to someone else someday...)

Here is how to get this to work:

private class TreeTable extends Outline implements TableModel
{
  public void setValueAt(Object aValue, int rowIndex, int columnIndex)
  {
    NodeObjectType node= (NodeObjectType) getPathForRow(rowIndex).getLastPathComponent();
    System.out.println("The user has finished editing the node.");
    System.out.println("Old value: " + node.toString());
    System.out.println("New value: " + aValue);
  }
  public TreePath getPathForRow(int rowInUI)
  {
    int row = convertRowIndexToModel(rowInUI);
    if (getLayoutCache() != null)
    {
      return getLayoutCache().getPathForRow(row);
    }
    else
    {
      return null;
    }
  }
...
}

where NodeObjectType is the object that you are using for each node of the tree.

I haven't yet gone into drag 'n' drop, so I can't advise anything on that one. TIA still for tips & pointers with that :->
