Insert the Identify Sample into the Index.mxml

ThomasBuchmann1 · ‎03-03-2011

Hello,

I'm trying to add the IdentifySample from the sample applications to my Index.
But where do i have to put the "map"-information from the identifysample?

Here's what i have:

 <esri:Map id="myMap"
     mapClick="mapClickHandler(event)"
     openHandCursorVisible="false">
  <esri:extent>
   <esri:WebMercatorExtent minlon="-120" minlat="30" maxlon="-100" maxlat="50"/>
  </esri:extent>
  <esri:ArcGISTiledMapServiceLayer url="http://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"/>
  <esri:GraphicsLayer graphicProvider="{lastIdentifyResultGraphic}"/>
  <esri:GraphicsLayer id="clickGraphicsLayer"/>
 </esri:Map>

 
 <viewer:ViewerContainer>
  <viewer:configManager>
   <managers:ConfigManager/>
  </viewer:configManager>
  <viewer:dataManager>
   <managers:DataManager/>
  </viewer:dataManager>
  <viewer:mapManager>
   <managers:MapManager/>
  </viewer:mapManager>
  <viewer:uiManager>
   <managers:UIManager/>
  </viewer:uiManager>
  <viewer:widgetManager>
   <managers:WidgetManager/>
  </viewer:widgetManager>
 </viewer:ViewerContainer>

The part above (esri:Map) is from the identifysample, and the other (viewer:xxx) from the index.mxml.

I need your help, please...

Regards,
thombu

Thomas,

I am wondering why you are trying this when there is an identify widget???

ThomasBuchmann1 · ‎03-03-2011

Hi Robert,

because i want an identify Tool that always can be used without activation by use of a widget.
Perhaps you're right and i should try to solve the problem with a widget.

What i want is just a simple Identify Tool like it is in the named sample:
-without a sperate window
- and features are marked after the click

How do i create such a widget? Is it a good idea to try to bring the code from the sample into a widget?

Thanks for your answer,
thomas

Thomas,

Are you interested in just one or two layers or are you wanting to be able to id everything in the map just no interface?

ThomasBuchmann1 · ‎03-03-2011

I want to identify just one or two layers but no interface.
The result should be shown in a "InfoPopUp" as in the IdentifySample.

The ID-Tool must not necessarily always be available. It would also be nice to start it with a Icon.

Thomas,

Seems how your requirements are very specific I would go back to integrating the Identify Sample. You should probably start with this tutorial video http://resources.arcgis.com/gallery/video/arcgis-api-for-flex/details?entryID=870F152C-1422-2418-A01... on how to create a widget. Each widget has access to the map component and you can have widgets that have no UI.

What do you mean? integrating the IdentifySample into the Index.mxml or into a widget?
Thanks for the link. I've already wachted it.
I'm new in Flex so i don't think that i'm able to create a widget from zero.

Is it possible to easily integrate the applications-code into a widget?

thanks for your help!

Thomas,

Going the New Widget route would be best. Yes you could take a majority of the sample code and use that in a widget, but you would be talking about creating a new widget like the video discusses. If you opt against that route than you need to look att adding the identify sample code to the MapManager not the index.mxml.

Thanks for the advice, Robert.
I think i give it up. I have to less knowhow to create this widget.

That's what i've done:

Here it is again, the "esri:map" part. How do i have to change it to run the widget?
