Hi there!
I'm wondering about how to use the PreviewPanel correctly.
I tried it like following:
public JComponent getPreviewer() {
if (page == null) {
if(renderer==null){
try {
renderer = newRenderer();
page = new PreviewPanel(agent, null, renderer);
} catch (RenderingException e) {
}
}
}
return page;
}
protected AWTRenderer newRenderer() throws RenderingException {
AWTRenderer renderer = null;
FopFactory fopFactory = AbstractFopRenderer.getFopFactory();
renderer = new AWTRenderer();
agent = fopFactory.newFOUserAgent();
agent.setRendererOverride(renderer);
renderer.setPreviewDialogDisplayed(false);
renderer.setUserAgent(agent);
return renderer;
}
The big question currently is, how to fill the previewer correctly. My
current render method looks as such:
protected void render(Source xml, Source xsl, OutputStream out,
Map parameters) throws RenderingException {
try {
// reset();
Transformer transformer = newTransformer(xsl, parameters);
try {
final Fop fop = getFopFactory().newFop(
MimeConstants.MIME_FOP_PRINT, out);
final Result result = new
SAXResult(fop.getDefaultHandler());
transformer.transform(xml, result);
} catch (FOPException e) {
throw new RenderingException("Couldn't show page", e);
} finally {
out.close();
}
} catch (TransformerException ex) {
throw new RenderingException("Couldn't show page", ex);
} catch (IOException e) {
throw new RenderingException("Couldn't close stream", e);
}
}
What is missing or wrong to get the output from this method into the
previewer?
Kind regards,
Kai
