Hi, Here is a question that I have about JTree. I want to display hierarchial data using JTree. I dont think I have a problem doing the usual JTree display with collapse and expand. However I would like to implement the following functionality. When a user right clicks on a node he/she should be able to make that the root of the tree. Can someone help me understand how I can go about implementing this functionality. Thanks in advance.
Hi After adding an action-listener, mouse-listener or whatever, put this code ito the action-method: ((DefaultTreeModel)tree.getModel()).setRoot((DefaultMutableTreeNode)tree.getLastSelectedPathComponent()); that's it. Praiser

And maybe you have to append a reload() and an updateUI() method.
