Annotation Type StyleSheet

@Retention(value=RUNTIME)
@Target(value=TYPE)
public @interface StyleSheet

If this annotation is present on a ClientConnector class, the framework ensures the referenced style sheets are loaded before the init method for the corresponding client-side connector is invoked.

Absolute URLs including protocol and host are used as is on the client-side. Relative urls are mapped to APP/PUBLISHED/[url] which are by default served from the classpath relative to the class where the annotation is defined.

Special Vaadin urls are also supported. The most useful is vaadin:// which maps to the location of the automatically published VAADIN folder. Using the VAADIN folder and vaadin:// you can publish stylesheets which use images or other files with relative paths.

Example: @StyleSheet( "http://host.com/file1.css", "file2.css")} on the class com.example.MyConnector would load the file http://host.com/file1.css as is and file2.css from /com/example/file2.css on the server's classpath using the ClassLoader that was used to load com.example.MyConnector.
