Re: [OT] Carbon and WWDC'07



Your argument seems a little disingenuous. Do you expect your PC
developers to be familiar with Carbon? Do they have to understand how
the File Manager works? If not, would they be seriously disadvantaged
if your Mac code was in Cocoa? If so, how is that any different from
asking them to understand Obj-C?

And again, the vast majority of conceptual information that you need
to gain familiarity with is in Cocoa, the framework. Objective-c is
very small and straightforward. The problems mostly come from
expecting it to behave like C++ and having to unlearn that, which
apparently some find challenging.

Finally, you can mix and match C++ and Objective-C as much as is
needed. No, you cannot subclass a C++ class in Obj-C or vice versa,
but this is far from a requirement as you assert.

Take a look at WebKit/WebCore. WebCore is C++ and derived from KHTML.
WebKit is a fairly thin layer on top for embedding and rendering in
Cocoa. There also front-ends on top of WebCore for KDE, GTK+ and
Symbian S60. It is certainly possible.

That's a great point. What happens when our PC engineers need to
duplicate a feature on Windows for which our Mac engineers have
already written? With our current team, I develop all new features,
write the cross-platform code and the Mac UI, then the PC side gets
added. If all our Mac code was in Obj-C, how would the PC guys read
it to be able to see how I did things? I sure wouldn't want to be a
PC guy being told that I had to learn Obj-C just so I could
understand it. Then there are the guys who work on the server
product, which is also based on the same cross-platform code and has
Mac, Windows, and Unix versions.

Besides, being cross-platform means inheriting cross-platform C++
classes in a lot of cases. Obj-C can't inherit from C++, right?
