Synchronous operations in AS3?

i'm in process of porting ancient dos application flash/as3.the old application able use synchronous approach fit problem well, i'm getting bit of headache trying convert event driven, @ least in elegant way.

 

i have events occur in sequence want display minimal fuss. here's pseudo-code shows want:

 

function start_clicked(e:event):void {     mylabel.text = "five second countdown!";     fillprogressbar(5); // fill bar on 5 second period     mylabel.text = "pausing...";     delaysec(2);     mylabel.text = "thank patience.";     okbutton.enabled = true; }

 

hopefully intention clear, here. each line of code should start after last 1 completes. fillprogressbar() example; there several such operations take time , signal completion via event. in reality, there little bit of if/then/else control flow well.

 

i know how use timer_complete events kick off next action, , in general fine, lengthy sequences best represented control flow, it's getting unwieldy. i've tried keeping nextaction:function var , stuffing (or pulling action queue), nothing seems satisfying. there more common , elegant idiom this?

 

i'm using flashbuilder 4.7 + flex, if there's flex-specific handling this, let me know , happily ask in forum well, moment, believe more general as3 question.

 

thanks!

either use timer class or settimeout.  in general, settimeout easier use it's easy lose scope when using settimeout.
