Rich Tree - Hyperlink to the leaf nodes
sincanvin Nov 4, 2011 10:36 AMHi,
I am using rich:tree to create a tree and I want to attach hyperlink to the leaf nodes. Can some one suggesst how to do this?
Thanks,
xhtml -
<rich:tree switchType="client" nodeSelectListener="#{simpleTreeBean.processSelection}" value="#{simpleTreeBean.treeNode}" var="item"/>
Java Code -
public class SimpleTreeBean {
private TreeNode rootNode = null;
private List<String> selectedNodeChildren = new ArrayList<String>();
private String nodeTitle;
private static final String DATA_PATH = "/Pages/data.properties";
private void addNodes(String path, TreeNode node, Properties properties) {
boolean end = false;
int counter = 1;
while (!end) {
String key = path != null ? path + '.' + counter : String.valueOf(counter);
String value = properties.getProperty(key);
if (value != null) {
TreeNodeImpl nodeImpl = new TreeNodeImpl();
nodeImpl.setData(value);
System.out.println("Data..."+nodeImpl.getData());
node.addChild(new Integer(counter), nodeImpl);
addNodes(key, nodeImpl, properties);
counter++;
} else {
end = true;
}
}
}
private void loadTree() {
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
InputStream dataStream = externalContext.getResourceAsStream(DATA_PATH);
try {
Properties properties = new Properties();
properties.load(dataStream);
rootNode = new TreeNodeImpl();
addNodes(null, rootNode, properties);
System.out.println("Title..."+rootNode.isLeaf());
} catch (IOException e) {
throw new FacesException(e.getMessage(), e);
} finally {
if (dataStream != null) {
try {
dataStream.close();
} catch (IOException e) {
externalContext.log(e.getMessage(), e);
}
}
}
}
public void processSelection(NodeSelectedEvent event) {
HtmlTree tree = (HtmlTree) event.getComponent();
nodeTitle = (String) tree.getRowData();
selectedNodeChildren.clear();
TreeNode currentNode = tree.getModelTreeNode(tree.getRowKey());
if (currentNode.isLeaf()){
selectedNodeChildren.add((String)currentNode.getData());
}else
{
Iterator<Map.Entry<Object, TreeNode>> it = currentNode.getChildren();
while (it!=null &&it.hasNext()) {
Map.Entry<Object, TreeNode> entry = it.next();
selectedNodeChildren.add(entry.getValue().getData().toString());
}
}
}
public TreeNode getTreeNode() {
if (rootNode == null) {
loadTree();
}
return rootNode;
}
public String getNodeTitle() {
return nodeTitle;
}
public void setNodeTitle(String nodeTitle) {
this.nodeTitle = nodeTitle;
}
}
