UIComponent class: org.apache.myfaces.trinidad.component.core.layout.CorePanelHeader
Component type: org.apache.myfaces.trinidad.CorePanelHeader
The panelHeader control places a label and optional icon at the top of a section.
The panelHeader can also be used at the top of an application page to give
the user important messaging information. The types of messages, set by
messageType attribute are:
panelHeader does not support setting the CSS style, but does support setting a size. A large header (H1 in HTML) corresponds to 0, medium to 1, and small to 2. Some render kits and skins support sizes up to 5 (equiv. H6 - HTML's maximum header value) but most renderkits and skins will only support up to 2 (in compliance with the BLAF and BLAF+ specs. Setting the header size to something greater then the supported value will style the header the same as the largest supported value (ie. size="6" will be displayed the same as either a size="5" if supported or a size="2").
panelHeader displaying message information.
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.|
|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.|
||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.|
|icon||String||Yes||the URI for the icon of the header.|
|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.|
info, confirmation, warning, none, error
Set if an error, info, confirmation, or warning header is needed.
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.
Separate multiple triggers with a space. e.g., partialTriggers="cmp1 cmp2"
Identifiers must account for NamingContainers. You can use a single colon to start the search from the root, or use multiple colons to move up through the NamingContainer. For example, "::" will pop out of this component's naming container (it pops out of itself if it is a naming container), ":::" will pop out of two naming containers, etc. The search for the partialTrigger begins from there. e.g., partialTriggers=":::commandButton1" the search begins for the component with id = commandButton1 after popping out of two naming containers relative to this component. To go into naming containers, you separate the naming containers with ':', e.g.,partialTriggers= "nc1:nc2:nc3:componentId".
|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).|
|shortDesc||String||Yes||The short description of the component. This text is commonly used by user agents to display tooltip help text.|
|size||int||Yes||Size of this panelHeader. The largest is 0 and corresponds to an H1 header the smallest is 5 and corresponds to an H6 Header. Note that this version of the tag will display all sizes above 2 the same as size 2. Setting the size to a negative number will allow the header to be calculated according to its parent header. The default value for this property is -1.|
|styleClass||String||Yes||a CSS style class to use for this component.|
|text||String||Yes||the label of the header.|
