How call stage.stageWidth from class

programming flash
1

Hello to all!

I know this is the total newbie question (and i´m one), but I can´t make it work.

I made a class to create and handle a google map in my swf and everything works very well. But I want to make my layout completely liquid. To acomplish this, I need to call the stage from the class… But it doesn´t seem to be so easy…
I´ve searched everything but still haven´t found how to do it…

the code is bellow:


package classes.gui{

    import flash.geom.Point;
    import flash.display.MovieClip;
    import flash.display.Stage;
    import flash.events.Event;
    import flash.events.MouseEvent;
    import com.google.maps.LatLng;
    import com.google.maps.Map;
    import com.google.maps.MapEvent;
    import com.google.maps.MapType;
    import com.google.maps.MapOptions;
    import com.google.maps.InfoWindowOptions;
    import com.google.maps.MapMouseEvent;
    import com.google.maps.MapMoveEvent;
    import com.google.maps.controls.*;
    import com.google.maps.services.*;
    import com.google.maps.styles.*;
    import com.google.maps.overlays.*;

    public class Gmap extends MovieClip {
        private var zoomRate:Number=1;
        private var dir:Directions;
        public var map:Map = new Map();
        public var stageMC:MovieClip = new MovieClip();
        public var _stage:Stage = stageMC.stage;

        public function Gmap():void {
            this.addChild(stageMC);
            map.addEventListener(MapEvent.MAP_READY, onMapReady);
            map.key="my_original_key_comes_here";
            //the line below works
            //map.setSize(new Point(980, 390));
            
            //the next three lines dont work
            map.width = _stage.stageWidth - 120;
            map.height = (_stage.stageHeight/100) * 60;
            //map.setSize(new Point(stage.stageWidth - 120, (stage.stageHeight/100) * 60));
            
            this.addChild(map);
        }

        // set map properties
        private function onMapReady(event:Event):void {

            
            var bottomRight:ControlPosition=new ControlPosition(ControlPosition.ANCHOR_BOTTOM_RIGHT,16,10);
            var myMapTypeControl:MapTypeControl = new MapTypeControl();
            myMapTypeControl.setControlPosition(bottomRight);
            map.addControl(myMapTypeControl);

            var topLeft:ControlPosition=new ControlPosition(ControlPosition.ANCHOR_TOP_LEFT,16,10);
            var zControl:ZoomControl = new ZoomControl();
            zControl.setControlPosition(topLeft);
            map.addControl(zControl);

            map.setCenter(new LatLng(-15.501119, -47.504229), 12);
            dir = new Directions();
            dir.addEventListener(DirectionsEvent.DIRECTIONS_SUCCESS, onDirLoad);
            dir.addEventListener(DirectionsEvent.DIRECTIONS_FAILURE, onDirFail);
            dir.load("-15.501119, -47.504229 to -15.9814,-47.820805");
            map.addEventListener(MouseEvent.MOUSE_WHEEL, onMouseWheel);
        }

        private function onMouseWheel(e:MouseEvent):void {
            var zoom:Number=map.getZoom();
            if (e.delta>0) {
                map.setZoom(zoom+zoomRate);
            } else {
                map.setZoom(zoom-zoomRate);
            }
        }

        private function onDirFail(event:DirectionsEvent):void {
            trace("****!");
        }

        private function onDirLoad(event:DirectionsEvent):void {
            var dir:Directions=event.directions;

            map.clearOverlays();
            map.addOverlay(dir.createPolyline());
        }

    }
}

any help is more than apreciated!!!
thank´s in forward!
