af:panelTabbed panelTabbed panel tabbed

UIComponent class: oracle.adf.view.rich.component.rich.layout.RichPanelTabbed
Component type: oracle.adf.RichPanelTabbed

The panelTabbed control can be used to display a group of contents that belongs to a showDetailItem. Tab bar(s) with tabs representing the showDetailItem children are displayed. Selecting a tab, displays the associated showDetailItem. If none of the showDetailItem children are selected, the first showDetailItem that is enabled is selected. Typically you would put one or more showDetailItem components inside of the panelTabbed but you may also alternatively place a facetRef, group, iterator, or switcher inside of the panelTabbed as long as these wrappers provide showDetailItem components as a result of their execution.

Geometry Management

There are other ways in which you can control the geometry of this component when it is not being stretched by its ancestor:

Overflow

PanelTabbed is an overflow component. It must be part of a supported layout in order to work properly on the page.

An overflow component requires that it is either:

Under these circumstances, when the overflow component is larger than the parent container, the overflow component will display an overflow button. Selecting the overflow button will show a popup containing the items that didn't fit on the page.

Setting up an overflow component with the following layouts is not supported. If you use one of these layouts, you may have unexpected and inconsistent results:

Code Example(s)

The following is an example of panelTabbed.

<af:panelTabbed id="pt1">
  <af:showDetailItem text="ADF Faces Components" id="sdi1">
    <af:panelHeader text="ADF Faces Components First Child" id="ph1"/>
    <af:panelHeader text="ADF Faces Components Second Child" id="ph2"/>
  </af:showDetailItem>
  <af:showDetailItem text="Architecture" disabled="true" id="sdi2">
    <af:panelHeader text="Architecture First Child" id="ph3"/>
    <af:panelHeader text="Architecture Second Child" id="ph4"/>
  </af:showDetailItem>
  <af:showDetailItem text="Release" id="sdi3">
    <af:panelHeader text="Release First Child" id="ph5"/>
    <af:panelHeader text="Release Second Child" id="ph6"/>
  </af:showDetailItem>
</af:panelTabbed>
   

The following example renders with the tab bar appearing only above the contents.

<af:panelTabbed>
  <af:showDetailItem text="ADF Faces Components" position="above">
    <af:panelHeader text="ADF Faces Components First Child"/>
    <af:panelHeader text="ADF Faces Components Second Child"/>
  </af:showDetailItem>
  <af:showDetailItem text="Architecture">
    <af:panelHeader text="Architecture First Child"/>
    <af:panelHeader text="Architecture Second Child"/>
  </af:showDetailItem>
  <af:showDetailItem text="Release" disabled="true">
    <af:panelHeader text="Release First Child"/>
    <af:panelHeader text="Release Second Child"/>
  </af:showDetailItem>
</af:panelTabbed>
   

Events

Type Phases Description
oracle.adf.view.rich.event.ItemEvent Apply Request Values The itemEvent is triggered when a containing object has an event on one of its child items. For example, a panelTabbed will launch an itemEvent of type 'remove' for one of its child tabs.
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 event 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.rich.component.rich.layout.RichPanelTabbed 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.
childCreation String Yes Valid Values: immediate, lazy, lazyUncached
Default Value: immediate

Controls when the contents of the ShowDetailItem children are created. Introduces a server-side performance enhancement by postponing construction of the components under the undisclosed ShowDetailItems until they are likely to be disclosed Legal values are:
  • "immediate": All showDetailItem children will be populated immediately
  • "lazy": ShowDetailItem children will be populated when they are likely to be disclosed and kept in memory thereafter.
  • "lazyUncached": ShowDetailItem children will be populated when they are likely to be disclosed and may be removed when undisclosed
clientComponent boolean Yes Default Value: false

whether a client-side component will be generated. A component may be generated whether or not this flag is set, but if client Javascript requires the component object, this must be set to true to guarantee the component's presence. Client component objects that are generated today by default may not be present in the future; setting this flag is the only way to guarantee a component's presence, and clients cannot rely on implicit behavior. However, there is a performance cost to setting this flag, so clients should avoid turning on client components unless absolutely necessary.
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, disclosedChild, parent
Default Value: parent

determines how the component will handle geometry management. This specifies where the dimensions of the panelTabbed come from:

  • auto - either "disclosedChild" or "parent", depending on the container the panelTabbed is inside; if the panelTabbed is being stretched by its ancestor then "parent" will be used, otherwise "disclosedChild" will be used
  • disclosedChild - the panelTabbed will get its dimensions from the currently disclosed showDetailItem child (as a result, the stretchChildren attribute on af:showDetailItem and any height assignment on the panelTabbed must be omitted or else it would mean a circular dependency and scrambled display in the browser)
  • parent (the default) - the panelTabbed will get its dimensions from the inlineStyle and if not provided from there then from its parent or if not provided from the parent then from the skin (stretchChildren on af:showDetailItem will be honored)
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 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. Be aware that because of browser CSS precedence rules, CSS rendered on a DOM element takes precedence over external stylesheets like the skin file. Therefore skins will not be able to override what you set on this attribute. 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.
position String Yes Valid Values: above, both, below
Default Value: above

the position of the tab bar. Defaults to "above". In accessibility screen reader mode, tab bar position is always "above".
rendered boolean Yes Default Value: true

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'.
tabRemoval String Yes Valid Values: none, all, allExceptLast
Default Value: none

determines if tab removal is enabled.

This attribute supports these tabRemoval types:

  • none - tab removal is not enabled.
  • all - tab removal is enabled on all tabs, regardless if they are disclosed. The last tab in the panelTabbed can be removed.
  • allExceptLast - tab removal is enabled on all tabs, regardless if they are disclosed. The last tab in the panelTabbed cannot be removed.

Choosing to remove a tab will cause an ItemEvent of type 'remove' to be launched. This event can be listened for on a showDetailItem using the itemListener attribute. It is up to the developer to handle this event and code the actual removal of the tab. This is because of the dynamic nature of the panelTabbed component, which may have dynamic children. This also allows a finer level of control by the developer, who can then choose a custom implementation that may (for example) include warning dialogs, and control of which tab gains focus after a tab is removed.

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. Note that when you are able to set a property on the client, you will be allowed to by using the the .setProperty('attribute', newValue) method, but not the .setXXXAttribute(newValue) method. For example, if you have unsecure="disabled", then on the client you can use the method .setProperty('disabled', false), while the method .setDisabled(false) will not work and will provide a javascript error that setDisabled is not a function.
visible boolean Yes Default Value: true

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
