Link Standalone Identify funtion to button

MikeJun — Wed, 15 Dec 2010 18:18:40 GMT

Hi,

I just want to fire identify function, downloaded from sample code at http://resources.esri.com/help/9.3/arcgisserver/apis/flex/samples/index.html, from a button.

When I hook up this to button like <mx:Button toolTip="Identify" click="mapClickHandler(event)" /> I got error message like "1118: Implicit coercion of a value with static type flash.events:MouseEvent to a possibly unrelated type com.esri.ags.events:MapMouseEvent."

Any help appreciated!

Mike,

You need to do something like this:

<mx:Button toolTip="Identify" click="{myMap.addEventListener(MapMouseEvent.MAP_CLICK, mapClickHandler)}" />
<esri:Map id="myMap"
              openHandCursorVisible="false">

Robert! Thank you for the quick response! It works great!

One thing after another! What I try to do is make a simple toolbar including zoom in, out, pan, next, full view with identify tool. When I put these zoom tools that I got from sample code and identify tool together, I can't scroll the attribute table after using one of these zoom tool. It just do pan function.

I think what I need is to clear any zoom tools funcation selected previous before firing up identify tool.

I figured it out! Thanks!

private function mapClickHandler(event:MapMouseEvent):void
{

navToolbar.deactivate();

Mike,

You need to do something like this:

<mx:Button toolTip="Identify" click="{myMap.addEventListener(MapMouseEvent.MAP_CLICK, mapClickHandler)}" />
<esri:Map id="myMap"
              openHandCursorVisible="false">

Thank you Robert for this reply as well, it helped me too.
