Hi
Dirk,
I haven't quite got my head around the whole Delegate thing
yet.
When
you say "This enforces that the
function is called with the right scope" what do you
mean?
I
understand scope - so if I set my labelFunction without using the Delegate
class, is there a chance of using or changing variables in the wrong
place - or something like that?
Simon

I'm glad it worked. There was a mistake in my first post: the object you want to call the function on needs to be added to the Delegate call. In your case:
dg.getColumnAt( 0 ).labelFunction = mx.utils.Delegate.create(dgVH, dgVH.labelFunc);
This enforces that the function is called with the right scope.

Hi Dirk,
Thanks for the suggestion, I hadn't thought of that, but it didn't work when I tried it. So I tried just
dg.getColumnAt( 0 ).labelFunction = dgVH.labelFunc;
and this did work. Its a big improvement over wrapping external class functions with a function!
But what I was originally trying to do was set the labelfunction in the MXML which was giving the error I described. I also tried your suggestion here, but this didn't work either.
Thanks for your pointer,
Regards,
Simon Fifield

Have you tried using the mx.utils.Delegate class?
myGrid.getColumnAt(0).labelFunction = mx.utils.Delegate.create(anotherClassInstance, anotherFunction);
haven't tested it, but it should work.
Dirk.

At the moment a labelFunction or sortFunction has to be defined in the MXML file that it is being used in.
It would be nice to be able to use an external Class to achieve this and thus enhance code clarity and re-use.
Does anyone have any ideas on this?
Kind Regards,
