Question

I understand how to declaratively assign a method to be called when an Image receives a MouseMove event.

    <mx:Image          id='oneCent'         mouseMove='dragIt(event, 1);'     /> 

How do I do this programmatically in Flex/AS3?

EDIT: Thanks for the comments. Here’s what I have so far:

          myImage = new Image();             myImage.id = 'oneCent';             myImage.addEventListener(MouseEvent.MOUSE_MOVE, dragIt); 

The code snippet above assigns the dragIt method to the MOUSE_MOVE event for myImage. So far, so good. How do I pass in the 2nd parameter to the call to dragIt?

Answer 1

You can’t pass the second param directly – so add it to myImage:

myImage = new Image(); myImage.id = 'oneCent'; myImage.num = 1; myImage.addEventListener(MouseEvent.MOUSE_MOVE, dragIt); 

Then in the dragit function:

function dragIt(event:MouseEvent):void {     trace('PARAM =', event.target.num, event.target.id); } 

Where event.target automatically becomes a reference to the image
