panelBar is used for grouping any content which is loaded on the client side and appears as groups divided on child panels after the header is clicked.

Table 6.335. Component identification parameters
Name | Value |
---|---|
component-type | org.richfaces.PanelBar |
component-class | org.richfaces.component.html.HtmlPanelBar |
component-family | org.richfaces.PanelBar |
renderer-type | org.richfaces.PanelBarRenderer |
tag-class | org.richfaces.taglib.PanelBarTag |
To create the simplest variant on a page use the following syntax:
Example:
...
<rich:panelBar>
<!--//... -->
<rich:panelBarItem label="Canon">
...
</rich:panelBarItem>
<rich:panelBarItem label="Nikon">
...
</rich:panelBarItem>
</rich:panelBar>
...
Example:
import org.richfaces.component.html.HtmlPanelBar;
...
HtmlPanelBar myBar = new HtmlPanelBar();
...
As it was mentioned above, panelBar is used for grouping any content on the client, thus its customization deals only with specification of sizes and styles for rendering.
"width" and "height" (both are 100% on default) attributes stand apart.
Style attributes are described further.
panelBar could contain any number of child panelBarItem components inside, which content is uploaded onto the client and headers are controls to open the corresponding child element.
The "label" attribute is a generic attribute. The "label" attribute provides an association between a component, and the message that the component (indirectly) produced. This attribute defines the parameters of localized error and informational messages that occur as a result of conversion, validation, or other application actions during the request processing lifecycle. With the help of this attribute you can replace the last parameter substitution token shown in the messages. For example, {1} for “DoubleRangeValidator.MAXIMUM”, {2} for “ShortConverter.SHORT”.
For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.
There are two ways to redefine the appearance of all <rich:panelBar> components at once:
Redefine the corresponding skin parameters
Add to your style sheets style classes used by a <rich:panelBar> component
Table 6.336. Skin parameter redefinition for a whole component
Skin parameter | CSS properties |
---|---|
headerBackgroundColor | border-color |
There is one predefined class for the <rich:panelBar> , which is applicable to a whole component, specifying padding, borders, and etc.
Table 6.337. Class name that define a component appearance
Class name | Class description |
---|---|
rich-panelbar | Defines styles for a wrapper <div> element of a component |
Other classes responsible for elements rendering are described for child <rich:panelBarItem> elements and could be found in the components chapters.
Table 6.338. Style component classes
A class attribute | A component element defined by an attribute |
---|---|
styleClass | Applicable to a whole component (together with headers) |
headerClass | Applicable to a header element |
contentClass | Applicable to a content |
In order to redefine styles for all <rich:panelBar> components on a page using CSS, it's enough to create classes with the same names and define necessary properties in them.
To change styles of particular <rich:panelBar> components, define your own style classes in the corresponding <rich:panelBar> attributes.
CSS code piece used on a page:
Example:
...
. rich-panelbar{
padding:10px;
}
.myClass{
font-style:italic;
}
...
When using headerClass and headerClassActive attributes the declaration of headerClass should precede the one of headerClassActive:
Example:
...
.headerClass{
...
}
.headerClassActive{
...
}
...
The component is defined in the following way:
Example:
...
<rich:panelBar contentClass="myClass">
<rich:panelBarItem>
...
</rich:panelBarItem>
</rich:panelBar>
...
Hence, padding for all <rich:panelBar> is changed on a page as well as a font for particular <rich:panelBarItem> content.
Here you can see the example of <rich:panelBar> usage and sources for the given example.
