org.apache.myfaces.trinidad.component.UIXTreeTable

The Apache Trinidad TreeTable is used to display data that is structured in a hierarchical format. This component displays a hierarchy in a UI similar to a Trinidad Table, and is more elaborate than the Tree component. TreeTable supports displaying columns of data per element in the hierarchy. Unlike the Tree component, TreeTable only supports single rooted hierarchies. The features of the TreeTable component include mechanisms for focusing in on subtrees (within the main tree), as well as expanding and collapsing elements in the hierarchy. Like the Table, the TreeTable's children must be Trinidad Column components. Like the Tree, the TreeTable has a "nodeStamp" facet which renders the "Object Name" Column. The "Object Name" Column contains the primary identifier of an element in the hierarchy. For example, in an organization chart of employees, the "Object Name" Column might be the employee name.

Events:

Type	Phases	Description
`org.apache.myfaces.trinidad.event.RowDisclosureEvent`	Invoke Application	The Expansion event is generated when tree nodes are expanded or collapsed.
`org.apache.myfaces.trinidad.event.SelectionEvent`	Invoke Application	The selection event is delivered when the table selection changes.
`org.apache.myfaces.trinidad.event.FocusEvent`	Invoke Application	Event delivered when user clicks to focus on (or zoom into) a particular element's subtree of children. The TreeTable responds to this event by modifying the "focusPath" property appropriately. Subsequently, any registered FocusListener instances are called.
`org.apache.myfaces.trinidad.event.AttributeChangeEvent`	Apply Request Values	Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.
