Rather than sending an event to a component, what you do is declare a
public function in your component, then call it from the application.
so... in myComp
public function someFunction(var param1:type):void
{
//do stuff
}
and out in your main code you need to give your myComp an id...
id="myComp". Then in your button click handler call
myComp.someFunction(blah);

Hi, I'm able to send a custom event from a component to an
application, but how do I send a custom event from the application to
a component?
example code:
mycomp.mxml:
<?xml version="1.0" encoding="utf- 8"?>
<!--this is myapp.mxml-- >
<mx:Application xmlns:mx="http://www.adobe. com/2006/ mxml
<http://www.adobe.com/2006/mxml>"
layout="absolute"
xmlns:comp=" *" xmlns:events= "flash.events. *" creationComplete=
"init()">
<mx:Metadata>
[Event(name= "appEvent" , type="flash. events.Event" )]
</mx:Metadata>
<mx:Script>
<![CDATA[
import mx.controls. Alert;
private function init():void {
addEventListener( "compEvent" ,compEventHandle r);
}
private function compEventHandler( e:Event): void {
Alert.show(" event received from component");
}
private function sendEvent(e: Event):void {
var myappEvent:Event = new Event("appEvent" , true,true);
dispatchEvent( myappEvent) ;
}
]]>
</mx:Script>
<comp:mycomp />
<mx:Button label="send event to component" id="appbutton"
click="sendEvent( event)" />
</mx:Application>
component:
<?xml version="1.0" encoding="utf- 8"?>
<!--this is mycomp.mxml- ->
<mx:Canvas xmlns:mx="http://www.adobe. com/2006/ mxml
<http://www.adobe.com/2006/mxml>" width="400"
height="300" creationComplete= "compInit( )">
<mx:Metadata>
[Event(name= "compEvent" , type="flash. events.Event" )]
</mx:Metadata>
<mx:Script >
<![CDATA[
import mx.controls. Alert;

}
private function appEventHandler( e:Event): void {

}
private function sendEvent(e: Event):void {
var mycompEvent: Event = new Event("compEvent" , true,true);
dispatchEvent( mycompEvent) ;
}
]]>
</mx:Script>
<mx:Button id="mybutton" x="200" label="send event to application"
click="sendEvent( event)" />
</mx:Canvas>
thanks!
