actionscript 3 - Change text from other class with AS3? -

i have action script in first layer , imports customsocket class external .as file. when receive command on socket want edit gui objects. example, when command time 23 server want change dynamic text box timerbox value 23. have method called processcommand(cmd:string) in customsocket class, don't know how change text. can timerbox.text = "23"; doesn't work in external class?

if 'customsocket' not document class, need specify reference timeline in class.

for general example,

while importing class,

import customsocket;  csobj:customsocket = new customsocket(this); 

then, inside class, in constructor

public function librarys(_ref:object):void {   timelineref = _ref; } 

then in class can say,

timelineref.timebox.text = "23";
