af:panelBox panelBox panel box

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

Unsupported agents: pda

The panelBox is used to place ancillary information on a page, offset by a certain color.

There are four possible attributes to set for the content container. The width of the container can be set to either an exact pixel size or a percentage of the element the content container is within. This is done by using the inlineStyle or styleClass attributes.

Content containers can have header text, icons and a toolbar facet. Set the text and icon attributes to gain these items. The toolbar is a facet that can contain any content within reason (remeber this is a header so don't stick a table in here and think it should look nice!). Most of the time you should be adding simple components like a link, command toolbar button, etc. It is highliy recommended that you use a toolbox with a single toolbar with your specific components inside the toolbar. Doing so allows you to take advantage of the geometry management inside the toolbar and toolbox and gives you automatic access to the overflow capability. If you do not set header text or icon or toolbar facet then the header portion will not render. The content container will only display its children. If you only declare a single one of these (header text or icon or toolbar facet) a header but no the header will show and the content will be offset to line up with the start of the header. If an icon is set, the icon will appear to the left of the header, but the content will still be offset to the left of the header. In addition if you define a toolbar facet then this will always be right aligned to the end of the header. If an icon is set but no header text, the icon will still be displayed on the left but no header text will be visible. If a toolbar facet then this content will be right aligned to the end of the header. NOTE: Anytime the toolbar facet is defined the alignment attribute is ignored. This means setting this value will have no effect.

Content containers can have various color schemes, which can be specified by setting a combination of the ramp and background attributes. The values for the background attribute are default, light, medium, and dark. The default is default. There are two distinct color schemes controlled by the ramp attribute. The value for ramp can be core or highlight with core as the default Please note that changing the background attribute may also change the appearance of the title bar.

You can make changes to the style of the content region of this component by adding your custom styles to the contentStyle attribute.

Content containers will generally have only one child with the actual contents as its children. This child will describe how the content should be displayed. However, the content container can have multiple children, but please note that it does not layout these children in any way.

Events

Type Phases Description
org.apache.myfaces.trinidad.event.DisclosureEvent Apply Request Values,
Invoke Application
The disclosure event is delivered when a node is disclosed.
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.

Supported Facets

Name Description
toolbar Header location for toolbar content. As with JSP pages, when using Facelets, multiple components are not allowed in 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.
background String Yes Valid Values: light, medium, dark, default
Default Value: default

the appearance type of the content container. It should be one of "light", "medium", "dark", or "default"
binding oracle.adf.view.rich.component.rich.layout.RichPanelBox 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.
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.
contentStyle String Yes the inline style of the content region.
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.
disclosed boolean Yes Default Value: true

whether or not to disclose the children
disclosureListener javax.el.MethodExpression Only EL a method reference to a disclosure listener
dontPersist String[] Yes a list of attributes whose changes are NOT to be persisted by FilteredPersistenceChangeManager via the "Persistent Change Manager" registered in adf-config.xml. The token 'ALL' can be used in the list here to indicate that all attribute changes that the component implicitly persists should be excluded. If there is a conflict of values, "dontPersist" always precedes "persist".
handleDisclosure String Yes Valid Values: client, server
Default Value: server

How the disclosure is handled. If client side, the disclosure state of the client component is not propagated to the server until another event triggers a round trip to the server.
Not supported on the following renderkits: org.apache.myfaces.trinidad.core
helpTopicId String Yes the id used to look up a topic in a helpProvider. Note that for this component dynamic help information is shown on the header and will only be shown when the header is shown.
icon String Yes the URI of an image to be displayed in the panelBox header. This attribute supports these various types of URIs:
  • absolute - an absolute path to the image, like "http://oracleimg.com/admin/images/ocom/hp/oralogo_small.gif"
  • relative - a path located relatively to the source page, like "bullet.jpg"
  • context relative - a path relatively based on the web application's context root, like "/images/error.png"
  • server relative - a path relatively based on the web server by application name, like "//adf-richclient-demo-context-root/images/error.png"
As icon does not allow alternative text to be provided for the image, in order to create an accessible product icon must only be used when its use is purely decorative.
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 ('-').
immediate boolean Yes Default Value: false

whether data validation - client-side or server-side - should be skipped when events are generated by this component. When immediate is false (the default), the disclosure event will be delivered during the Invoke Application phase, which will trigger validation. When set to true, the disclosure event will be executed during the Apply Request Values phase.
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.
persist String[] Yes a list of attributes whose changes are to be persisted by FilteredPersistenceChangeManager via the "Persistent Change Manager" registered in adf-config.xml. The token 'ALL' can be used in the list here to indicate that all attribute changes that the component implicitly persists should be included.
ramp String Yes Valid Values: core, highlight
Default Value: core

the appearance type of the content container. It should be either "core" or "highlight"
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.
showDisclosure boolean Yes Default Value: true

Whether or not to render the disclosure icon. If this is set to false all other attributes that deal with disclosure are ignored.
showHeader String Yes Valid Values: never, ifNeeded, always
Default Value: ifNeeded

the display strategy for the panelBox's header. It should be either "never", "ifNeeded", or "always". No header will be shown if the value is "never". If the value is "always", the header will always be shown. This value is useful when the panelBox has a drag source attached or when you want the user to have access to the disclosure control. If the value is "ifNeeded", the header will only be shown if the "icon" or "text" properties are set, if the "toolbar" facet is populated, or if the panelBox has a drag source attached. The default is "ifNeeded" for backwards compatibility
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'.
text String Yes the header text of the panelBox.
titleHalign String Yes Valid Values: start, end, center, left, right
Default Value: start

the alignment of the text and icon within the title bar. Supported values are:
  • "start": left side of the bar in left-to-right mode, right of the bar in right-to-left mode (this is the default)
  • "end": right side of the bar in left-to-right mode, left side of the bar in right-to-left mode
  • "center": in the center
  • "left": left side of the bar
  • "right": right side of the bar
This value is ignored if the toolbar facet is defined.
type String Yes Valid Values: default, flow, stretch
Default Value: default

how the panelBox will handle geometry management. Options are:
  • default - either flow or stretch, depending on the container the panelBox is inside
  • flow - does not support being stretched and will not attempt to stretch the children; the height of the panelBox will be determined by the browser based on the children
  • stretch - supports being stretched and will attempt to stretch the sole child or will wrap the children without stretching them; the height of the panelBox is in no way determined by the children. If helpTopicId is also specified, no instruction text will be displayed when stretched because there would be no space allocated for it.
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
