Subject:  0) TOPIC: WHAT ARE OTHER RELEVANT NEWSGROUPS?

[Last modified: Dec 92]

Answer: This newsgroup is comp.windows.x.motif.  The nearest related group is
comp.windows.x.  It also maintains an FAQ, which deals in all sorts of X, Xlib
and Xt questions. Look there for answers to questions such as "How do I get a
screendump of my application?", "where do I get X11R4", etc.  Other groups
which may have relevant information are comp.windows.x.pex,
comp.windows.x.apps, comp.windows.x.intrinsics, comp.windows.news,
comp.windows.misc and comp.windows.open-look.

-----------------------------------------------------------------------------
Subject:  1) TOPIC: FTP ARCHIVES

-----------------------------------------------------------------------------
Subject:  2)* Is the FAQ list available for FTP anywhere?

[Last modified: November 92]

Answer: A number of FAQ's (including this one) are available for anonymous ftp
at pit-manager.mit.edu, 18.172.1.27 under the directory pub/usenet.  (Motif is
under pub/usenet/comp.windows.x.motif) There is also a mail server called
[e-mail].  To retrieve a file send mail to the server
with a subject or body similar to

        send usenet/comp.windows.x.motif/Frequently_Asked_Questions_About_Motif_(Part_1_of_3)

This service is looked after by Jonathan Kamens ([e-mail]).

It has also been placed in contrib/Motif-FAQ at export.lcs.mit.edu.

The FAQ is also available from csc.canberra.edu.au (137.92.1.1) by anonymous
ftp.  It is in the file /pub/motif/Motif-FAQ

This files are also accessible from WAIS (Wide Area Information System) under
UC-Motif-FAQ, allowing keyword-based searches of the FAQ.

-----------------------------------------------------------------------------
Subject:  3)*  Is this newsgroup accessible via email?

[Last modified: December 92]

Answer: An email link was maintained by Kee Hinckley. To join, send mail to
[e-mail] or [e-mail].  However, Kee
has indicated that he doesn't want to do this anymore, and the state of the
mail service is uncertain.

-----------------------------------------------------------------------------
Subject:  4) Is this newsgroup archived?

[Last modified: November 1992]

Answer: The newsgroup files from August 1991 are available from
csc.canberra.edu.au (137.92.1.1) by anonymous ftp.  They are in the directory
/pub/motif/comp.windows.x.motif.

These files are also accessible from WAIS (Wide Area Information System) under
comp.windows.x.motif, allowing keyword-based searches of the newsgroup
articles (this time on machine services.canberra.edu.au (137.92.1.12)).

-----------------------------------------------------------------------------
Subject:  5) Is the mail list motif-talk archived?

Answer: If you have purchased support from OSF then you have access to their
archive server for motif-talk.

-----------------------------------------------------------------------------
Subject:  6) TOPIC: OSF AND MOTIF

-----------------------------------------------------------------------------
Subject:  7)*  What versions of Motif are there?
[Last modified: November 92]

Answer: Motif 1.0 is based on the R3 toolkit.  There are patch releases to
1.0: 1.0.1, 1.0.A, 1.0.2 and 1.0.3, 1.0.4, 1.0.5. 1.0.A was a fairly major
patch, as it involved a complete re-engineering of UIL and Mrm.  Almost
everyone who has 1.0.x has either 1.0.A or 1.0.3.

Motif 1.1 is based on the R4 toolkit.  The intial version was Motif 1.1.0.
Motif 1.1.1 has been released as a patch to licensees with Full Support or
Technical Update service.  Motif 1.1.2 is a patch release which contains the
necessary changes to fix over 80 bugs reported against Motif. It is available
to support contract holders (including both full support and update service).
The 1.1.3 release fixed a further 150 bugs and was available from August 1991
to support contract holders (including both full support and update service).
1.1.4 offers X11R5 support, but is not an X11R5 product.  1.1.5 was released
in June 92 to licensees who hold a Motif Full Support or Update Support
contract

Motif 1.2.0 was released in April 1992 and is based on the X11R5 toolkit.  It
offers increased compatibility with international standards,  PC-style
behavior and binary compatibility with OSF/Motif 1.1 applications.  New
features include drag-and-drop, tear- off menus, toolkit enhancements and new
documentation.  toolkit.  The code is totally ANSI C.  OSF distributes a 10
pages sheet entitled "OSF/Motif R1.1 to R1.2: detailed overview of changes",
which is available from OSF Motif direct channels.  (617-621-7300 or email
[e-mail])

Motif 1.2.1 was released September 92.  Due to an optimisation from 1.2.0 to
1.2.1 object code compiled under 1.2.1 (that is, using 1.2.1 header files)
will not link with 1.2.0 libraries (and, very probably, clients that use
shared libraries and are linked against 1.2.1 won't startup against 1.2).

From [e-mail]: "Motif 2.0 will ship well before the sun burns out,
unless we decide to change the name first, and will contain a free plastic
spaceman in every box."

-----------------------------------------------------------------------------
Subject:  8)*  Where can I get Motif?

[Last modified: November 92]

Answer:
    Various hardware vendors produce developer's toolkits of binaries, header
files, and documentation; check your hardware vendor, particularly if that
vendor is an OSF member. Systems known to be shipping now: HP (sans UIL),
Apollo (sans UIL), SCO, ICS, Mips (RISCwindows=X11R3 + full Motif), IBM, Data
General for AViioNs (includes UIL), Bull (?), Concurrent Computer Corporation
5000, 6000, 8000 series machines, Convex, Sequent.

    In addition, independent binary vendors produce Motif toolkits . ICS makes
several binary kits, notably for Sun, DEC, Apple; Quest (408-496-1900) sells
kits for Suns, as well; IXI ([phone]) offers kits for Sun3 (SunOS 3.5
or later, and Sun4 (SunOS 4.0.1 or later). Unipalm XTech ([phone]; or
Aurora Technologies 617-577-1288 in USA) offers a binary kit for Suns based on
Motif 1.1, with shared libraries.  NSL ([phone]; [e-mail])
offers kits for the Sun 3 and Sun 4.  [An FAQ is for "personal opinions" on
these toolkits.  I don't think it is appropriate to give such opinions through
this particular posting, so I haven't included any.] In Australia, Information
Technology Consultants Pty Ltd has Motif 1.1.2 for Sun Sparc 4.1 ( phone on
[phone], fax on [phone] or e-mail to [e-mail])
SILOGIC (+33 61.57.95.95), 78 chemin des Sept Deniers - 31200 TOULOUSE FRANCE
sells Motif 1.1 and 1.2 on Sun4 machines. They also provide customers with
Motif maintenance and support, and do consulting on the X window System at
large, including software development.



  The kits include varied levels of bug-fixing and support for shared
libraries.  BIM (Fax : [phone]) offer Motif 1.1 for Sun-3, Sun-4,
Sun-386i. Includes shared libraries.  Metrolink Inc. ([phone],
[e-mail]; in Europe contact ADNT, (33 1) 3956 5333) ships an
implementation of X11R4 and Motif 1.1 for several 386 systems.

    An OSF/Motif source license must be obtained from OSF before source can be
obtained from the Open Software Foundation. Call the Direct Channel Desk at
OSF at 617-621-7300 or email [e-mail] for ordering information.  In
addition to the full Motif source, "option C" allows you to purchase source
for the window manager mwm to run on X terminals.


-----------------------------------------------------------------------------
Subject:  9) Is there a list of Motif bugs?

Answer: With each patch release of Motif shipped, there is a list of known
bugs provided.  The filename on the tape is "./OPENBUGS".  There is also a
list of all the issues closed/resolved in that patch.  That is found as part
of the "./README-1.1.n" (where n is the patch number) file.

These are the only OSF published lists.

No-one else seems to publish a list.


-----------------------------------------------------------------------------
Subject: 10) Where can I get public domain Motif source?

Answer: You cannot.  Motif source is not publically available.


-----------------------------------------------------------------------------
Subject: 11)  Are the Motif examples publically available?

[Last modified: November 92]

Answer: OSF has produced a list of which of the example programs can be
distributed. Call OSF Direct for a copy of it.  Most of the example programs
have been freed from distribution limitations so should be available.

In addition to these, many programs on export.lcs.mit.edu in the contrib
directory use Motif.  Source code posted to comp.sources.x often uses Motif.
The examples from Dan Heller's book are on export in
/contrib/OReilly/motif/examples.tar.Z.  The examples from Doug Young's book
are on export in /contrib/young.motif.Z The examples from Thomas Berlages's
book are on export in /contrib/berlage.motif.Z The examples from Donald L.
McMinds's book are on export in /contrib/mastering.motif.tar.Z The examples
from Jan Newmarch's book are export in /contrib/newmarch.tar.Z



-----------------------------------------------------------------------------
Subject: 12)  Has anyone done a public domain Motif lookalike?

[Last modified: September 92]

Answer: Not yet.  The specification is available (AES), and the validation
suite can be bought, but no-one has taken up the challenge.  There are some
commercial lookalikes (Looking Glass and Neuron Data), but no workalikes.

Applications that follow the Style Guide might be certified Motif-compliant
through the checklist process, even though they're not using OSF/Motif
binaries.

Tcl is available for ftp from allspice.berkeley.edu, and although implemented
without Xt, is reported to look like Motif.  Strom Sytems (18666 Redmond Way
o-2118, Redmond, WA 98052-6725) have a Simple Toolkit for X-Windows (sic) that
appears to follow the Style Guide even though it doesn't quite look like
Motif.

MOOLIT is a USL product that can be runtime switched between the Sun Open Look
and Motif appearance.  It is based on  OLIT 4i.


-----------------------------------------------------------------------------
Subject: 13) Does anyone from OSF pay attention to our questions/suggestions?

Answer: Yes, and they quite often post answers too. But they may not respond
to *your* problem because they have other things to do as well.  This
newsgroup is not run by OSF, and has no formal connection with OSF.  OSF is a
member-driven company.  The membership (and anyone can be a member) provides
the primary input for future development of Motif.

-----------------------------------------------------------------------------
Subject: 14) Does OSF have an application compliance validation service?

Answer: They have a checklist and a certification process which you can
request from them.  Ask for the Level One Certification Checklist.  The
process is one of self-certification.  It tests only the appearance and
behavior of the application against Motif style.  The product will also be put
in the OSF reference listing.  There's a one-time fee of $250.  According to
the master license agreement, you can't use any OSF identifying mark unless
you have done a certification.


-----------------------------------------------------------------------------
Subject: 15) What is the motif-talk mailing list?

Answer: The motif-talk mailing list is only for those who have purchased a
Motif source code license. You can be placed on this list by emailing to
[e-mail], citing your Company name and source license
number.



-----------------------------------------------------------------------------
Subject: 16) What MIT patches do I use, and when do I use fix-osf?

Answer: The Motif 1.1.0 tape contains MIT patches 1-14. Apply these and any
others you can get.  If your MIT patch level only goes up to fix-16, you also
need to apply fix-osf.  Fix-osf was an emergency patch for a problem that
existed when the Motif 1.1 tape was cut, The MIT fix-17 completely superseded
osf-fix, so if you have applied fix-17 do not apply fix-osf.  The 1.1.1 tape
contains MIT fixes 15-18, as well as an OSF-developed fix that deals with a
subtle bug in the Selection mechanism of the Intrinsics.  Most people will
have fix-15 to 18 by now; if you don't have them:

        Back out fix-osf if you have applied it
        Apply fix-15 to 18
        Apply fix-osf-1.1.1

The Selection fix was submitted to MIT, who came up with a different fix.  It
will not be made into an R4 fix but should be in R5. The MIT fix was posted to
motif-talk.


-----------------------------------------------------------------------------
Subject: 17) How does Motif work with X11R5?

Answer: Motif 1.1.X is only intended to be built with X11R4.  Motif 1.2.X is
for X11R5.  however, Motif 1.1.4 has been set to also work with X11R5.

For Motif 1.1.1, 1.1.2 and 1.1.3 you will need to compile Xlib and Xt with a
MOTIF_BC flag set to YES (page 8, section 3.3 of the R5 release notes), or
you'll also have a link problem (LowerCase) and a fatal run time problem
(XContext manager).  If your applications come up with "Unknown keysym name:
osfActivate" errors, check the variable ProjectRoot. The name
/$PROJECTROOT/lib/XKeysymDB will have been wired into your Xlib.

In Motif 1.1.0, XtCallCallback uses NULL as the first argument instead of a
widget ID. This was ok under R4, but must be changed in the source for R5. It
was changed by OSF from Motif 1.1.1 onward.

Mrm won't work at all (can't link since it uses an X private variable that has
disappeared in R5).  Thre is an MIT patch that may fix this??  [I confess
ignorance of Mrm and UIL].

-----------------------------------------------------------------------------
Subject: 18)  How can I find which version of Motif I have?

Answer: The macro XmVERSION gives you the version number.  The macro
XmREVISION gives you the major revision number.  The macro XmVersion combines
these e.g. a value of 1002 is Motif 1.2.

To find the minor revision number is not easy.  From Motif 1.1.3 onwards, try
this:

   'strings `which mwm` | grep OSF'.

to get the full version number e.g. 1.1.3.


-----------------------------------------------------------------------------
Subject: 19) TOPIC: LITERATURE

-----------------------------------------------------------------------------
Subject: 20)  What books should I read or do I need to program using Motif?

[Last modified: November 92]

Answer: Ken Lee of the DEC Western Software Laboratory ([e-mail])
regularly posts to comp.windows.x and ba.windows.x a list of reference books
and articles on X and X programming.  In FAQ comp.windows.x an extract of his
list appears. Specifically for Motif programming, though:

OSF/Motif Programmers Guide, Prentice-Hall 13-640525-8 (Motif 1.0) ISBN 0-13-
640681-5 (Motif 1.1) (NB: This makes use of the demo programs that you get
with a Motif source license.  The programs are not included and may or may not
be available on your system.)

OSF/Motif Programmers Reference Manual, Prentice-Hall 13-640517-17 (Motif 1.0)
 ISBN 0-13-640616-5 (Motif 1.1) You will need this for the system calls.

OSF/Motif Style Guide, Prentice-Hall 13-640491-X (Motif 1.0) ISBN 0-13-
640673-4 (Motif 1.1) You will need this to get some idea of how to write
programs with the correct `look and feel'.

You should read at least one of the the non-OSF books on Motif:

Young, Doug. "The X Window System: Applications and Programming with Xt (Motif
Version)," Prentice Hall, 1989 (ISBN 0-13-497074-8). The excellent tutorial "X
Window Systems Programming and Applications with Xt," (ISBN 0-13-972167-3)
updated for Motif. [The examples from the Motif version are available on
export in ~ftp/contrib/young.motif.tar.Z]

Marshall Brain at [e-mail] posted a set of simple and useful
Motif tutorials.

Berlage, Thomas Berlage, OSF/Motif: Concepts and Programming, Addison-Wesley,
UK, 1991. ISBN 0-201-55792-4.

Johnson, Eric F. and Kevin Reichard, Power Programming Motif, MIS: Press,
Portland, OR, 1991. ISBN 1-55828-059-6. Book with disk, ISBN 1-55828-061-8.

Heller, Dan, The Motif Programming Manual, Volume 6 of the O'Reilly series on
X.  This is the most complete volume on Motif programming available.  ISBN 0-
937175-70-6.

Barkakati, Nabajyoti, W Window System Programming, SAMS. ISBN 0-672-22750-9.
This contains a section on Motif.

Newmarch, Jan, The X Window System and Motif - A Fast Track Approach.
Addison-Wesley, ISBN 0-201-53931-4.

Subject: 21) TOPIC: MWM

-----------------------------------------------------------------------------
Subject: 22) What is the difference between Motif and mwm?

Answer: mwm is a window manager. Motif itself is made up of four parts: a
User-Interface Guideline, an API toolkit of `C' routines which helps in the
building of applications which conform to the Guideline, the window manager
mwm, and a language UIL which is designed to ease user interface development.
In general mwm will run an application built with any X-windows API, and in
general an application built using the Motif toolkit will run under any window
manager.

Subject: 24)  How can I modify the Motif window manager decorations?

Answer: In resource files, use the window manager's client resource (which is
the application) and the resource clientDecoration:

Mwm*XClock.clientDecoration:   none

turns off all clock decorations.  See the mwm(1) entry for other
possibilities.

Programmatically, set the VendorShell resource XmNmwmDecorations to
appropriate values: MWM_DECOR_NONE (or a bitwise or of values).

Subject: 25)  How can I turn off the Motif window manager functions from the
system menu?
[Last modified: October 92]

Answer: The user of an application can control functions in the system menu
for an application using the mwm resource clientFunctions:

        mwm.application_name.clientFunctions: -resize -close

Note that mwm will have to be restarted after putting this in their resource
database.


Answer: The writer of an application can only remove items.  Be warned that
your users will probably gnash their teeth, swear furiously at your product
and stop using it if they discover that you have done this.  (Especially if
you have removed the Close button, your application has hung and it has taken
up all of memory and swap so it can't be killed.) Much better is to catch the
action gracefully as in the next question.

        #include <Xm/MwmUtil.h>

        XtVaGetValues(shell, XmNmwmFunctions, &int_val, NULL);
        int_val &= ~(MWM_FUNC_CLOSE | MWM_FUNC_ALL);
        XtVaSetValues(shell, XmNmwmFunctions, int_val, NULL);

Subject: 26)  How can tell I if the user has selected the "Close" item on the
system menu attached to the top-level shell?  I need to do some clean up
before exiting.

Answer:          This works with R4 Intrinsics

        void FinalCleanupCB(w, client_data, call_data)
        Widget   w;
        caddr_t  client_data, call_data;
        {
                /* tidy up stuff here */
                ...
                /* exit if you want to */
                exit (0);
        }

        main()
        {
                Atom wm_delete_window;

                ...
                XtRealizeWidget(toplevel);
                ...
                wm_delete_window =
                        XmInternAtom(XtDisplay(toplevel),
                                "WM_DELETE_WINDOW", False);
                XmAddWMProtocolCallback(toplevel, wm_delete_window,
                        FinalCleanupCB, NULL);
                XtMainLoop();
        }

This will still kill the application.  To turn this behaviour off so that the
application is not killed, set the shell resource XmNdeleteResponse to
XmDO_NOTHING.  This means that users cannot kill your application via the
system menu, and may be a bad thing.

If you are running R3, Bob Hays ([e-mail]) has suggested this:
"Trapping on the delete window atom does not work as I cannot force my action
routine to the top of the action list for the activity desired, so the window
manager kills my window anyway BEFORE I can do anything about it.  And, to
make matters worse, the window manager (Motif in this case) tacks its atoms
and handlers onto the window at some unknown point down the line after the
creation of the shell widget as far as I can tell.  So....

I have a procedure as an action routine for ClientMessage.  Then, if I get a
property change event on the window manager protocols, I then tack on
WM_SAVE_YOURSELF.  If I get this request, I clean up (it seems to happen on
WM_DELETE_WINDOW, BTW, if you remove WM_DELETE_WINDOW from the WM protocols
atom) and exit.  Works great and is less filling overall:-)."

Subject: 27)  Is there an mwm virtual desktop manager?

Answer: Peter E. Wagner ([e-mail]): Imagine that your "desktop"
extends beyond the view provided by your monitor.  A virtual window manager
gives you access to the space beyond your viewport (i.e. your screen) by
allowing you to move the viewport to other areas of the extended desktop.

The first one is Solbourne's swm, which spawned vtwm/tvtwm/olvwm.

David B. Lewis created one.  [e-mail] has further developed it
into the UniPalm product DOORS, which is only available as a source code
extension to the MOTIF window manager.  The price of the source and unlimited
right to distribute binaries is 10,000 pounds Sterling.  Alternately, source
and right to use within one company is 2,000 pounds Sterling.  Contact Peter
Dawe
