Referencing textfield on stage issue - actionscript-3

Question

I use this sample code taken from the docs: all the code is contained inside SocketExample.as, that is the DocumentClass too.
package {
import flash.display.Sprite;
public class SocketExample extends Sprite {
public function SocketExample() {
var socket:CustomSocket = new CustomSocket("127.0.0.1", 5000);
}
}
}
import flash.errors.*;
import flash.events.*;
import flash.net.Socket;
class CustomSocket extends Socket {
private var response:String;
public var txt:TextField;
public function CustomSocket(host:String = null, port:uint = 0) {
super();
configureListeners();
if (host && port) {
super.connect(host, port);
}
}
private function configureListeners():void {
addEventListener(Event.CLOSE, closeHandler);
addEventListener(Event.CONNECT, connectHandler);
addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
addEventListener(ProgressEvent.SOCKET_DATA, socketDataHandler);
}
private function writeln(str:String):void {
str += "\n";
try {
writeUTFBytes(str);
}
catch(e:IOError) {
trace(e);
}
}
private function sendRequest():void {
trace("sendRequest");
response = "";
writeln("GET /");
flush();
}
private function readResponse():void {
var str:String = readUTFBytes(bytesAvailable);
response += str;
}
private function closeHandler(event:Event):void {
trace("closeHandler: " + event);
trace(response.toString());
}
private function connectHandler(event:Event):void {
trace("connectHandler: " + event);
sendRequest();
}
private function ioErrorHandler(event:IOErrorEvent):void {
trace("ioErrorHandler: " + event);
}
private function securityErrorHandler(event:SecurityErrorEvent):void {
trace("securityErrorHandler: " + event);
}
private function socketDataHandler(event:ProgressEvent):void {
trace("socketDataHandler: " + event);
readResponse();
}
public function returnResponse(){
return response.toString();
}
}
On socket close closeHandler gets called. How can I write the value of the response to a textfield on stage? I tried sending a custom Event from CustomSocket closeHandler but, even if I correctly added a listener to the constructor of SocketExample, I did not receive any event. What can I do?

Answer 1

Looks like you already added a public txt field for storing a reference to a text field. How about you create a text field in your SocketExample class, add it to the stage, and then set socket.txt = yourTextField. Then you can just use txt directly in closeHandler.
