Change Search widget to use selectedColor instead of resultMarkerSymbol

ChrisBeaudette

I'm trying to figure out how to modify the Search widget in the Flex Viewer so that selected features (points in my case) are highlighted with the "halo effect" using the selectedColor for the FeatureLayer. The widget currently "highlights" the selected features by overlaying the search icon on top of the point (w/ a slight offset). I want to disable the "icon symbol" in favor of a "highlight symbol".

It looks like to disable the "icon symbol" I can simply comment out this line in displayFeatures():
     graphic.symbol = searchResult.symbol = resultMarkerSymbol

But it's not clear to me how to implement the "highlight symbol".  It seems like I have to capture each selected feature and somehow (?) highlight it.

Thanks in advance for any help.

You could try calling queryLayer.selectFeatures() instead of queryLayer.queryFeatures(). This returns an Array of features though instead of a FeatureSet so you'd also need to make some changes to createSearchResults(). It may be easier to just set the highlight on the Graphic yourself in createSearchResults(). You'd need to add a GlowFilter to the Graphic's filters array.

Here's what's used in the FeatureLayer:

            glowFilter = new GlowFilter();
            glowFilter.alpha = 0.6;
            glowFilter.blurX = 16;
            glowFilter.blurY = 16;
            glowFilter.inner = feature.geometry is Polygon;
            glowFilter.strength = 8;
glowFilter.color = selectionColor;
