[wxhaskell-users] color/bgcolor or border attribute for panels

[Conal E. <co...@co...>]

I'm trying to selectively highlight panels and controls.  I've tried
setting the "color" and the "bgcolor" attributes, with no visible effect
on panels.  I'm using a row & column layouts with enough spacing to
mouse into the space between controls, and I do get enter events there.
I've also tried using the border attribute on panels and controls, also
without visible result.  I'm running Windows XP.
 
Should color, bgcolor, or border work for panels?  
 
Is there another way to dynamically highlight a control or panel?
 
Thanks!
