Examples of HeaderContributor

org.apache.wicket.behavior.HeaderContributor
A {@link org.apache.wicket.behavior.AbstractHeaderContributor} behavior that is specialized onpackage resources. If you use this class, you have to pre-register the resources you want to contribute. A shortcut for common cases is to call {@link #forCss(Class,String)} to contribute apackage css file or {@link #forJavaScript(Class,String)} to contribute a packaged javascriptfile. For instance:
```
 add(HeaderContributor.forCss(MyPanel.class, "mystyle.css")); 
```
