How to link carbon framework to NS port?

How to link carbon framework to NS port?

[Vebjorn Ljosa]

I am working on a fullscreen patch for the NS port.  I would like to
use the SetSystemUIMode API to auto-hide the menu bar when in
"fullboth" mode.  That API, however, is part of the Carbon framework.
Two questions:

1. Will using the SetSystemUIMode work on GNUstep?

2. How do I modify the autoconf setup so that "-framework Carbon" is
passed to gcc when linking the NS port?

Thanks,
Vebjorn

No.  Nothing Carbon-related is implemented in GNUstep, and never will
be.  Think of GNUstep as free Cocoa + more (GNU extensions and support
for other platforms).

That's easy, but I'm not sure if it is desirable.  See the
temacs${EXEEXT} rule in src/Makefile.in.  If Carbon is guaranteed to
be available on all Apple systems, you don't need any autoconf tests.

I have a partial implementation of fullscreen mode (without direct use  
of SetSystemUIMode) using the standard Cocoa (and perhaps NS) APIs  
within NSView.

It works, but after switching back there are problems (redisplay  
issues mainly) with the scroll bars.

It's in the Aquamacs master branch.

If you get it to work better (even with Carbon if need be) then that'd  
be great.

I'd strongly prefer to avoid Carbon -- it would add to the resource
footprint on Mac systems and necessitate additional ifdef'd
implementations to work on GNUstep.  It places a heavier load on
maintainers both to track two implementations and to be familiar
with another API.

If the Aquamacs implementation is close to working let's try to get
that one polished up.

Agreed, absolutely.

OK, if someone wants to take a look:

The problem is that after switching back from fullscreen mode, the  
scrollbar or some visual window area (width) variable seems "messed  
up": it flickers whenever you scroll (using keys).  I haven't figured  
it out and won't be able to work on this.

That's great!

I tried out Aquamacs but couldn't immediately see any problems.  How
do you reproduce the bug?

Go into fullscreen mode, then out again.  Now scroll up/down and  
you'll see the vertical scrollbar flicker (the buffer has to be large  
enough of course).  At least it does that for me and some testers.

I can't reproduce it (Aquamacs 1.8c2 binary from website, Leopard), so
I'll go ahead and port your work to GNU Emacs.  I hope to be able to
make it work without changing frame.c, as I managed (except for one
line) when I did this in CarbonEmacs.

Vebjorn, 1.8 is based on Emacs 22 as the about screen shows.

Download a 2.0dev nightly build or today's 2.0 preview release which  
is Cocoa and based on 23.1.  That's what corresponds to the master  
branch.
