Hi Mili,
Are you asking about how to listen for the map's zoom event? If so,
you should know there are multiple zoom-related events you can listen
for. The Google Maps API has a MapZoomEvent object with several event
names. I listen for the "ZOOM_CHANGED" event in my code which looks
like this:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx = "http://www.adobe.com/2006/mxml";
xmlns:maps = "com.google.maps.*"
layout="absolute">
<mx:Script>
<![CDATA[
import com.google.maps.controls.ControlPosition;
import com.google.maps.controls.NavigationControl;
import
com.google.maps.controls.NavigationControlOptions;
import com.google.maps.LatLng;
import com.google.maps.MapOptions;
import com.google.maps.MapType;
import com.google.maps.MapZoomEvent; // Import the
MapZoomEvent
import mx.controls.Alert;
private const MAP_API_KEY:String =
YOUR_API_KEY_HERE;
private const MAP_CENTER:LatLng = new LatLng(0, 0);
private function onMapPreinitialize(evt:Event):void {
this.map.setInitOptions(new MapOptions({
zoom: 1,
center:MAP_CENTER,
mapType: MapType.NORMAL_MAP_TYPE,
mapTypes: [MapType.NORMAL_MAP_TYPE]}));
}
private function onMapReady(evt:Event):void {
// Zoom Event Listener
map.addEventListener(MapZoomEvent.ZOOM_CHANGED,
onMapZoomChanged,
false, 0, true);
// Navigation Control
var
navigationControlOptions:NavigationControlOptions =
new
NavigationControlOptions({position: new ControlPosition
(ControlPosition.ANCHOR_TOP_RIGHT, 4, 60)});
map.addControl(new
NavigationControl(navigationControlOptions));
}
private function
onMapZoomChanged(evt:MapZoomEvent):void {
Alert.show("ZOOMED to level " +
map.getZoom().toString());
}
]]>
</mx:Script>
<maps:Map id="map" key="{MAP_API_KEY}"
mapevent_mapready = "onMapReady(event)"
mapevent_mappreinitialize = "onMapPreinitialize(event)"
width="100%" height="100%"/>
</mx:Application>
