Flex Actionscript call parent function - actionscript-3

Question

I have an actionscript file in my flex project. I loaded the actionscript into flex via addElement()
MXML File:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" applicationComplete="init(event)">
<fx:Script>
<![CDATA[
import mx.events.FlexEvent;
public var sv:Myastest;
protected function init(event:FlexEvent):void
{
sv = new Myastest();
addElement(sv);
sv.classfunc();
}
public function mainfunc():void
{
trace("mainfunc called");
}
]]>
</fx:Script>
</s:WindowedApplication>
ActionScript File:
package
{
import flash.events.Event;
import mx.core.UIComponent;
[SWF(frameRate="25", backgroundColor="#000000")]
public class Myastest extends UIComponent
{
public function Myastest()
{
trace("loaded..");
addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
}
private function onAddedToStage(event:Event):void
{
trace("added to stage");
}
public function classfunc():void
{
trace("classfunc called");
}
}
}
How can I call mainfunc() from the actionscript file? Thank you.

Answer 1

IN THE CLASSMANAGEREVENT
public class ManagerEvent
{
public static const EVENT_MAIN_CLASS_FUNC:String = UIDUtil.createUID();
FlexGlobals.topLevelApplication.addEventListener(EVENT_MAIN_CLASS_FUNC, executeMainClassFuncCommand)
public function executeMainClassFuncCommand(event:MainClassFunc):void
{
var cmd:FUNCTIONCommand = new FUNCTCommand();
cmd.execute(event);
}
}
CLASS EVENT
public class MainClassFunc extends Event
{
public function MainClassFunc()
{
super(ManagerEvent.EVENT_MAIN_CLASS_FUNC);
}
}
IN THE CHILD
var mainClassFunc:MainClassFunc = new MainClassFunc();
FlexGlobals.topLevelApplication.dispatchEvent(mainClassFunc);

To expand on RIAStar's comment, you could do this:
MXML File:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" applicationComplete="init(event)">
<fx:Script>
<![CDATA[
import mx.events.FlexEvent;
public var sv:Myastest;
protected function init(event:FlexEvent):void
{
sv = new Myastest();
sv.addEventListener(Myastest.EVENT_NAME, mainfunc);
addElement(sv);
sv.classfunc();
}
public function mainfunc(e:Event):void
{
trace("mainfunc called");
}
]]>
</fx:Script>
</s:WindowedApplication>
ActionScript File:
package
{
import flash.events.Event;
import mx.core.UIComponent;
[SWF(frameRate="25", backgroundColor="#000000")]
public class Myastest extends UIComponent
{
public static const EVENT_NAME:String = "EVENT_NAME";
public function Myastest()
{
trace("loaded..");
addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
}
private function onAddedToStage(event:Event):void
{
trace("added to stage");
}
public function classfunc():void
{
trace("classfunc called");
//assuming you want the mainfunc to get called from here
dispatchEvent(new Event(EVENT_NAME));
}
}
}
Please note that you need to call removeEventListener before you set sv = null.
