I skipped over your other message. I see now where you tried to
reference an AreaTreeHandler, but that's not necessary.
You sent 2 incomplete pieces of code. The second one looks closer.
Here's a bit of a combination. See if this helps.
[code]
File fileXsl = new File("c:\\xsl.xml");
FileInputStream xslFIS = new FileInputStream(fileXsl);
byte[] xslSource = new byte[xslFIS.available()];
xslFIS.read(xslSource);
xslFIS.close();
ByteArrayInputStream xslBAIS = new ByteArrayInputStream(xslSource);
InputSource xslIS = new InputSource(xslBAIS);
xslSS = new SAXSource(xslIS);
File xmlFile = new File("c:\\xml.xml");
FileInputStream xmlFIS = new FileInputStream(xmlFile);
byte[] xmlSource = new byte[xmlFIS.available()];
xmlFIS.read(xmlSource);
xmlFIS.close();
ByteArrayInputStream xmlBAIS = new ByteArrayInputStream(xmlSource);
InputSource xmlIS = new InputSource(xmlBAIS);
xmlSS = new SAXSource(xmlIS);
FopFactory fopFactory = FopFactory.newInstance();
AWTRenderer renderer = new AWTRenderer(true);
FOUserAgent foUserAgent = fopFactory.newFOUserAgent();
renderer.setUserAgent(foUserAgent);
foUserAgent.setRendererOverride(renderer);
PreviewPanel previewPanel = new PreviewPanel(foUserAgent, null,
renderer);
renderer.setScaleFactor(25.4 * 800 /
(Toolkit.getDefaultToolkit().getScreenResolution() * 210.0));
renderer.setPreviewDialogDisplayed(false);
Fop fop = fopFactory.newFop(MimeConstants.MIME_FOP_AWT_PREVIEW,
foUserAgent);
// Standard fop usage...
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(xslSS);
Result res = new SAXResult(fop.getDefaultHandler());
transformer.transform(xmlSS, res);
// To handle several pages on the same panel :
previewPanel.setDisplayMode(PreviewPanel.CONTINUOUS);
previewPanel.showPage();
previewPanel.setPage(0);
[/code]
That's pretty much how I wrote mine initially, excluding some custom
code like font loading.
The only problem I found with this built in preview panel is the
renderer attached to the PreviewPanel.
1) I'm doing client-server code. Transforms normally run on the server.
The PreviewPanel of course has to run on the client. Changing the zoom
(ScaleFactor) has to re-render the entire document.
2) This also has to create a transformer and renderer object on the
client which is taking a long time.
In my new custom preview panel I'm using the PNGRenderer. This holds
the transformed output in the renderer. I can use it's getNumberOfPages
method to create an array and retrieve the pages with getPageImage. For
the zoom I just use drawImage from Graphics2D which makes the pages a
little fuzzy at any level other than the initial size but they're
readable and it's a lot faster.

HI all i use the PrintPreviewPanel
The problem is that i have to use a AreaTreeHandler but i don't know how
to do it.
The other problem is how to display the toolbar.
Thanks!
