public class ERXStyleSheet
extends ERXStatelessComponent

Copied from ERExtensions to enable the "title"-attribute for stylesheets. Adds a style sheet to a page. You can either supply a complete URL, a file and framework name or put something in the component content. The content of the component is cached under a "key" binding and then delivered via a direct action, so it doesn't need to get re-rendered too often.

See Also:

Serialized Form

Bindings

filename	name of the style sheet
framework	name of the framework for the style sheet
href	url to the style sheet
key	key to cache the style sheet under when using the component content. Default is the sessionID. That means, you should *really* explicitly set a key, when you use more than one ERXStyleSheet using the component content method within one session
inline	when true, the generated link tag will be appended inline, when false it'll be placed in the head of the page, when unset it will be placed inline for ajax requests and in the head for regular requests

Properties

er.extensions.ERXStyleSheet.xhtml

(defaults true) if false, link tags are not closed, which is compatible with older HTML
