Finally i got the solution for the designing,what i did is... I just changed the Action-script file for IFRAME by adjusting the x,y coordinates like..
override protected function commitProperties():void
{
super.commitProperties();
if(positionChanged)
{
var point:Point = localToGlobal(new Point(154,24));
callJS(methodMove, point.x, point.y);
positionChanged = false;
}
if(sizeChanged)
{
callJS(methodResize, width, height);
sizeChanged = true;
}
}
so,this makes my issue solved......
