UIComponent class: org.apache.myfaces.trinidad.component.core.output.CoreOutputLabel
Component type: org.apache.myfaces.trinidad.CoreOutputLabel
Component that displays a label for a form component, including a text label, and an (optional) icon indicating the type of message. Developers should use this if they need more control over layout than the built-in label support for label components allows.
<tr:outputLabel value="Name:" for="anInput"/> <tr:inputText id="anInput"/>
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.|
Character used to gain quick access to
the form element specified by the
This attribute is sometimes referred to as the "mnemonic".
|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.|
|converter||javax.faces.convert.Converter||Yes||a converter object|
|for||String||Yes||the ID of the component that this component refers to|
|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.|
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.|
|showRequired||boolean||Yes||whether the associated control displays a visual indication of required user input. If a "required" attribute is also present, both the "required" attribute and the "showRequired" attribute must be false for the visual indication not to be displayed.|
|styleClass||String||Yes||a CSS style class to use for this component.|
|value||Object||Yes||the value of the component. If the EL binding for the "value" points to a bean property with a getter but no setter, and this is an editable component, the component will be rendered in read-only mode.|
|valueAndAccessKey||String||Yes|| An attribute that will simultaneously set both the "value"
and "accessKey" attributes from a single value, using
conventional ampersand ('&') notation.
For example, setting this attribute to "L&abel" will set the label to "Label" and the access key to 'a'.
