<dvt:treemapNode>

dvt:treemapNode treemapNode treemap node

UIComponent class: oracle.adf.view.faces.bi.component.treemap.UITreemapNode
Component type: oracle.dss.adf.treemap.TreemapNode

A child of the Treemap component. The treemap node displays two dimensions of data through its size and color.

Attribute Groups

The <dvt:attributeGroups> tag can be used as a child of this tag. Instead of specifying fillColor or fillPattern directly on this tag, developers can use attributeGroups with type = "color" or "pattern" to have these attributes automatically generated based on categorical bucketing or continuous classification of the data set. If any of these attributes are specified both in this tag and in the attributeGroups type, then the style generated by the attributeGroups will take precedence.

Relationship with other tags

This tag can have the following children:

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.

Supported Facets

Name Description
content advanced node content facet supporting the following ADF components: af:panelGroupLayout, af:spacer, af:outputText, and af:image. Using this facet is only recommended for small data sets and only when the label attribute is not sufficient. Only a single child is supported for layout reasons, so af:panelGroupLayout should be used to wrap multiple child components. Interactivity is not supported for components within this facet.

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.treemap.UITreemapNode Only EL

Specifies a binding reference to store a specific instance of UITreemapNode from a backing bean. Set this attribute only to access code in a backing bean. For example, to reference a treemap node component in the sample managed bean, use the following code: binding="#{sample.treemapNode}"
drilling String Yes Valid Values: off, replace

The drilling behavior for the node. Valid values are:
  • off - (Default) No drilling enabled
  • replace - Drill replace is enabled
