OverviewMap dijit baseLayer

PetarMaletić

Hi,

Is there a way to change baseLayer for OverviewMap dijit. I have multiple basemap layers that are shown or hidden when user select one from my custom basemap gallery...

Thanks.

We handle this in the basic viewer template by doing the following:
1. When a new basemap is selected from the basemap gallery destroy the overview map:

dojo.connect(basemapGallery, "onSelectionChange", function () {
     //close the basemap window when an item is selected
     //destroy and recreate the overview map  - so the basemap layer is modified.
     destroyOverview();
     dijit.byId('basemapBtn').closeDropDown();
   });

2. The destroy overview map function destroys the existing overview map and recreates so its using the new basemap layer:

 function destroyOverview(){
  var ov  = dijit.byId('overviewMap');
  if(ov){
    var vis = ov.visible;
    ov.destroy();
    addOverview(vis);
  }
 }

Here's the code that creates the overview map

function addOverview(isVisible) {
   var overviewMapDijit = new esri.dijit.OverviewMap({
     map: map,
     attachTo: "top-right",
     opacity: 0.5,
     color: "#000000",
     expandfactor: 2,
     maximizeButton: false,
     visible: isVisible,
     id:'overviewMap'
   });
   overviewMapDijit.startup();
 }
