I just finished more advanced browser/ client capabilities detection.
If anyone wants to take a look at it, I added an example in
wicket-examples called HelloBrowser. It uses Javascript to detect
browser properties, but it has a fallback in case javascript is not
supported (e.g. because of security settings.

Hi,
The wicket:head tag exists for a different reason. You can use it when
you create custom components, such as the datapicker, that use css/
javascript to function. You want to reuse these components on your
pages without having to know what dependencies your page needs. If you
use wicket:head in your component panels, its content will be
'contirbuted' to the current page's head.
I your case, you want to vary the css tag based on some input, right?
That's pretty easy actually. Just add a WebComponent to your page, and
attach an AttributeModifier to it that replaces the href with the
right thing. Like:
html:
link wicket:id=mycss rel=Stylesheet type=text/css
href=styles/main.css/
java:
WebComponent c = new WebComponent(mycss);
IModel model = new Model() {
getObject(Component c) {
if (x) return stylesheetx.css; else return stylesheety.css;
}
}
c.add(new AttributeModifier(href, model);
add(c);
Btw, if you are working on HEAD, there's a basic, user-agent based
browser detection in there, and I am currently finishing some more
advanced browser capabilities detection.

Hello,
I apologise for asking a question that may seem so basic to more
experienced Wicketeers and that has been asked over and over.
I read the docs and searched the archive. Although the topic is indeed
discussed, there was not enough information (or perhaps just not stated
in a way that I could understand) to allow me to figure out what's going
with CSS. Actually, I'm also having a bit of trouble in terms of tags.
My goal is to have a different css page depending on the l10n, client
type, or perhaps other requirements. This is my border:
?xml version=1.0?
html xmlns=http://www.w3.org/1999/xhtml;
xmlns:wicket=http://wicket.sourceforge.net/; xml:lang=en lang=en
wicket:head
titlePage Title/title
link wicket:id=css rel=Stylesheet type=text/css
href=styles/main.css/
script language=javascript type=text/javascript
src=scripts/page.js/script
/wicket:head
body
wicket:border
wicket:body/
/wicket:border
/body
/html
Pretty basic, I think. However, where and how would I make the change
for the CSS. Where and how is the wicket:head tag handled? I suppose
that it is in this handler that link wicked:id= is handled...
In order for me to better understand how tags are handled, could
somebody please point me to the relevant classes, so I can take a look
at the code directly?
If I can, I'll try to add useful info to the wiki.
Thanks so much!
Dave
