Hi Thomas,
This is the code for my CircleAction,
public class CircleAction implements EventListener
{
public void handleEvent(Event evt)
{
Element elt = (Element) evt.getCurrentTarget();
if (evt.getType() == "click")
{
elt.setAttributeNS(SVG_NS, "fill", "yellow");
}
}
}
The evt.getCurrentTarget() is not recognised?
Thx
yasmin
