want opinions: GUI building environments

[dave]

If anyone has strong opinions or suggestions about Ada-based GUI
development environments, please let me know.

The best product I have seen information about so far, seems to be
ObjectAda from Thomson.  Does anyone have any experience with this?

We use a wide variety of platforms, so something that runs on Windows, a
few flavors of UN*X and, maybe, OS/2 would be nice.

Thanks in advance.

  There is a product on the way from RR Software that is a "thick"
  binding to Windows 95 and Windows NT.  It is somewhat similar to
  Microsoft Foundation Class (maybe a little higher level even than
  MFC) and should work, when ready, with Thomson's compiler, GNAT,
  RR Software's compiler, as well as any other Win 95/NT compiler.

  You might want to check with Ian Goldberg of RR Software to get
  more information. They are in Madison, Wisconsin.  Phone number
  I have (although I think they also have an 800 number) is:
   (608) 251-3133

  The important thing about this product is that it should work with
  everyone's Ada compiler for NT/95 eventually.

I may be missing context from the initial post, and I do not wish
to belittle either of the products mentioned, but what I would really
like is portability between operating systems.  I need to do the same
sort of thing on multiple operating systems, and it would be possible
to have common GUI code do _most_ of it, but there are little nits on
each platform and I am worried about having those overlooked (by me
or by a vendor) in the quest for portability.

For instance, I was reading through the MacApp C++ class library
description, and given that MacApp is from Apple it covers all the
Macintosh-specific nits which might not exist on another platform.
I am not sure if AppleGuide coach marks are among those nits, but
that is an example of a platform-specific feature one is expected
to support by platform zealots.

For Motif the new Common Desktop Environment (which looks like a wide
version of the old LaunchPad on OS/2) expects applications to take
certain actions with regard to saving state on logout.

I know so little about OS/2 that I am sure there must also be some
nits there which do not exist in other GUI environments and thus
might be missed in a general GUI development tool.

So my desire would be for a GUI development environment which had
a winning approach for sorting out these differences, so the result
is a program capable of passing muster with a true Defender of the Faith
for each of the GUI environments on the market.
