A similar issue exists in the Linux world. Older WMs like twm and
sawfish allow creation of windows that are larger than the display.
Unfortunately these are no longer supported. The "native" window
manager in Fedora, MetaCity, will allow you to manually adjust a window
to whatever size you like, and manages those windows just fine, but will
not allow you to CREATE a window that does not fit on the screen. This
is a large pain in your southern extremities when you are working with
4000 x 4000 images and have a few tens of thousands of lines of code
built around the assumption that when you open a window with a specified
xsize and ysize, you GET a window with that xsize and ysize. (This
seems to be part of a general move in the Linux world away from the sort
of flexibility that prevents off-the-street users from being happy.)
A very sharp student of mine tried to hack MetaCity, but threw up his
hands in the maze of conditionals inside the code. And when he asked
one of the developers about it, the answer was a very predictable, "Open
windows larger than the screen? You aren't supposed to want to do that.
What kind of an idiot are you, anyway?"
I'd be interested in hearing the outcome of peoples' experience with
window managers and multiple displays in OS X. As of a day ago I have a
PowerMAC, a 20 inch display, and a 30 inch display sitting in my lab. I
would be perfectly happy if I could run X11 full screen on the 30 inch
display with some reasonable window manager (reasonable = let's me
create absurdly large windows), while running aqua in the 20 inch display.
I'm kind of afraid of taking the hardware out of the box because I know
that when I do, I'm going to get sucked into issues like this for a month.
Cheers,
Jeff
