title: Programatically select a node in a SmartGWT treegrid
body: <p>I have a smartgwt treegrid, which, when expanding a group, I need to automatically select the first childnode of that group. I can get to the child, but I fail to see how to select the node.</p>
  
  <pre><code>    TreeGrid moduleTree = new TreeGrid();
      final Tree tree = new Tree();
      moduleTree.addFolderOpenedHandler(new FolderOpenedHandler() {
  
          public void onFolderOpened(FolderOpenedEvent event) {
              TreeNode[] children = tree.getChildren(event.getNode());
              if (children.length &gt; 0) {
                  // TODO
              }
          }
      });
  </code></pre>
  
  <p>Any Ideas?
  Thanks!</p>
