eSearch widget - combine graphical search, apply buffer, and intersect results

MarkHuffman

My customer wants to be able to select a road segment, apply the buffer, and select the intersecting parcels - all with one click. I have put "applyBuffer();" at the end of queryFeaturesGraphical's onResult function, and placed "intersectResults("esriSpatialRelIntersects");" just before the catch in bufferCompleteHandler. The result is that the intersecting parcels are selected, then all parcels connectd to those parcels are selected then all parcels connected to those are select, and on and on. Any help is appreciated.

Mark,

   Honestly I did not spend the time to run through these changes in the code that you made (your customer not mine). But now I see that the intersectResults is going to call the queryFeaturesGraphical again (as it should). But then you are going to have the applyBuffer at the end and loop through that whole thing again. So you have to limit the applyBuffer to one time through.

So that being said. You need to add a private var to count the number of times thru.

private var xThru:int = 0;

Preferably outside the queryFeaturesGraphical function, and then where you currently have the applyBuffer call change it to this:

                        if(xThru == 0){                             applyBuffer();                             xThru++;                         }

Then you need to clear that private var when you are ready to do the whole operation again (or else you will only be able to do it one time and that's it). So I added this to the clear function:

xThru = 0;
