I'm changing the canvas background colour when the dragenter event
fires..
like this.
foo.addEventListener(dragEvent.DRAG_ENTER,function
(event:DragEvent) {foo.setstyle("background","colour") };
i thought that each object i create is its own instance in memory,
therefore when i apply an event listener that event is it's own
entity for each object regardless of naming.
Would an better alternative be something along the lines of this..
<<pseudo>>
BEGIN LOOP
ARRAY[counter] = NEW extendedCanvasObj
ARRAY[counter]. setstyles
ARRAY[counter].addEventListener
container.addChild(ARRAY[counter])
END LOOP
Or is there a smarter way of doing it, any links where i can read up
on this would be appreciated.
cheers
