Code:
import org.richfaces.component.UITree;
import org.richfaces.event.NodeSelectedEvent;
import org.richfaces.model.TreeNode;
import org.richfaces.model.TreeNodeImpl;
public class MyTreeBean {
private TreeNode<String> root = new TreeNodeImpl<String>();
private static int id = 0;
public MyTreeBean() {
final int FIVE = 5;
TreeNodeImpl<String> temp;
for (; id < FIVE; id++) {
temp = new TreeNodeImpl<String>();
temp.setData("Node #" + id);
root.addChild(id, temp);
}
}
public void selectionListener(NodeSelectedEvent event) {
UITree selected = (UITree) event.getComponent();
TreeNodeImpl<String> selectedNode = (TreeNodeImpl<String>) selected
.getModelTreeNode();
TreeNodeImpl<String> child = new TreeNodeImpl<String>();
child.setData("hello");
selectedNode.addChild(id++, child);
}
public TreeNode<String> getRoot() {
return root;
}
public void setRoot(TreeNode<String> root) {
this.root = root;
