[CTJUG Forum] Re: JTree problem

[Carl Olivier]

Not a paint(Graphics g) problem?   Mebe you need to refresh the item on screen?  Its been years sisnce I did any java gui/awt/swign development :)  But I recall that sometimes you needed to manually tell the object to repaint itself or update or something along those lines...   Rgds,   Carl From: CTJUG-Forum@googlegroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Enrico Goosen Sent: 02 March 2006 16:34 To: CTJUG-Forum@googlegroups.com Subject: [CTJUG Forum] JTree problem Hi All,   I’m experiencing a problem with a JTree which is really baffling me.   I’m trying to insert a node into a JTree on a specific user action using this code (taken from The Java Tutorial).   public DefaultMutableTreeNode addObject(DefaultMutableTreeNode parent,                                             Object child,                                             boolean shouldBeVisible) {         DefaultMutableTreeNode childNode =                 new DefaultMutableTreeNode(child);           if (parent == null) {             parent = rootNode;         }                 treeModel.insertNodeInto(childNode, parent,                                  parent.getChildCount());           //Make sure the user can see the lovely new node.         if (shouldBeVisible) {             tree.scrollPathToVisible(new TreePath(childNode.getPath()));         }         return childNode;     }   The problem is that the newly added node doesn’t display in the JTree??!   I’ve even added this to check that a node was in fact added:   return (DefaultMutableTreeNode)fTreeModel.getChild(rootNode, parent.getChildCount()-1);   and it returns the node that was added.   But the JTree doesn’t display the node.   Any ideas what I’m doing wrong?   Enrico Goosen Software Developer SAICOM TECHNOLOGY TEL:       +2721 555 0726 FAX:     +2721 555 0821 CEL:     +2783 305 5676 EMAIL: [EMAIL PROTECTED] This message was checked by NOD32 antivirus system. http://www.eset.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "CTJUG Forum" group.
