I believe you can set up
var myCheckBoxFactory:ClassFactory = new ClassFactory(CheckBox);
myCheckBoxFactory.properties = { enabled : determineEnabled() };
and then use that instead of just CheckBox as your renderer.
I'm actually working on something similar and what I'd like to know is
if there is a way to have this driven by the data backing each row. That
is, if I have a grid with columns id and isGreat, I'd like something
like
id | isGreat
1 | \x\
2 | \ \
3 | [x]
4 | [ ]
where this is driven by something like
canSetGreatness(id:Number):Boolean {
return id == 3 || id == 4;
}
(obviously with more logic in the real check function) and where
where [ ] denotes a checkbox and \ \ denotes a disabled checkbox.
Is this doable?

Yeah I'm wanting to make it where certain users can't click the
checkbox. so enabled="false" is what I'm looking for.
Also though, is there a way to catch the click on the checkbox and
then run a check, then if the check returns true allow the box to be
clicked and if it returns false alow it not to be clicked.
Thanks,
-David
