If it's possible, I would suggest setting the user-specific information
that gets set when you change a file's associated app using the Info
window in the Finder. Since that information is user-specific, your
users will be able to easily change the setting, and people they send
the files to will be able to have the files open with their chosen app.
Unfortunately, I'm not sure how to set this programmatically, but it
might be that someone else on this list knows.

Thanks, Dave.
Following your suggestion, I found out through a very circuitous route
that
Cocoa actually supports these directly now. By overriding
fileAttributesToWriteToFile in my MyDocument class, I was able to
stick in a
NSFileHFSCreatorCode key and a NSFileHFSTypeCode key, allowing the
owner/file type to be written to the file on HFS systems.
Now I get perfect icon behavior, although I think I'll add some logic
to
distinguish between "created" files and "processed" files created by
another
application. Maybe even a preference to control this behavior. Anyone
have
any UI rules to quote about that approach?
As always,
Thanks!

Hi all once again,
The archives haven't been much help in my particular question -- if
it's been
covered, I humbly apologize!
I'll preface this by saying that I *can* make document icons work
for *my
own* file types, e.g., document.mytype.
Where I'm running into trouble is getting my document icons to stick
for
other, competing file types. For example, imagine I'm trying to
process
.html, .htm, and/or .php files -- saving a document uses the icon
for the
default program for the file type. In this case, BBEdit for .php
files, and
Mozilla for .html/.htm files. Sure, when processing pre-made files,
I'm not
necessarily against this behavior. But when creating a NEW file and
saving
it, I think it should use my own icons.
Of course, when I Get-Info in Finder, my program's saved files --
even the
ones my program created -- are "open with" BBEdit and/or Mozilla.
When I
change the "open with" setting, my icons pop up normally. But I
guess I feel
I shouldn't have to change the "open with" on files that my own
program
saved.
Under pre-X systems, I'd look at creator codes, but these sadly seem
to have
disappeared for Cocoa applications, although I found lots of good
stuff for
them in Carbon documentation (which I don't really want to tackle!).
Any ideas, or at least a concrete place I can look to figure it out
myself?
You will have to use the types/creator API's from Carbon, although
those are
slightly deprecated.
