追加された.java
public class SimpleMap implements EntryPoint
{
private MapWidget mapWidget;
// GWT module entry point method.
public void onModuleLoad()
{
final MapOptions options = new MapOptions();
// Zoom level. Required
options.setZoom(8);
// Open a map centered on Cawker City, KS USA. Required
options.setCenter(new LatLng(39.509, -98.434));
// Map type. Required.
options.setMapTypeId(new MapTypeId().getRoadmap());
// Enable maps drag feature. Disabled by default.
options.setDraggable(true);
// Enable and add default navigation control. Disabled by default.
options.setNavigationControl(true);
// Enable and add map type control. Disabled by default.
options.setMapTypeControl(true);
mapWidget = new MapWidget(options);
mapWidget.setSize("800px", "600px");
// Add the map to the HTML host page
RootPanel.get("mapsTutorial").add(mapWidget);
