Answer 1

dispatching the event and setting the "prog" var to the % in
which i want my meter to display
//heres the flex side
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="
http://www.adobe.com/2006/mxml"
horizontalScrollPolicy="off" verticalScrollPolicy="off"
backgroundColor="#000000" width="100%" height="100%">
<mx:Metadata>
[Event(name="setMeter", type="flash.events.Event")]
</mx:Metadata>
<mx:Script>
<![CDATA[
public function populate(mySize:Number):void
prog=mySize * 10;
dispatchEvent(new Event("setMeter", true));
]]>
</mx:Script>
<mx:SWFLoader source="meter.swf" width="100%"
height="100%" id="mtr1"/>
<mx:Number id="prog"/>
</mx:Canvas>
what im doing here is adding an event listener from my
embedded swf (4 parents deep).
then setting a var(myFlex:Object) to the
movieclip.parent.parent.parent which would be the flex movieclip
then actually grabbing that var "prog" to figure out what
level to set the meter.
//heres the flash side
stop();
var mm:MovieClip = this;
this.parent.parent.parent.parent.addEventListener("setMeter",
cHandler);
function cHandler(event:Event):void
var myFlex:Object = mm.parent.parent.parent;
mtr.gotoAndStop(myFlex.prog);
i know there are definitely better ways to do this but it
works for me. i have used the external interface class and local
connection class but this works pretty well for me. im currently
using the external interface with the yahoo maps api and it works
really well but im having trouble using more than one external
interface instance in the same app....so i went this route.
