1. Add Metadata tag in your component with the name of your event.
<mx:Metadata>
[Event(name="login", type="flash.events.Event")]
</mx:Metadata>
2. Catch that event in your component
<Login x="333" y="56" login="handleTestEvent(event)"/>
3. Add AS to handle the event.
public function handleTestEvent(eventObj:Event):void {
mx.controls.Alert.show(eventObj.currentTarget,'Test');
}
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns="*"
layout="absolute" applicationComplete="onComplete()">
<mx:Script>
<![CDATA[
import mx.controls.Alert;
[Bindable]
public var status:String = "";
public function onComplete():void {
status += "Add Event Listener...\n";
Application.application.addEventListener("test",onTestEvent);
}
public function onTestEvent(event:Event):void {
Application.application.status += "Test Event
occured...\n";
}
public function dispatchTextEvent():void {
var event:Event = new Event("test");
dispatchEvent( event );
status += "Event Dispatched...\n";
}
public function handleTestEvent(eventObj:Event):void {
mx.controls.Alert.show(eventObj.currentTarget,'Test');
}
]]>
</mx:Script>
<mx:Button x="66" y="56" label="Login1" click="dispatchTextEvent()" />
<mx:TextArea x="66" y="123" width="393" height="243" text="{status}"/>
<Login x="333" y="56" login="handleTestEvent(event)"/>
</mx:Application>
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" xmlns="*">
<mx:Metadata>
[Event(name="login", type="flash.events.Event")]
</mx:Metadata>
<mx:Script>
<![CDATA[
import mx.controls.Alert;
public function loginUser():void
{
var event:Event = new Event("login");
dispatchEvent( event );
Application.application.status += "Dispatch login
event...\n";
}
]]>
</mx:Script>
<mx:ControlBar>
<mx:Button label="Login2" click="loginUser()" />
</mx:ControlBar>
</mx:Canvas>

Hmm, the code you posted for Login.mxml dispatches a "login" event,
not "test", so that's one thing to be aware of. You'll need to add
the listener to the Login object, which you can do by giving the
Login component an id (<Login id="loginComponentId" ...>) and then
calling something similar to:
loginComponentId.addEventListener("login", onLoginEvent).
