Properties and All Attributes views

The Properties view for a component shows the most common set of attributes you can set on a component, and, depending on the component, you might also see options for adding controls, actions, or other components. To open the Properties view, click

Window | Show View | Properties.

These common attributes for the Label component display on the h:outputLabel tab in the Properties view. See the All Label attributes table for a complete list of attributes.

The All Attributes view shows a table of all the attributes you can set on a component, which includes those attributes you can access from the Properties view. To switch to the All Attributes view, click the
All Attributes icon in the upper right corner of the Properties view.

Description

accesskey

Not represented

Specifies a single keyboard key as an access key. Pressing the specified access key at runtime gives focus to this component. Pressing ALT plus the specified access key at runtime gives focus to this component (or executes the component if it is a kind of button).

binding

Not represented

An expression that binds the component's instance (usually a user interface component) to a bean property (usually in the backing file).

converter

Not represented

Specifies the data type to which the value is converted. The JavaServer Faces implementation provides a set of Converter implementations that you can use to convert your component data to a type not supported by its renderer.

dir

Not represented

Specifies the component's direction when rendered at runtime. The values can be either:

ltr - left to right

rtl - right to left
If the direction is not specified, a direction appropriate to the encoding of the component is used.

for

Id to label

Specifies the component to which the helper component is to be applied. The value should be the ID of the helped component.

id

ID

Assigns a name to a component. Should be a unique name within a JSP.

lang

Not represented

The language of the component's value(s) and text content. If omitted, the language is inherited from the containing tags (notably the view. Specified as an ISO-standard language abbreviation code. For example, "en" for English, "en-US" for American English, "fr" for French, "de" for German.

Note: This does not "translate" the text in the component, rather, it identifies the language of the component so that operations such as searching, sorting, collating and the like are done correctly.

rendered

Not represented

Can be set to true or false:

false - Component will not be rendered to the browser at runtime.

true - Component will get rendered. This is the default value.

style

Style: Props

Specifies CSS style information for the component (for example, style="font-size : 8pt ; color : red"). Defines the properties (such as font and color) of the selected component. This may be done manually, or by clicking the button and selecting the desired properties from within the window.

styleClass

Style: Classes

Space-separated list of CSS style classes to be applied when this element is rendered. This value must be passed through as the class attribute on generated markup. Defines the classes (such as style sheets) of the selected component. This may be done manually, or by clicking the button and selecting the desired Classes from within the window.

tabindex

Not represented

Specifies the position of the component in the tabbing order in the JSP. This value must be a number between 0 and 32767.

title

Not represented

Specifies the title text, shown in browser as a tooltip at runtime. Used by a browser as the alternative text of a component if the alternative text is not specified.

value

Value

Specifies the initial text value for the component displayed at runtime. Contains information to be displayed, in the form of a specified value or a pointer to a dynamic value.
