A question for Igor

[Matthew Young]

I am looking at the wicket.markup.html.tabs.TabbedPanel
(wicket-extensions)<http://wicketstuff.org/wicket13/compref/?wicket:bookmarkablePage=%3Aorg.apache.wicket.examples.compref.TabbedPanelPage>example
on
http://wicketstuff.org/wicket13/compref/, I couldn't figure out how you
switch the css.  Is that done in WicketExamplePage?  Unfortunately,
WicketExamplePage.java is not part of the source.
