Ok, Solved!
I was running that out of the EDT !

Hi,
Sorry again.
I still having some problems.... Let me paste you again this part of
the code:
private JSVGCanvas buildArrow() {
try {
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
URI uri =
this.getClass().getResource("/com/myapp/app/dicomview/player/arrow.svg").toURI();
final SVGDocument doc = (SVGDocument)
f.createDocument(uri.toString());
Element svgRoot = doc.getDocumentElement();
* svgRoot.setAttributeNS(null, "width", String.valueOf(50));*
final JSVGCanvas arrow=new JSVGCanvas();
add(arrow, BorderLayout.EAST);
arrow.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
//arrow.setOpaque(true);
arrow.setVisible(true);
arrow.setSVGDocument(doc);
* arrow.setSize(200,200); //this is a random size!*
arrow.addGVTTreeRendererListener(new
GVTTreeRendererAdapter() {
public void gvtRenderingCompleted(GVTTreeRendererEvent
e) {
System.out.println("Rendering completed!");
System.out.println("size: " + arrow.getSize());
System.out.println("prefSize: " +
arrow.getPreferredSize());
System.out.println("width: " +
arrow.getSVGDocument().getDocumentElement().getAttributeNS(null,
"width"));
System.out.println("x: " +
arrow.getSVGDocument().getDocumentElement().getAttributeNS(null, "y"));
System.out.println("isDynamic: " + arrow.isDynamic());
System.out.println("arrow: " + arrow);
revalidate();
}
});
return arrow;
} catch (Throwable ex) {
ex.printStackTrace(System.out);
ErrorReport.process(ex);
return null;
}
}
Do you see the setSize in bold? it's settings the Canvas to a random
size before it gets rendered. When it gets rendered it will set to 50
(which is what I used in the DOM), the question is, why if I remove
that setSize, my SVG gets rendered in a wrong and moved location
(sometimes)?
Regards!

Hi Ruben,
In general Batik will do that, it's just that you got unlucky. We
don't support trying to change the width and height of the container
after the document is loaded (it's not entirely clear if it's needed
by the SVG spec), if you think about it you should be able to see
that handling changes inside the canvas is quite different from
changes inside the document affecting how the swing component holding
the document is laid out in the swing tree (not to mention that the
swing tree doesn't make it easy to change layout like this).
Changing the color of elements in the document can be done this
way and they will automatically render themselves.

Hi,
Thanks for your response.
I think I got Batik wrong, sorry I'm noob with DOM and Batik. I was
expecting Batik to intercept the events from DOM, so it is aware
when something in the XML changed and render what needed again.
Can't I do that? Then if I want to change, lets say the colour of my
form, what would be the proper way to achieve that? Do I really need
to override all the internal Canvas functions that performs the
render of my object?
Thanks

Hi Ruben,
I think this is really late to be setting the width of the root
SVG element. If you want to go this route you would probably need
to load the XML yourself, update the width and then pass the XML
DOM to the canvas.
Alternately I would suggest overriding setMySize on the
JSVGCanvas so that it ignores the size from the SVG document so
that it is statically sized (well really just respecting the normal
Swing layout rules).

Hello,
I'm in Mac (I read there are some problems in Mac so it might be
actually my problem, but I'd like to confirm that with you guys).
I have a JPanel with a BorderLayout in which I have added on the
EAST area a JSVGCanvas loading a small arrow (originally on the
file is 65px width). I want to load that arrow but resized to 100px.
I simply can't achieve this. When I run my code, the JSVGCanvas
measures 69px width instead of the 100px, and there is nothing on
it, it's just the panel empty with my orange background.
Here is basically what I'm doing:
private void changeWidth(final JSVGCanvas form, final int size) {
Runnable cmd=new Runnable() {
public void run() {
Element svgRoot = form.getSVGDocument().getDocumentElement();
svgRoot.setAttributeNS(null, "width", String.valueOf(size));
}
};
form.getUpdateManager().getUpdateRunnableQueue().invokeLater(cmd);
}
private JSVGCanvas buildArrow() {
try {
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
URI uri =
this.getClass().getResource("/com/myapp/app/dicomview/player/arrow.svg").toURI();
final SVGDocument doc = (SVGDocument)
f.createDocument(uri.toString());
Element svgRoot = doc.getDocumentElement();
final JSVGCanvas arrow=new JSVGCanvas();
arrow.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
arrow.setOpaque(true);
arrow.setVisible(true);
Color inst=new Color(Color.orange.getRed(),
Color.orange.getGreen(), Color.orange.getBlue(), 75);
arrow.setBackground( inst );
arrow.addGVTTreeBuilderListener(new GVTTreeBuilderAdapter() {
@Override
public void gvtBuildCompleted(GVTTreeBuilderEvent e) {
changeWidth(arrow, 100);
}
});
arrow.setSVGDocument(doc);
add(arrow, BorderLayout.EAST);
repaint();
return arrow;
} catch (Throwable ex) {
ex.printStackTrace(System.out);
ErrorReport.process(ex);
returnnull;
}
}
Can anybody please give me a hint in what could be going wrong?
Thanks!
Ruben
