Or a simple linedraw, I've used the watch once with the tween class.
var test_mc:MovieClip = this.createEmptyMovieClip("test_mc",1);
test_mc.lineWidth = 0;
var f:Function = function(prop, oldVal, newVal){
this.clear();
this.lineStyle(1,0x000000);
this.moveTo(0,25);
this.lineTo(newVal,25);
return newVal;
}
test_mc.watch("lineWidth",f);
this.onEnterFrame = function(){
test_mc.lineWidth++;
}
