Hi Javid,
I did initially try to add the red circles to the svg document
programatically, infact I think you emailed me a snippet of your code but
it doesn't work, the code compiles but does not display the red-circles, I
tried to repaint my canvas, that don't work... here's the code I'm using
maybe you might be able to spot where I'm making the error...
//I added this in my constructor
canvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
//The following code I added in my ActionListener triggred by a button
canvas.getUpdateManager().getUpdateRunnableQueue().invokeLater(new
Runnable() {
public void run()
{
SVGDocument doc = canvas.getSVGDocument();
String SVGNS = "http://www.w3.org/2000/svg";;
Iterator i = spots.iterator();
Element g = doc.getElementById("circleGroup");
if (g == null)
{
g = doc.createElementNS(SVGNS,"g");
g.setAttributeNS(null, "id", "circleGroup");
doc.getRootElement().appendChild(g);
}
while (i.hasNext())
{
Point2D pt2d = (Point2D) i.next();
Element e = doc.createElementNS(SVGNS,"circle");
e.setAttributeNS(null,"cx",""+pt2d.getX());
e.setAttributeNS(null,"cy",""+pt2d.getY());
e.setAttributeNS(null,"r","8");
e.setAttributeNS(null,"fill","Red");
g.appendChild(e);
}
}
});
canvas.repaint();
Thx inadvance,
yasmin
