Question

I wan to set minimum ans maximum zoom limit for slider in Google Maps , but in Flex Implementation.

Same question is asked here before . But the question as well as answers are for Javascript implementation .

I interpreted in Flex , but got error :

Cannot assign to a method getMinimumResolution on com.google.maps.wrappers.IMapTypeWrapper.

what i did:

var mt:Array = gmap.getMapTypes();

                for (var i:int=0; i<mt.length; i++) {
                    mt[i].getMinimumResolution = function() {return 6;}
                }

how to set it in Flex ?

Answer 1

I have tweaked it a liitle bit and here’s the soln:

gmap.addEventListener(MapZoomEvent.ZOOM_CHANGED, onZoomChanged);

And the Eventlistener :

public function onZoomChanged(e:MapZoomEvent):void 
            {
                var inProcess:Boolean = false;
                if (inProcess) return;

                if (e.zoomLevel > 16) 
                {                   
                    inProcess = true;
                    gmap.setZoom(16);
                    inProcess = false;
                    return
                }
                else if (e.zoomLevel < 13) 
                {                   
                    inProcess = true;
                    gmap.setZoom(13);
                    inProcess = false;
                    return;
                }   }
