Using The Map With A Datadescriptor

Other map settings include the map click handler. A map click handler helps you get the properties of a map click event. Use it, for example, to get the coordinates of the map click. Adding a map click handler:

         // Add map click handler
map.addClickHandler(new MapClickEventHandler() {
    @Override
    public void onClick(final MapClickEvent event) {
    	getUI().showNotification(NotificationType.SUCCESS, "Map clicked", "Longitude: " + event.getLongitude() + ", Latitude: " + event.getLatitude());
    }
});
