The <rich:page> component is used to create basic (X)HTML markup and define document parameters like DOCTYPE, title etc. The component also allows to build top level layout: header, bottom, center and left or right layout areas.
Option to change the renderer of the component (themes support)
Possibility to define parameters of an HTML page
Possibility to create page layout with facets
Provides styling based on RichFaces skinnability
The <rich:page> component together with the <rich:layout> component provides a full-fledged mechanism for markup creation.
First of all, to declare the document type of the page you should use the "markupType" attribute which has the following values:
"html"
"html-transitional"
"xhtml"
"xhtml-transitional"
"html-frameset"
"html-3.2"
The default value is "html".
The "contentType" allows to specify the type of the content and encoding for the page.
The title of the page can be set with the "pageTitle" attribute. To place some other page parameters (like meta information, links to CSS style sheets etc.) in the <head> element of an HTML page use "pageHeader" facet.
Example:
...
<rich:page pageTitle="The title of the page" markupType="xhtml">
<f:facet name="pageHeader">
<meta content="The rich:page component" name="keywords" />
<link rel="shortcut icon" href="/images/favicon.ico" />
<link href="/css/style.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="/js/menu.js"></script>
</f:facet>
<!-- page content -->
</rich:page>
...
Note, the <rich:page> component encodes the full page structure. Therefore, be sure you don't use the doctype declaration, root html element, head and body elements on the same page where you've put this component.
The implementation of the <rich:page> component provides four facets that you can use to arrange the layout of the page: "header", "subheader", "sidebar" and "footer". Their behavior is quite self-explanatory.
The position of the panel rendered by the "sidebar" facet can be set with the "sidebarPosition" attribute that can take either "right" or "left" as values, you can also specify the width for this facet with the "sidebarWidth" attribute.
Example:
...
<rich:page sidebarPosition="left" sidebarWidth="300">
<f:facet name="header">
<!-- header content -->
</f:facet>
<f:facet name="sidebar">
<!-- side panel content -->
</f:facet>
<!-- body content -->
<f:facet name="footer">
<!-- footer content -->
</f:facet>
</rich:page>
...
The <rich:page> component also provides attributes to define CSS classes for each nested facet as well as a body part of the page created with the component.
Several templates are available for the <rich:page> component. A template can be activated with the "theme" attribute.
The theme defines the way the <rich:page> is rendered. Default renderer (default theme) of the <rich:page> has no mappings to skin parameters and just provides CSS classes for the page part. However, the simple theme, which is an extension of the default theme, has mappings to skin parameters and adds the RichFaces skinning for the page elements.
As a whole, RichFaces provides 4 themes for the <rich:page> component out-of-the-box: "simple", "violetRays", "oldschool", "smooth". The Creating a Theme for <rich:page> article tells how you can create your custom theme for the <rich:page> component.
