UpdateManager thread not refreshing dynamic svg in JSVGCanvas
Hi,
I'm new to batik and to svg. I'm trying to dynamically add elements to
a JSVGCanvas but updates are not been displayed. I went throgh the FAQ
and the mailing list archives( from 200501 to 200703) but I haven't
found a hint to my problem. Does anybody know what am I missing or
mistaking in the code below?
Thanks in advance,
Tacio
PS:
canvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
canvas.setURI( MY_SVG_FILE );
..
// after gvtRenderingCompleted event I'm doing:
canvas.getUpdateManager().getUpdateRunnableQueue()
.invokeLater(
new Runnable() {
public void run() {
SVGDocument doc = canvas.getSVGDocument();
SVGSVGElement root =doc.getRootElement();
String svgNS="http://www.w3.org/2000/svg";
Element rectangle = doc.createElementNS(svgNS, "rect");
rectangle.setAttributeNS(null, "x", "200");
rectangle.setAttributeNS(null, "y", "200" );
rectangle.setAttributeNS(null, "width", "100");
rectangle.setAttributeNS(null, "height", "510");
}

Thanks, it now works! :-) It was my fault. The ancestor had visibility hidden.
cheers,

What does the root element of the document you are loading look
like? Also what element are you appending it to? You aren't setting
any fill/stroke attributes (so it will inherit from it's parent).
It could be a simple matter of the rect being "off screen".
The rect could be a child of an undisplayed element (ancestor
has display="none", visibility="hidden", etc).

Hi,
thanks for the replies, I was indeed forgetting to append rectangle
I've created. But I'm still not getting it displayed though with the
DOM Viewer I can see it was added, any ideas?
thanks,
Tacio

Yup exactly, creating an element does not means adding an element.
So after creating element you still need to add that created element
into some node eg: root node, g node, etc

Hi Tacio,
I don't see any line of code where you are adding the created Element to
your document. Try adding something like this to your code:
root.appendChild(rectangle);
Than it should work, the rest looks ok.
Good luck and have fun
Florian
