Fade between basemaps

MichaelHoff — Tue, 14 Sep 2010 18:15:47 GMT

I have been able to successfully setup my site with the ability to fade between basemaps by reading through: http://forums.esri.com/Thread.asp?c=158&f=2421&t=286723. Many thanks to all who contributed!!! My question is...how can I get rid of the little box that displays the snap interval values?

Michael,

You can disable data tips by setting the showDataTip property to false.

I read through the thread Michael mentioned too, and was abel to add the fade between basemaps tool to my SFV 1.3 site. I've made a few changes and it works fine.
But there is still one thing annoying me that I haven't solved yet.
When you change the basemap from the map-menu the slider doesn't move. I looked att the function that was changed in the mapmanager (basemapMenuClicked), I guess that's were I want to change the value of the slider. But the slider is added in index.mxml and I don't know how to access it from the function in mapmanger to change it's value.

Another solution would be to just remove the basemaps from the mapMenu, I don't really need them there anyway since I've got the fader tool to control the basemaps. I tried to accomplish this in the config.xml without success. Tried remove them or even move them to another menu, but they still appear in the mapMenu.

Mattias,

Here is some code I used to change the fader in the index from the MapManager. This will not be just copy and paste code for you but you cam see how it is done from this.

//basemap menu clicked
      private function basemapMenuClicked(event:AppEvent):void
      {
       var id:String = event.data as String;
       
       var configBasemaps:Array = configData.configBasemaps;
       var sellabel:String  = configBasemaps[id].label;
       for (var i:Number = 0; i < configBasemaps.length; i++)
       { 
        var label:String  = configBasemaps.label;
        var lyr:Layer = map.getLayer(label);
        if (lyr != null)
        {
         if (configBasemaps.id == id)
         {
          lyr.visible = true;
          if(lyr.id == "Photography"){
           this.parentApplication.fader.value = 0;
           lyr.alpha = 1;
          }else if(lyr.id == "Street Map"){
           this.parentApplication.fader.value = 1;
           lyr.alpha = 1;
          } 
         }
         else
         {
          if(sellabel == "Photography" && lyr.id == "Vector"){
           lyr.visible = true;
           lyr.alpha = 1;
           map.reorderLayer(lyr.id,1000);
          } else {
           lyr.visible = false;
          }
         }
        }
       }
      }

Thank you Robert!

It was the this.parentApplication part before the slider id I needed.
