Re: [nebula-dev][compositeTable] per-column color paintListener
|
Hi Dave
update: sorry!!! my fault! the bugs I experienced were completely my
fault. There's no bad background-color returned when it has not been set
before!
Was probably some kind of evil-empire-reflex ;-)))
The only thing that's not quite accurate is the control that does not
expand horizontally to the full row-colum area and the background's not
set to its complete horizontal extent (small gaps on the left and on the
right), but no big deal!
I'll try to patch InternalCompositeTable. I think that it would be nice to
have that background-paining automagically (though handwork is no big deal
either) done. What's your opinion?
