And then you go and advocate a single toolkit!  Do you not see the
inherent contradiction there?  While it's certainly not impossible,
the case is hardly obvious for one GUI toolkit for all possible UIs.
You certainly have not presented it, and rantingrick never will.

Also known as "toolkits and widgets".  Talking about such things are
inescapable.

No, that is not the definition of a 'button', not even when we choose
to ignore how it is rendered, which you cannot ignore even if you wish
to pretend you can.  Otherwise, I could always treat hyperlinks and
buttons as equivalent and even interchangeable.  Unfortunately, they
are no such things.

No, as much as we try we cannot divorce presentation from behavior
fully.

MacApp didn't even see the start of cross-platform development until
1996, four years after wxWidgets.  It was not cross-platform from the
start and only became cross-platform when all of Apple's other cross-
platform endeavours failed.
