GraphicsLayer and infoWindowRenderer with events

Jeanlamou — Wed, 13 Jun 2012 16:01:35 GMT

I'm using GraphicsLayer and infoWindowRenderer to display some information on a feature rendered by QueryTask.
It works. However, the user needs to click on the feature to get the information (textual information using TextArea, in LabelDataRenderer, in infoWindowRenderer).

How can I display that information automatically (without user click)? Any sample?

Thanks,

Jean

Have you seen this sample?

I have. The sample uses MouseEvent. However, I would like to display the information automatically (without a mouse event).

Here is the code :

<esri:GraphicsLayer id="myGraphicscityName" graphicProvider="{queryTaskcityName.executeLastResult.features}" >
    <esri:symbol> <esri:SimpleMarkerSymbol id="sms" size="15" color="0xFF0000" style="circle" /></esri:symbol>
    <esri:infoWindowRenderer>
     <fx:Component>
      <esri:LabelDataRenderer >
       <s:TextArea id = "textcityName" text ="The name of the city : {data.cityNamesAct}" width="100" height="75"/>
      </esri:LabelDataRenderer>
     </fx:Component>
    </esri:infoWindowRenderer>

</esri:GraphicsLayer>

The graphic (colored circle) is displayed automatically. But not the LabelDataRenderer with the text (the user has to click on the graphic to display the text).

A lot of samples with symbols, info windows and its renderers (static, dynamic, mouse over/out/click/userthink popups)

How can I display that information automatically (without user click)?

Thanks for the sample. However, what I'm trying to do is to display a dynamic textarea within a graphiclayer. The content of the textarea is the result of a QueryTask.
Within the esri:GraphicsLayer tag, ther is, besides textarea, a static symbol (red circle).
The static symbol is displayed automatically. The textarea is not (user needs to click).

<esri:GraphicsLayer id="myGraphicscityName" graphicProvider="{queryTaskcityName.executeLastResult.features}" >
<esri:symbol> <esri:SimpleMarkerSymbol id="sms" size="15" color="0xFF0000" style="circle" /></esri:symbol>
<esri:infoWindowRenderer>
<fx:Component>
<esri:LabelDataRenderer >
<s:TextArea id = "textcityName" text ="The name of the city : {data.cityNamesAct}" width="100" height="75"/>
</esri:LabelDataRenderer>
</fx:Component>
</esri:infoWindowRenderer>
</esri:GraphicsLayer>
