Flexviewer3.4 would like clear result graphic after zoom?

haThach — Wed, 04 Sep 2013 12:16:53 GMT

Hi,

Can anyone point me to the right direction? I am using a regular search widget 3.4, where do I go about clearing the result graphic polygon layer when I hover over the result, click once to zoom to extent, then clear or fade away the result graphic.

ha Thach,

Clicking the little trash can icon clears the graphic and results. There is nothing built in for what you are asking for.

Thanks Robert,

What I really want is able to config the mxml adding a clear graphic function in an area to automatically clear the result graphic after zoom to the extent.

ha Thach,

As I mentioned there is NO configuration for this. You can add this capability to the code if you are working with the source code in Adobe Flash Builder though.

Robert,

Yes, I'm working with the source code in Adobe Flash Builder 4.7, can you point me to a specify area in the source code. Thanks.

ha Thach,

Here is what I would change/Add:

            private function showHighlight(params:Array):void
            {
                var searchResult:ResultItem = params[0];
                var showHighlightPoint:MapPoint = searchResult.center as MapPoint;
                var linkAlias:String = searchResult.attributes.linkAlias;

                popUpRenderer.popUpInfo = configurePopUpInfo(searchResult.attributes);
                popUpRenderer.graphic = searchResult.graphic;

                map.infoWindow.content = popUpRenderer;
                map.infoWindow.contentOwner = popUpRenderer.graphic;
                map.infoWindow.show(showHighlightPoint);
                clearTimeout(hitimer);
                hitimer = setTimeout(clearGraphics, 300);
            }
            
            private function clearGraphics():void
            {
                if (resultFeatureLayer)
                {
                    resultFeatureLayer.featureCollection = new FeatureCollection(new FeatureSet(), resultFeatureLayer.layerDetails); // empty featureset to clear
                }
            }
