public class TreeNode
extends org.apache.struts2.components.ClosingUIBean

Renders a tree node within a tree widget with AJAX support.

Either of the following combinations should be used depending on if the tree is to be constructed dynamically or statically.

Dynamically:

• id - id of this tree node
• title - label to be displayed for this tree node

Statically:

• rootNode - the parent node of which this tree is derived from
• nodeIdProperty - property to obtained this current tree node's id
• nodeTitleProperty - property to obtained this current tree node's title
• childCollectionProperty - property that returnds this current tree node's children

Examples

 

 <-- Creating tree statically using hard-coded data. -->
 <s:tree id="..." label="...">
    <s:treenode id="..." label="..." />
    <s:treenode id="..." label="...">
        <s:treenode id="..." label="..." />
        <s:treenode id="..." label="..." />
    </s:treenode>
    <s:treenode id="..." label="..." />
 </s:tree>

 <-- Creating tree dynamically using data from backing action. -->
 <s:tree
          id="..."
          rootNode="..."
          nodeIdProperty="..."
          nodeTitleProperty="..."
          childCollectionProperty="..." />
