Hi

Are there any CSS engine library avaliable?

Such as I have a input HTML:

 Hidden 
 Show 

and a CSS file:

p.hidden { display:none:}

and I can use the engine to render the output as:

Show

Any recommendation?

Thanks.

Swing components will render styled HTML, to an extent..

<sscce>
import javax.swing.*;

class ExampleCSS {

public static void main(String[] args) {
String content =
"<html>" +
"<head>" +
"<style type='text/css'>" +
".hidden { display: none; }" +
".invisible { visibility: hidden; }" +
".red { color: red; }" +
"</style>" +
"</head>" +
"<body>" +
" Hidden " +
" Invisible " +
" I see red " +
"";
JLabel render = new JLabel(content);
JOptionPane.showMessageDialog(null, render);
}
}
</sscce>

Interestingly, neither the display nor visibility
attributes seems to be supported in Java 1.6.

1) Using Swing components. Keep the HTML as
simple as practical, then load it using Java
and remove the invisible elements before passing
it on to a Swing component.

2) The JDIC thing that allows you to 'embed' a
browser in an application.

What version of CSS is Java Swing supporting?

I hope it can be supporting full CSS 2.0, e.g.

DIV > P:first-child { display: none }

Also, priority of styles is important, e.g.

p {display: hidden; }
#test {display: block; }

if my paragraph is with ID = test, then it should not be hidden...

Therefore, I am looking for fully functional CSS engine.

Not enough. Swing's support for CSS is very low.
I am not sure of the spec. it claims to support,
but even then I am pretty sure it makes no
guarantees about supporting all of it.

Roedy could probably tell you some funny stories
about Swing's rendering of HTML as well.

BTW - a better way to post than 'bottom-posting'*
is to post 'in-line with trimming'. Using ILWT
you trim anything not immediately relevant to
the reply (including signatures) and reply
directly after each comment of interest.

* Which, BTW, is still preferable to 'top-posting'.

Did you look at the link I gave you:

http://mindprod.com/jgloss/htmlrendering.html

Several of those rendering packages handle css.

You are rendering HTML with CSS styles, not rendering CSS.

I found that by typing "Java gecko" into Google and pressing the Search
button. I guess this might be hard if you don't happen to know that
Mozilla's layout-engine component is called Gecko.

After looking at that project more carefully myself, it looks like the
last update was in 2005. That's not a good sign. You should do some
searching on your own ("Java gecko") but here's one that looks more up
to date:
