Re: [flexcoders] Re: Custom UIComponent creating problem

[Michael Schmalle]

Hi,It's not that it is not getting added to the display list, it's that UIComponet does not have a border.If you want something with a border, you either have to create a border skin instance in your extended UIComponent subclass OR subclass container that has a border(which is expensive if your are doing something simple).
Best bet is to create a border skin, size it in updateDisplayList().Peace, MikeOn 8/15/06, lostinrecursion <

            Forgive me, but are you adding the Component to the Display List
before you want to see it? Any objects which you want to be visual
must be explicitly added to the Display List if they are custom drawn.

See DisplayList on ASDoc.
