GMap2 - GInfoWindow

[Jeremy Thomerson <je...@wickettraining.com>]

I'm not sure who maintains GMap2 (Martin F?) - but I just created a class
that allows me to show an info window when a GMarker is clicked.  This could
actually be abstracted to allow other calls on a GMarker fairly easily.

Two questions:
1 - is there a better way already built in?  (I couldn't find one)
2 - can you use this class or a better method to include this functionality
in GMap2?

Thanks for the GMap2 contribution!!

public class GInfoWindow extends AbstractBehavior {
 private static final long serialVersionUID = 1L;

 private GMap2 mMap;
 private final IModel<String> mHtmlModel;
 private final GMarker mMarker;

 public GInfoWindow(GMarker marker, String html) {
  mMarker = marker;
  mHtmlModel = new Model<String>(html);
 }

 public GInfoWindow(GMarker marker, IModel<String> html) {
  mMarker = marker;
  mHtmlModel = html;
 }

 @Override
 public void bind(Component<?> component) {
  super.bind(component);

  if ((component instanceof GMap2) == false) {
   throw new IllegalStateException("must be added to a gmap2");
  }
  mMap = (GMap2) component;
 }

 @Override
 public void renderHead(IHeaderResponse response) {
  super.renderHead(response);
  CharSequence html = JavascriptUtils.escapeQuotes(mHtmlModel.getObject());
  String call = "overlays[" + mMarker.getId() + "].bindInfoWindowHtml('" +
html + "', null)";
  response.renderOnDomReadyJavascript(mMap.getJSinvoke(call));
 }
}

It's hard to say what way is better. Look at what we've done in
wicket.contrib.examples.gmap.top.HomePage
I think it pretty much implements the same as what you came up with.
But it does it in an ajax way, clicking a Marker sends an ajax call to 
the server, which generates what has to show up in the Infowindow and 
sends it back.
As I understand your code example the html for the InfoWindow has to be 
known by the time the marker is inserted in the map.
Which might suite your needs.

If you want your code to be preserved for others, come up with a patch 
for wicket-contrib-gmap2-examples.
And if you are desperate you could ask for commit rights on the 
userlist, and do it yourself.

Feel free & have fun,

Martin
