Tracy, Container::getScrollableRect():Rectangle uses usePadding,
Dumb answer on my part. I had to subclass canvas where I actually wanted the padding to count in the scrollRect. Sorry for the noise, I'm thinking to much these days. I agree, from a design perspective there is no need to do what I said. But for the sake of an explanation, usePadding has to do with the contentPane and how it gets shifted when there is scrollable content, so overriding that would give you padding even though your component is at 0,0 in the contentPane.
