org.apache.myfaces.trinidad.component.UIXTree

Apache Trinidad tree components are used to display hierarchical data. For example, if we have a personnel organization chart depicting all the direct reports under each employee, we could use a tree component to display this chart. While each element (employee) in the hierarchy may have any number of child elements, each element can only have one parent element.

The Apache Trinidad tree components use a model to access the data in the underlying hierarchy. The specific model class is org.apache.myfaces.trinidad.model.TreeModel. You may find the org.apache.myfaces.trinidad.model.ChildPropertyTreeModel class useful when constructing a TreeModel.

The tree components use a stamping strategy similar to the Trinidad Table component. Child components are used to display the data for each element in the tree. Each child component is not recreated per element; instead, each child is repeatedly rendered (stamped) once per element. Because of this stamping behavior, only certain types of components are supported as children. Supported components include all components with no behavior and most components that implement the EditableValueHolder or ActionSource interfaces. Each time a child component is stamped, the data for the current element is copied into an EL reachable property. The name of this property is defined by the var property on the tree component. Once the tree has completed rendering, this property is removed (or reverted back to its previous value).

When the user expands or collapses a subtree the tree generates a DisclosureEvent. This event has an isExpanded method that returns whether the user wants to expand or collapse the subtree of a particular element. That particular element is made current on the Tree before the event is delivered.

The Trinidad tree components use an instance of the org.apache.myfaces.trinidad.model.RowKeySet class to keep track of which elements are expanded. This instance is stored as the "expandedRowKeys" attribute on the component. You may use this instance to programmatically control the expand/collapse state of an element in the hierarchy.

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.
