Question: **Is it possible to pass constructor arguments to instance objects which I place on the stage?** Are the instantiations of instance objects centralized somewhere as with .NET WinForms so I can just edit the `xxx = new CustomRecangle()` constructor? 

```
public class CustomRectangle extends MovieClip {         
    public function CustomRectangle(width:int, height:int) {
        this.width = width;
        this.height = height;
    }
}

```

Answer: 
Yes you can, but in the extended class' constructor don't forget to call the super() function witch will call the constructor of the baseclass.
