Hi,
I have written a Swing component which wraps JSVGCanvas, and I would
like to capture DOM mouse click events so that I can draw on the canvas
where the user has clicked. So I register and define my event listener
like this:
public class PlanViewPanel extends JPanel implements MouseWheelListener,
EventListener, SVGLoadEventDispatcherListener {
....... stuff ......
public PlanViewPanel(SVGDocument svg) {
svgCanvas.setDocument(svg);
svgCanvas.addMouseWheelListener(this); // this is for
something else entirely
scrollPane = new JSVGScrollPane(svgCanvas);
scrollPane.setScrollbarsAlwaysVisible(true);
scrollPane.setPreferredSize(Toolkit.getDefaultToolkit().getScreenSize());
add(scrollPane);
setMinimumSize(new Dimension(800,600));
svgCanvas.getSVGDocument().getRootElement().addEventListener("click",
this, false);
}
.... stuff ....
public void handleEvent(org.w3c.dom.events.Event evt) {
System.out.println("did something");
}
}
but my event handler is never called (I've placed a breakpoint and run
it in the eclipse debugger to confirm this). I have confirmed also
using a debugger that the event handler is present in the hashtable in
the document root's EventSupport structure, but I do not understand why
it is not called. I have messed around with various different event
types and tried bubble/capture, but nothing works.
Using JDK 1.6.0 and Batik 1.7.
Any suggestions would be greatly appreciated.
Matthew Wilson.
