Tooltip on a Flared Cluster

JoshObrecht — Thu, 07 Apr 2011 12:20:50 GMT

I was wondering if anyone has been able to achieve this yet. I have a Feature Layer using a Weighted Cluster. I have been able to set the the Tooltip for the flared graphic, however it will not show. Any help would be wonderful.

I haven't worked with clustering but Mansour wrote a post about extending the flare symbol class that might be of some use to you.

I have seen that and it doesn't help as it pertains to getting tooltips to show on the flared elements.

Josh,

What do you want a tooltip to show on? Are you trying to get a tooltip on the main graphic? This would be the graphic that is showing the count...

Please let me know.

I want the tooltips on the smaller elements that show after it flares.

I assume that there is an easier way than this; however, I did not have much luck. So, you can create a custom tooltip and use it. Just listen for your roll over/roll out and it will display.

Using the sample code from the flex api samples page you can add this:

   import mx.controls.ToolTip;  
                                import mx.managers.ToolTipManager;
   
   private  var customToolTip:ToolTip;
   
   protected function map_loadHandler(event:MapEvent):void
   {
    //map.addEventListener(FlareMouseEvent.FLARE_CLICK, flareClickHandler);    
    map.addEventListener(FlareEvent.FLARE_IN_START, flareInStartHandler);    
    addEventListener(FlareMouseEvent.FLARE_OUT, rollOutHandler);
    map.addEventListener(FlareMouseEvent.FLARE_OVER, rollOverHandler);
    
   }
   private function showCustomToolTip(gr:Graphic, stagex:Number, stagey:Number):void
   {
    customToolTip = ToolTipManager.createToolTip(gr.attributes.CITY_NAME,stagex,stagey) as ToolTip;
    
   }
   protected function rollOverHandler(event:FlareMouseEvent):void
   {
    removeEventListener(FlareMouseEvent.FLARE_OVER, rollOverHandler);
    showCustomToolTip(event.graphic, event.stageX, event.stageY);
    
   }
   protected function rollOutHandler(event:FlareMouseEvent):void
   {   
    ToolTipManager.destroyToolTip(customToolTip); 
   }

You will need to play around with the listeners if you want a roll over and click, but this might get you moving in the right direction.

Great! That does exactly what I need.
