componentUI + JSVGCanvas

[sophia <ja...@freenet.de>]

Hi,

I'm trying to convert swing components to svg using SwingSVGPrettyPrint. For
most components it works fine but 
when I try to convert a JSVGCanvas object (most of the time) I get the
following error:

UIDefaults.getUI() failed: no ComponentUI class for:
org.apache.batik.swing.JSVGCanvas

the code is:


//this is needed to get all components visible (e.g. if swing is a
JSplitPane object or any other object which 
//contains JComponent object) 
//this method might be part of the error because sometimes when i don't use
this method and start directly
//to convert, the whole thing works (but sometimes not....). so any ideas
about getting all components visible 
//wihtout using this method are welcome   
private static final void packIt(JComponent swing) {
  JFrame frame = new JFrame();
  frame.add(swing);
  frame.pack();
}
	
public static final void convert(JComponent swing, OutputStream out) {
  DOMImplementation domImpl =
GenericDOMImplementation.getDOMImplementation();
		
  org.w3c.dom.Document document =
domImpl.createDocument("http://www.w3.org/2000/svg", "svg:svg", null);

  SVGGeneratorContext ctx = SVGGeneratorContext.createDefault(document);

  SVGGraphics2D svgGenerator = new SVGGraphics2D(ctx, false);
         
  packIt(swing);
         
  SwingSVGPrettyPrint.print(swing, svgGenerator);
  
  ...      



Thanks for any advice
