Hi, Jon,
Thanks so much for your response -- it gives me quite a bit to go on.
I suppose that I'll have to weigh the benefits and costs of a palette-
based versus a code-based solution. Do you have a quick idea as to
which might be preferable in a hopefully-shipping Leopard app at some
point in the future?
Cheers,
Andrew

Hi, all,
I'm making a version of John Conway's "Game of Life" cellular
automaton that requires a grid of cells. A previous version of my
program used an NSMatrix subclass of NSCells.
Now, in IB3 on Leopard, I would like to set this up without having
to do substitutions or initializations in code (what I had to do
before).
There doesn't appear to be a way to add a cell by itself to a view
or window -- and this does indeed makes sense to me. There also
doesn't appear to be a way to change the class of an NSButtonCell,
NSTextCell, NSImageCell, et cetera in a matrix to be a custom
subclass of NSCell or NSActionCell -- this also makes sense to me.
What doesn't make sense to me is that I can't figure out a way to
do this. I want my custom NSActionCell (or NSCell, if that would
work) subclass to be in an NSMatrix subclass. Is there no way to
do this from IB3 *without* resorting to a custom palette plugin?
Yeah, to do what you're asking for, we would need an instance of
"NSCell" on the library. Just for a test, I whipped up an IB 3.0
plugin and didn't have to write any code to integrate a cell into
the library.
I started with the plugin project template, and deleted the
framework target, the inspector class and nib, the integration
category, and all of the files from the framework target. Then I
opened the library nib, added some text to the template object that
said "Cell" and hooked up the 'representedObject' outlet of the
library item template container to an NSObject that had its custom
class set to NSCell in the top level of the document. After that, I
could build and load my plug-in and drag vanilla NSCell instances
onto an NSMatrix.
Good Luck -
Jon Hess
Cheers,
Andrew
