Hi Pamela,
thanks a lot for Your input.
I want to make function that creates polygon and return its reference.
Below is the function. I believe that key is in the addEventListener
function. If I could get this function to return polygon then I could
use this polygon for return object for makePolygonFromXML. In the code
below I put polygon=polygonLoader.addEventListener(Event.COMPLETE,
function(event:Event):Polygon which doesn't work How do I make this
function to return polygon reference?
I tried to separate loader function (function that creates array of
points) from function that creates polygon, but the problem is the
same. addEventListener function must return array of points in order
to use in function that creates polygon and I don't know how to make
this function to return anything.
Tnx.
Goran
private function
makePolygonFromXML(ID:String,name:String,xmlFile:String,col:Number,al:Number,wid:Number):Polygon
{
var polygonLoader:URLLoader
polygonLoader = new URLLoader()
var polygon:Polygon
polygon=polygonLoader.addEventListener(Event.COMPLETE,
function(event:Event):Polygon {
var xmlCont:XML=new XML(polygonLoader.data);
var points:Array = new Array;
for each (var location:XML in xmlCont..*)
{
var LLfromXML:LatLng = new
LatLng([EMAIL PROTECTED],
[EMAIL PROTECTED]);
points.push (LLfromXML)
}
var polygonOptions:PolygonOptions= new
PolygonOptions
var fillStyle:FillStyle = new FillStyle;
fillStyle.alpha = al;
fillStyle.color = col;
polygonOptions.fillStyle = fillStyle;
polygonOptions.tooltip="<font size='17'>" +
name + "</font>\n<font
size='9' color='#726e00'>Kliknite za više podataka</font>"
var strokeStyle:StrokeStyle = new StrokeStyle;
strokeStyle.thickness=wid
strokeStyle.color = 0x000000;
strokeStyle.alpha=1
polygonOptions.strokeStyle = strokeStyle
var polygon:Polygon = new Polygon (points,
polygonOptions)
polygon.addEventListener(MapMouseEvent.CLICK,
function(e:MapMouseEvent):void
{
navigateToURL(new
URLRequest("http://someurl"; + ID),'_self')
})
gMap.addOverlay(polygon);
})
var request:URLRequest=new URLRequest(xmlFile)
try
{
polygonLoader.load(request);
}
catch(error:Error)
{
}
return polygon
}
