Re: GMap2 and zoom_changed

[dleeper]

This is what I am currently doing.

zoomChangedListener = new ZoomChangedListener();
add(zoomChangedListener);

map.add(new HeaderContributor(new IHeaderContributor() {
private static final long serialVersionUID = 1L;

public void renderHead(IHeaderResponse response) {

response.renderOnDomReadyJavascript(zoomChangedListener.getJSinit().toString());
}
}));

public class ZoomChangedListener extends AbstractDefaultAjaxBehavior
{
private static final long serialVersionUID = 1L;

@Override
protected void respond(AjaxRequestTarget target)
{
Request request = RequestCycle.get().getRequest();

String zoom = request.getParameter("zoom");

System.out.println( "NEW ZOOM: " + zoom );

}

public Object getJSinit()
{
return map.getJSinvoke("addListener('zoom_changed', '" +
this.getCallbackUrl()
+ "')");
}
}

Unfortunately the respond is not being called.  Not sure why.

GMap2 and zoom_changed

[Doug Leeper]

I was under the impression that when the GMap2 zoomed in/out, the Wicket GMap2 
object would be updated.   When I query Wicket GMap2 upon a dblclick after I 
had zoomed in, the zoom level had not changed.

Should this be the case?

If not, I would like to be able to add a zoom_changed listener on the GMap2 in 
my app.  What is the best way to do so?  Does anyone have any examples?

Thanks in advance,

 - Doug
