Refresh components in a panel

Question

hi ,
How to refresh components present in a panel, i tried validate and revalidate...
actually i have text boxes and combo boxes in a panel and this panel changes for a tree event listener . i.e ,when ever i click on any of the childs in that tree the content present in the text boxes in that panel should get refreshed.as i am using the same panel for all the childs in that tree.
I would be grateful to you if you help me out of this problem.
Thanks

If your text boxes have to change when you click and depend on node names , you need to define a listener which gets control every time you click. In your listener, you may retrieve the node name, and therefore you are able to display what you want somewhere else (ie. Text boxes)
Here is an example that I have implemented myself :
       mytree.addTreeSelectionListener(new TreeSelectionListener() 
          public void valueChanged(TreeSelectionEvent e)
               node =  (DefaultMutableTreeNode)       mytree.getLastSelectedPathComponent();
               if(node == null)  return;
                TreePath tP = mytree.getSelectionPath();
                        String NodePath = tP.toString();  // same as a string
               if (node.isLeaf())
                    refreshTextBox(....)    //   do what you want here
               else
                      //   do what you want here
     );Hope this can help.
