Philippe,
All the SVG handling is done by batik.
I've inserted the JSVGCanvas in the view (still have a flicker problem during drawing,
I think it's because the JSVGCanvas is added to an SWT panel which is also redrawn).
Since this morning I've got the following code working. If this is the correct way to
do things, I then need to know how to get the DOM Node or Element from the Event!
private static final String MOUSE_CLICK= "click";
private static final String MOUSE_MOVE= "mousemove";
private static final String MOUSE_DOWN= "mousedown";
private static final String MOUSE_UP= "mouseup";
private void handleMyEvent(Event event)
{
EventTarget et= event.getTarget();
setTitleText(
" Type = "
+ event.getType()
+ " Phase = "
+ event.getEventPhase()
+ " Current target = "
+ et.getClass()
+ " Timestamp = "
+ event.getTimeStamp());
}
public void createPartControl(final Composite parent)
{
try
{
svgCanvas= new JSVGCanvas(new MyUserAgent(), true, true);
svgCanvas.setDoubleBuffered(true);
svgCanvas.setDoubleBufferedRendering(true);
svgCanvas.addSVGLoadEventDispatcherListener(new SVGLoadEventDispatcherListener()
{
public void svgLoadEventDispatchStarted(SVGLoadEventDispatcherEvent arg0)
{
// setTitleText("svgLoadEventDispatchStarted");
}
public void svgLoadEventDispatchCompleted(SVGLoadEventDispatcherEvent arg0)
{
SVGSVGElement root= svgCanvas.getSVGDocument().getRootElement();
root.addEventListener(MOUSE_CLICK, new EventListener()
{
public void handleEvent(Event arg0)
{
handleMyEvent(arg0);
}
}, true);
root.addEventListener(MOUSE_MOVE, new EventListener()
{
public void handleEvent(Event arg0)
{
handleMyEvent(arg0);
}
}, true);
root.addEventListener(MOUSE_DOWN, new EventListener()
{
public void handleEvent(Event arg0)
{
handleMyEvent(arg0);
}
}, true);
root.addEventListener(MOUSE_UP, new EventListener()
{
public void handleEvent(Event arg0)
{
handleMyEvent(arg0);
}
}, true);
}
public void svgLoadEventDispatchCancelled(SVGLoadEventDispatcherEvent arg0)
{
// setTitleText("svgLoadEventDispatchCancelled");
}
public void svgLoadEventDispatchFailed(SVGLoadEventDispatcherEvent arg0)
{
// setTitleText("svgLoadEventDispatchFailed");
}
});
awtPanel= SWT_AWT.new_Panel(parent);
awtPanel.setLayout(new BorderLayout());
awtPanel.add("Center", svgCanvas);
shell= getViewSite().getShell();
createActions();
} catch (Throwable t)
{
t.printStackTrace();
}
getViewSite().getPage().addSelectionListener(this);
}
Paul.
