打开层GWT绑定

Visit the project home @ http://www.peterfranza.com/projects/gwt-openlayers-bindings/ Adding an Open Layers map bean to your GWT application is as easy as ``` MapWidget map = new MapWidget(true); map.getMap().addLayer(new Google(Google.TYPE.SATELLITE, "World View", false), true); map.getMap().addControl(new NavToolBar()); map.getMap().addControl(new PanZoomBar()); final MarkerLayer ml = new MarkerLayer("Icons"); map.getMap().addLayer(ml, false); map.getMap().setCenter(new LonLat(-98, 40), 5, true, true); map.getMap().addMapListener(new MapIconManager(ml, map)); RootPanel.get().add(map); ```
