Above example is really helpfull. I am sending my own piece of code so that it can also help others to develop Google Map V3 with GWT 2.4
Jars Require for Google Map V3 is gwt-maps.jar (Version 3.8.0). For Maven build below is the dependency:
com.google.gwt.google-apis gwt-maps 3.8.0 In your entryPoint.gwt.xml write down the below:
Import statements are:
import com.google.maps.gwt.client.MapOptions; import com.google.maps.gwt.client.LatLng; import com.google.maps.gwt.client.MapTypeId; import com.google.maps.gwt.client.GoogleMap;In GWT code take a button and write down the map loading code in to buttons onClick Event.
// This is the layout which will hold the button final HLayout actionbuttonsLayout = new HLayout(10); final IButton showMap = new IButton("Locate your Store"); actionbuttonsLayout.addMember(showMap); //--- This is the layout which will hold the Map final HLayout mapLayout = new HLayout(50); final SimplePanel widg = new SimplePanel() ; widg.setSize("700px", "200px"); layout.addMember(mapLayout); mapLayout.setVisible(false); // This is the Click Handler where the map rendering process has been written showMap.addClickHandler(new ClickHandler() { public void onClick(ClickEvent event) { MapOptions options = MapOptions.create(); options.setCenter(LatLng.create(39.509, -98.434)); options.setZoom(6); options.setMapTypeId(MapTypeId.ROADMAP); options.setDraggable(true); options.setMapTypeControl(true); options.setScaleControl(true); options.setScrollwheel(true); GoogleMap theMap = GoogleMap.create(widg.getElement(), options) ; mapLayout.addMember(widg); mapLayout.setVisible(true); } });
