Re: [Wicket-user] More CSS support in wicket?

Ayodeji Aladejebi Thu, 20 Jul 2006 02:44:46 -0700

some typo errors in previous mail:

In your CSS File (textfield.css):

.textfieldStyle {
background: url(${myImage});
}

In your Wicket Code:
PackageResourceReference imageRes = new PackageResourceReference(MyPanel.class , "image.gif");

CSSSettings css = new CSSSettings( MyPanel.class,"textfield.css");

String imageRefString = urlFor(imageRes);
css.addAttribute(" myImage ",imageRefString );

//and according to igor

add(new StringHeaderContributor(css.getStyle());

or you can do add(new StringHeaderContributor(css.getStyle()); instead of using a label

well it doesnt necessarily have to be like that...anything that reduces stress for developers will always fly in dev space. so may things can be worked out...but i believe that more CSS support is needed in wicket. I am making something that looks like this for my project.

CssMap css = CssMap.parseCSS(MyPanel.class, "style.css");

css.add("bg-image",urlFor(imageReference)); // replaces ${bg-image} with image path

add(new Label("styleHead", css.getStyle());

this works fine for me now though still crappy but suits my work for now.

In general, I doubt that you're going to find much support for that kind of approach. This is because you'd be hard-coding styles into the component, which make them difficult to "skin" later on without changing code.

Please can one regex expert give me the regex for retrieving name from ${name}?

Thanks and for CSS integration, i dream of this:

@CSS (
font-family="Verdana",
[EMAIL PROTECTED]("bg.gif,MyPanel.class")}
)
private class MyPanel extends Panel {

}

will generate this header for the panel:

<style type="text/css">
.[panel_id] {
font-family="Verdana...";
}
</style>

its a dream :)

I can't find it neither in Wicket's API documentation nor in
Wicket Extensions's.  Do you have a link please?
