[comp.sys.mac] More on scrolling in GEM Windows; and Magic Sac

grunau_b@husc4.UUCP (02/04/87)

A few days ago I posted a general question about GEM -- why it is that the
convention on the ST, as opposed to the Mac, is to do scrolling on a separate
screen WITHOUT menu-bar or mouse (like a PC or standard terminal).  On the ST,
the standard seems to be to offer mouse-menu functions in a separate screen
memory address, so you can switch between the scrolling screen and the screen
with GEM windows.

My question was whether this was due to a DEFICIENCY of GEM or whether it just
happened to be easier to code applications this way.

For my two-cents worth, I personally highly prefer the MacIntosh standard.  One
case in point leads me to post this follow-up:  ever since I got a copy of
MacKermit, which runs quite nicely (as any well-behaved Mac application does)
on David Small's Magic Sac emulator, I have been preferring that to Simon Pool's
Uniterm.  My preference stems almost entirely from the freedom of having access
to the Mac's menu bar and desk accessories.  In particular, I have to say that
it is VERY useful to be able to call up the clock DA and have it sitting up in
a corner while I scroll away.

Therefore, I hope it is NOT a deficiency of GEM that leads to the standard as
exemplified in Uniterm.  I think a single-screen method, scrolling WITHIN
windows, is preferable.

As for why I am cross-posting this to comp.sys.mac:  basically, this case-in-
point has its implications for would-be Mac users as well as for ST people.  My
use of Kermit + clock accessory is something that can be acceptably done only on
the ST due to its greater screen size.  Since any well-behaved Mac application
shouldn't care about the size of the screen, you end up being able to use the
greater area to your advantage.  On the Mac, I have found, you either have to
move your terminal window to a point where it is partially off-screen, and you
lose information, or you have to put your clock accessory behind the terminal
window, with just enough of it peeking above it to be able to click it to the
front when you want to tell the time.  On the ST, you can either move the
terminal window down about an inch and a half and put the clock above it, or
you can leave the MacKermit window where it is and put the clock to the right
of it, on screen area that DOESN'T EXIST on the Mac at all!  Mac users should
get a look at the ST's enhanced Mac display -- I have to agree with the BYTE
reviewer of the Mac Plus:  one of the Mac's most limiting factors now is the
size of its screen.  It would definitely benefit from this improvement in its
hardware.
