adding variables to movieClip in flash to be used in Flash builder - actionscript-3

Question

I have created a .fla in Flash professional with several rectangles. Each rectangle is a different color and is a separate movie clip. I then have a movie clip (RectContainer) with contains all the rectangles inside of it, and I have added 'AS Linkage' so I can create an instance of this container class in Flash builder (after I've exported as a .swc).
My question is this. What if I wanted to add a variable to each rectangle and how could I read this value from Flash builder.
For example, I want to add a string variable to the red rectangle with the word "red" , the blue rectangle with "blue" etc.
I then want to add listeners to the rectangles, so when they are clicked I can get the color string of the rectangle that was clicked.
for (var i:int = 0; i < rectContainer.numChildren; i++) {
rectContainer.getChildAt(i).addEventListener(MouseEvent.MOUSE_DOWN, fl_Click);
}
function fl_click(event:MouseEvent):void
{
event.currentTarget. ???
}

First, in flash you must set name following like image.
you can access following like it.
not use a currentTarget because a potential risk. If child object a overlap, Your expectations may different. For more information google it.
Exactly what you need to know the difference between target and currentTarget. this is very important concept.
public function Constructor()
{
var container:RectContainer = new RectContainer();
this.addEvent(container);
var i:int = 0;
while(i<container.numChildren)
{
container.addEventListener(MouseEvent.CLICK, onClick);
i++;
}
}
private function onClick(e:MouseEvent):void
{
var mc:MovieClip = e.target as MovieClip;
if(mc.name == "myCircle1")
{
}
else if(mc.name == "myCircle2")
{
}
else if(mc.name == "myCircle3")
{
}
trace(mc.name);
}

You should make a custom class for your rectangles to inherit from (or draw your rectangles in the custom class and forgo the .fla altogether). You can then give a public property to hold the value you desire, create any common functions like a click handler that does something with the color label.
public class MyRectangle extends Sprite {
public var label:String;
public function MyRectangle(){
this.addEventListener(MouseEvent.CLICK, clickHandler,false,0,true);
}
private function clickHandler(e:MouseEvent):void {
trace(label);
}
}
For your rectangles, if in the flash IDE, in their symbol properties put your custom class as the base class.
