<dvt:node>

dvt:node node node

UIComponent class: oracle.adf.view.faces.bi.component.hierarchyViewer.Node
Component type: oracle.dss.adf.hierarchyViewer.Node

The node component is used to stamp out nodes in the hierarchy.

The "zoom100", "zoom75", "zoom50", and "zoom25" facets are used to specify the stamps for different zoom levels of the hierarchy. The "zoom100" facet is typically the most detailed, showing the most information, because the nodes are larger at 100% size. The "zoom25" facet is typically the least detailed, showing the least information, because the nodes are smaller at 25% size.

Relationship with other tags

This component must be a child of the hierarchyViewer component.

The node component can have the following children: facet.

Events

Type Phases Description
org.apache.myfaces.trinidad.event.AttributeChangeEvent Invoke Application,
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.

Attributes

Name Type Supports EL? Description
attributeChangeListener javax.el.MethodExpression Only EL a method reference to an attribute change listener. 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.
binding oracle.adf.view.faces.bi.component.<wbr/>hierarchyViewer.Node Only EL an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.
facetName String Yes
height int Yes Specifies the height of the node, in pixels, at full size
id String No the identifier for the component. The identifier must follow a subset of the syntax allowed in HTML:
  • Must not be a zero-length String.
  • First character must be an ASCII letter (A-Za-z) or an underscore ('_').
  • Subsequent characters must be an ASCII letter or digit (A-Za-z0-9), an underscore ('_'), or a dash ('-').
inlineStyle String Yes The inline style of the hierarchy viewer node. Can be used to control the colors/fonts of the hierarchy viewer node.
rendered boolean Yes Specifies whether the component is rendered. This is used in conjunction with the type attribute to determine which node template to stamp out for a given data element. The first node component whose type matches that of the data element will be stamped for that data element. If no type matches, then the first node whose rendered attributes evaluates to true will be stamped for that data element.
setAnchorListener String Yes a method reference to a set anchor action listener, the method is invoked when the end user marks a node as the new anchor of the HierarchyViewer, normally via a double-click mouse action
shape String Yes

Specifies the shape of the node. Valid values are:

  • "rect" - rectangular
  • "roundedRect" - rectangular with rounded corners
  • "ellipse" - elliptical
showExpandChildren boolean Yes Specifies whether the Expand Children action is rendered
showIsolate boolean Yes Specifies whether the Isolate action is rendered
showNavigateUp boolean Yes Specifies whether the Navigate Up action is rendered.
styleClass String Yes Sets a CSS style class to use for this component.
type String Yes Specifies the types of nodes this stamp should be used for. This is used in conjunction with the rendered attribute to determine which node template to stamp out for a given data element. The first node component whose type matches that of the data element will be stamped for that data element. If no type matches, then the first node whose rendered attributes evaluates to true will be stamped for that data element.
width int Yes Specifies the width of the node, in pixels, at full size
