flash - How to create a custom seekbar for music player in actionscript 3.0 -

i'm creating simple music player. play 1 song. want create simple seekbar. 1 graphic work seek component - can moved right , left (between 2 points on x axis: starting point graphic @ moment, , ending point when song ends) , correspond channel.position of song. wrap up: want ask kind soul give me hint of code should use make graphic move on axis x in way corresponds channel.position of song.

this code far:

movieclip_1.stop();  var itsstoped:boolean;  var youpausedit:boolean;  var counter:timer = new timer(100);  var chan:soundchannel;  var song:sound = new sound(); song.load(new urlrequest("wmc2.mp3"));  song.addeventlistener(event.complete, soundloaded); function soundloaded(event:event) { trace("song has been loaded."); }  counter.addeventlistener(timerevent.timer,countcounter);   itsstoped = true;  youpausedit = false;   button_2.addeventlistener(mouseevent.click, presser); function presser(event:mouseevent):void { if(itsstoped == true && youpausedit == true) {     movieclip_1.gotoandplay(1);     chan = song.play(chan.position);     itsstoped = false;  }  else if(itsstoped == false) {     movieclip_1.gotoandstop(1);     chan.stop();     itsstoped = true;     youpausedit = true; }    else if(itsstoped == true && youpausedit == false) {     movieclip_1.gotoandplay(1);     chan = song.play();     counter.start();     itsstoped = false;  }  }   function countcounter(e:timerevent):void { trace(chan.position/song.length); var percentage:uint = 100 * (chan.position / song.length); trace(percentage); if(percentage == 100) {   movieclip_1.gotoandstop(1);     itsstoped = true;     youpausedit = false;     } } 

ignore movieclip_1 it's animation runs when music plays.

something that:

addeventlistener(event.enter_frame,oneframe);  function oneframe(e:event):void {    graphic.x = graphicstartx + music.position/music.length*(graphicendx-graphicstartx); }
