   Actually, come to think of it, this should be do-able without actually
writing much code ... assuming you're on a NeXT =8) ... you can create
a ScrollView, set its docview to a matrix of textcells, and there you
go. You'd have to create a new textcell each time you wanted to add a
string but that shouldn't be too difficult. The problem with this
is it's sometimes unclear what messages you need to send to update the
display. I'm not near a NeXT so I can't say offhand.
   Or, you could use the "BrowserBay" and "BrowserMatrix" classes that
have been on the NeXT archives for a while (in fact, they're about the only
things in the classes/ directories). These look more like the Directory
Browser, and are meant to act like it, but you can probably tell the cells
not to allow themselves to be selected ... 
   And if you're *not* on a NeXT, maybe someone who is has benefitted from
this use of bandwidth... (Notice I wrote this entire article with only
reused code!)
