[MacRuby-devel] HotCocoa subclassing NSView

[Matt Aimonetti]

Thanks Rich, but if I do what you recommended, I guess I would not be able
to use all the NSView extra stuff defined by the existing NSView mapping
(constants, custom methods etc..).

Wouldn't be better to make each mapping a mixin? That would allow us to
reuse some default settings and subclassing a mapped class would give us all
the mapping goodies.
