Component clone

Question

I am trying to duplicate a flex component at runtime.

For example, if I have this

mx: Button label = "btn" id = "btn" click = "handleClick (event)" / ">

i should be able to call the DuplicateComponent () function, and it should return the user interface component to me in the same way as above, including the listen button for events.

Can someone help me? thanks in advance

Answer 1

Make a copy of the byte array. This code segment should do it for you:

// ActionScript file
import flash.utils.ByteArray;

private function clone(source:Object):*
{
    var myBA:ByteArray = new ByteArray();
    myBA.writeObject(source);
    myBA.position = 0;
    return(myBA.readObject());
}

One note, I myself did not write this code, I'm sure I got it from a message in the Flex Coder list.
