If you concern about the fact that your GUI should look as close as possible to "native" GUI look, then GNUStep is not the best solution. Just take a look at this screenshot (http:// www.gnustep.org/images/full-screenshot1.png). It does not look anything like Mac OS X.

If you are familiar with Java, you might want take a look into SWT (http://www.eclipse.org/swt/) from Eclipse folks (http:// www.eclipse.org/). Latest version (3.2) of SWT does look remarkable like "Native" application on all 3 platforms ( Mac OS X, Windows, Linux ). You will miss some Apple specific GUI elements, but "standard" widgets do look pretty good. Another piece of good news, it looks like Eclipse finally got enough people working on Mac OX port, so latest builds of Eclipse finally usable on Mac OS (even Visual Editor!!!).

The obvious solution would be to use GNUStep on the other platforms. The GNUStep Foundation and AppKit frameworks are coded to the OpenStep interface defined by NeXT and Sun way back when. Take a peek at www.gnustep.org . You'll find that the class libraries conform closely to those in Cocoa.

This is absolutely the best approach for Linux. For Windows it would require that the GNU Cygwin libraries are loaded first.

Curious about how people are dealing with cross-platform issues.
Cocoa on Mac to ? on Windows, ? on Linux.

If it was a carbon app all/most code would be in C or C++ and UI could be
dealt with in at least somewhat similar fashion between platforms. Seems to
be one of the potential trade-offs of Cocoa vs Carbon that Apple doesn't
address much.


I know I can code in C or C++ within Cocoa as well but how are most real
Cocoa developers dealing with this and the UI porting issues? Or are most
Cocoa developed apps staying Mac only?


Is the potential faster/easier coding in Cocoa(is it?) offset by added time
and work to port to other platforms?


Thanks.
