public class XHTMLPanel extends BasicPanel
JScrollPane. The most common usage is to stuff a URL
into it and then add it to your JFrame. Ex:
import org.xhtmlrenderer.simple.*;
.....
public static void main(String[] args) {
// set up the xhtml panel XHTMLPanel xhtml = new XHTMLPanel();
xhtml.setDocument(new URL("http://myserver.com/page.xhtml"));
JScrollPane scroll = new JScrollPane(xhtml);
JFrame frame = new JFrame("Demo");
frame.getContentPane().add(scroll);
frame.pack();
frame.setSize(500,600);
frame.show();
}
XHTMLPanel renders XHTML and XML which can be loaded as valid Document
instances. You should make sure the document you want to render is well-formed. For XHTML,
there is always a default stylesheet available, even if no CSS is attached to the
XHTML you are loading. For XML, there is no default stylesheet, so you should have
one attached to your XML before trying to render it using the xml-stylesheer processing
instruction. XHTMLPanel has methods to load
documents from a uri (setDocument(String uri)),
from a Document instance (setDocument(Document)) or from an InputStream
(BasicPanel.setDocument(java.io.InputStream,String)).
setFontScalingFactor(float). If you want to make other changes you will
need to get the rendering context (BasicPanel.getSharedContext()) and call methods on
that. Ex:
XHTMLPanel xhtml = new XHTMLPanel();
RenderingContext ctx = xhtml.getRenderingContext();
ctx.setLogging(true); // turn on logging
ctx.setValidating(true); // turn on doctype validation
ctx.addFont(fnt,"Arial"); // redefine a font
ctx.setDomImplementation("com.cooldom.DomImpl");
XHTMLPanel comes with a pre-installed MouseListener which handles :hover events used for rollovers ( @see org.xhtmlrenderer.swing.HoverListener ). XHTMLPanel also comes with a pre-installed LinkListener used to follow links. ( @see org.xhtmlrenderer.swing.LinkListener ) If you want to disable these for some reason you can get the list of mouse listeners and remove them all.

you should not use this unless you have a heavily customized context to
use. To modify just some rendering behavior, consider using

incrementFontSize() and
decrementFontSize()--both scale the font up or down by this
scaling factor. The scaling roughly modifies the font size as a multiplier
or divisor. A scaling factor of 1.2 applied against a font size of 10pt
results in a scaled font of 12pt. The default scaling factor is
