Examples of com.google.gwt.maps.client.MapType

com.google.gwt.maps.client.MapType
A MapType is a sequence of tile layers, a map projection, a tile size, and assorted other settings, link colors, and copyrights. There are three predefine map types: {@link MapType#normalMap}, {@link MapType#satelliteMap}, and {@link MapType#hybridMap}. You can create instances of this class to define custom map types. In order to show them on the map, use the {@link MapWidget#addMapType(MapType)}method. You can use {@link com.google.gwt.maps.client.overlay.TileLayerOverlay TileLayerOverlay}to add to (rather than entirely replace) the map's tile layers. @see MapWidget#addMapType(MapType) @see com.google.gwt.maps.client.overlay.TileLayerOverlay

        TileLayer tileLayer = initTileLayer();
        MapWidget map = new MapWidget();
        map.setSize("300px", "300px");
        Projection projection = new MercatorProjection(20);
        assertNotNull("new MercatorProjection(20)", projection);
        MapType mapType = new MapType(new TileLayer[] {tileLayer}, projection,
            "MyMap");
        map.addMapType(mapType);
        RootPanel.get().add(map);
        map.setZoomLevel(10);
        map.setCurrentMapType(mapType);
