Multiple Graphics Layers?

WesBailes — Tue, 16 Nov 2010 19:29:02 GMT

Can multiple graphics layers be implemented? Basically I have a search where the geometry result is a polygon that I want to highlight, but also show an infoSymbol pointing to the polygon's label point. Seems like that only 1 or the other will work. Any suggestions on how to work around this are welcomed. Code is:

var graphic1:Graphic = featureSet.features[0];
var graphic2:Graphic=featureSet.features[0];
var polygon: Polygon;
var centerPt: MapPoint;
polygon = graphic2.geometry as Polygon;
centerPt = polygon.extent.center;
graphicsLayer2.add(graphic2); //the graphics layer with a simple fill symbol set (polygon geometry)
graphic1.geometry = centerPt;
graphicsLayer1.add(graphic1); //the graphics layer with a infoSymbol set (point geometry)

This looks good. Double-check the order of the layers.

Got it to work...instead of both graphics (polygon and point) originally referencing featureSet.features[0];, I created a new graphic for the polygon (which didn't need attributes). I also added these to one graphics layer. Working code is below:

var graphic1:Graphic = featureSet.features[0];
var polygon: Polygon;
var centerPt: MapPoint;
polygon = graphic1.geometry as Polygon;
centerPt = polygon.extent.center;
graphic1.geometry=centerPt;
graphic1.symbol=myInfoSymbol;
var graphic2:Graphic=new Graphic(polygon,myFillSymbol);
graphicsLayer.add(graphic2);
graphicsLayer.add(graphic1);
