package {
// libraries used by yahoo maps
import com.yahoo.maps.api.YahooMap;
import com.yahoo.maps.api.YahooMapEvent;
import com.yahoo.maps.api.core.location.LatLon;
import flash.display.Sprite;
public class yahoomap extends Sprite {
// creating a Yahoo map object
public var my_yahoo_map:YahooMap = new YahooMap();
// keycode
var key:String=”lHsd5HTV34HrkDmmwIa1P4.upNCGCbAUBoYFRaO0jJYAEgG8LV8ZyygbP6w_x.nBmNPRYwr2Jg–”;
public function yahoomap() {
// adding an event when the map is initialized
my_yahoo_map.addEventListener(YahooMapEvent.MAP_INITIALIZE, on_map_initialized);
// defining how the map should be initialized…
// the parameters represent the keycode and the stage width and hieht
my_yahoo_map.init(key, stage.stageWidth, stage.stageHeight);
// adding pan control
my_yahoo_map.addPanControl();
// adding zoom control
my_yahoo_map.addZoomWidget();
// adding type control (allows you to switch among street, satellite and hybrid)
my_yahoo_map.addTypeWidget();
// adds the scale control
my_yahoo_map.addScaleBar();
// adding the object on stage
this.addChild(my_yahoo_map);
}
private function on_map_initialized(event:YahooMapEvent):void {
// setting the zoom level… it ranges from 1 (closest) to 17
my_yahoo_map.zoomLevel=14;
// setting the latitude and longitude of the map
my_yahoo_map.centerLatLon=new LatLon(20.349230,-74.498468);
}
}
}
