Hi,

I am wanted to know how can i pass a parameter to the function which I’m calling using Delegate class. I know to pass params having static values such as true / false or a static string “hello”.

```auto
var myFunc:Function = btn.onRelease = Delegate.create(tihs, releaseHandler);
myFunc. **str** = "hello";

function releaseHandler()
{
    trace("my param = " + **arguments.caller.str** ); //output: hello 
}

```

Here \*\*str \*\*can be retrieved as ‘ **arguments.caller.str** ’ inside the function.

But in case i want to pass the reference of the ‘btn’ button. Then how can i do this ?

thanks.
