|Oracle Fusion Middleware Tag Reference for Oracle ADF Faces
11g Release 1 (184.108.40.206.0)
UIComponent class: oracle.adf.view.rich.component.rich.layout.RichDecorativeBox
Component type: oracle.adf.RichDecorativeBox
The decorativeBox component can be used to apply a bordered look to its children (i.e. rounded corners). It also supports changing of the rendered theme of its children, so can act as a look and feel transition between areas on a page. For example, a page that has a dark background for its template can use the decorative box to transition to a white background for its main area. This component stretches the child component in the center facet to fill all of available space. It is bordered by eight styled areas that are controlled using skinning keys. The areas listed below are documented in the skinning documentation:
The height of the top area of the component depends on whether or not a component has been put into the top facet. When the facet is set, the topHeight attribute is used to specify the size the content should occupy. Without a component in the top facet, the -tr-height skin property will be used to determine the height. See the skinning keys documentation for more information on the available skinning keys and properties for the decorative box component.
<af:decorativeBox> <f:facet name="center"> <af:outputText value="Here is some content" styleClass="AFInstructionText" /> </f:facet> </af:decorativeBox>
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.|
|center||Content to be stretched in the center of the layout.|
|top||Content to be rendered above the center facet. If present and topHeight not specified, the height will be 50px.|
|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.rich.component.rich.layout.RichDecorativeBox||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.|
|centerLandmark||String||Yes||Valid Values: none, banner, complementary, contentinfo, main, navigation, search
Specifies the WAI-ARIA landmark role for the content of the center facet.
|customizationId||String||Yes||This attribute is deprecated. The 'id' attribute should be used when applying persistent customizations. This attribute will be removed in the next release.|
|dimensionsFrom||String||Yes||Valid Values: auto, children, parent
determines how the component will handle geometry management. This specifies where the dimensions of the decorativeBox come from:
If the oracle.adf.view.rich.geometry.DEFAULT_DIMENSIONS context-param is set to "auto" in the project's web.xml, the default value for this attribute will be "auto". Otherwise, the default value will be "parent".
|id||String||No||the identifier for the component. The identifier must follow a subset of the syntax allowed in HTML:
|inlineStyle||String||Yes||the CSS styles to use for this component. This is intended for basic style changes. The inlineStyle is a set of CSS styles that are applied to the root DOM element of the component. If the inlineStyle's CSS properties do not affect the DOM element you want affected, then you will have to create a skin and use the skinning keys which are meant to target particular DOM elements, like ::label or ::icon-style.|
|partialTriggers||String||Yes||the IDs of the components that should trigger a partial update. This component will listen on the trigger components. If one of the trigger components receives an event that will cause it to update in some way, this component will request to be updated too. Identifiers are relative to the source component (this component), and must account for NamingContainers. If your component is already inside of a naming container, you can use a single colon to start the search from the root of the page, or multiple colons to move up through the NamingContainers - "::" will pop out of the component's naming container (or itself if the component is a naming container) and begin the search from there, ":::" will pop out of two naming containers (including itself if the component is a naming container) and begin the search from there, etc.|
|rendered||boolean||Yes||whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.|
|shortDesc||String||Yes||the short description of the component. This text is commonly used by user agents to display tooltip help text, in which case the behavior for the tooltip is controlled by the user agent, e.g. Firefox 2 truncates long tooltips. For form components, the shortDesc is displayed in a note window. For components that support the helpTopicId attribute it is recommended that helpTopicId is used as it is more flexible and is more accessibility-compliant.|
|styleClass||String||Yes||a CSS style class to use for this component. The style class can be defined in your jspx page or in a skinning CSS file, for example, or you can use one of our public style classes, like 'AFInstructionText'.|
|theme||String||Yes||The component style theme to apply to this component. Themes are cascaded down through all child components. All HTML elements that are rendered by a rich component within a themed component will have the theme added to its list of style classes. Themes are not compatible with tonal styles and therefore only one method can be used per page (themes or tonal styles). A blank theme will remove the current theme, and a value of "inherit", null or not setting a theme will use the current theme. Skins are the sources of the the themes. Some skins may have no themed definitions. Suggested theme names include "dark", "medium", "light", and "default".|
|topHeight||String||Yes||the height of the top facet specified as a CSS length. If dimensionsFrom resolves to "children", percent units are not allowed and the default value is used instead.|
|topLandmark||String||Yes||Valid Values: none, banner, complementary, contentinfo, main, navigation, search
Specifies the WAI-ARIA landmark role for the content of the top facet.
|unsecure||java.util.Set||Yes||A whitespace separated list of attributes whose values ordinarily can be set only on the server, but need to be settable on the client. Currently, this is supported only for the "disabled" attribute.|
|visible||boolean||Yes||the visibility of the component. If it is "false", the component will be hidden on the client. Unlike "rendered", this does not affect the lifecycle on the server - the component may have its bindings executed, etc. - and the visibility of the component can be toggled on and off on the client, or toggled with PPR. When "rendered" is false, the component will not in any way be rendered, and cannot be made visible on the client. In most cases, use the "rendered" property instead of the "visible" property.
Not supported on the following renderkits: org.apache.myfaces.trinidad.core
