The site, in particular, is known to have much of the
contrib stuff that can be found on expo.

The release is available to DEC Easynet sites as CRL::"/pub/X11/R4".
Sites in Australia may contact this address: ftp.Adelaide.EDU.AU []
and check the directory pub/X/R4. The machine shadows expo and archives
comp.sources.x. (Mark Prior, [email protected], 5/90)

Note: a much more complete list is distributed regularly by Dan Heller
([email protected]) as part of the introductory postings to comp.sources.x.

Subject: 2)* Where can I obtain patches to X11R4?

The xstuff server now has seventeen patches for X11R4 [9/90]. Send to
[email protected] the Subject line
send fixes #
where # are numbers in the range of 1 to 17 (e.g. `send fixes 3 5 7 8 10`).

Patches are sometimes also distributed through the newsgroup
comp.sources.x, with some lagtime, and are typically archived on sites from
which X11R4 is available.

Some source re-sellers may be including patches in their source
distributions of X11R4.

Subject: 3)* Where can I obtain Motif?

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, ISC, Mips (RISCwindows=X11R3 + full Motif), IBM.

In addition, independent binary vendors produce Motif toolkits. ICS
makes several binary kits, notably for Sun, DEC, Apple; Quest (408-988-8880)
sells kits for Suns, as well; IXI (+44 223 462 131) offers kits for Sun3 (SunOS
3.5 or later, and Sun4 (SunOS 4.0.1 or later). Unipalm XTech (+44 954 211862;

Subject: 4) Where can I obtain toolkits implementing Open Look?

Sun's XView has a SunView-style API. A new version is on the X11R4
tape; version 2.0 is also available (as of 8/90) on
for anonymous ftp. Supported binaries of XView include:

AT&T's Open Look GUI 2.0 Xt-based toolkit is now generally available
[2/90]; contact 1-800-828-UNIX#544 for information. Binaries are produced
for SPARC systems by International Quest Corporation (408-988-8289). A version
of the toolkit is also produced under the name OLIT by Sun.

Sun is shipping OpenWindows 2.0 for Sparc, Sun-3, and Sun386i machines;
contact your local sales representative for more details.

Solbourne's extensible C++-based Object Interface Library will be
distributed by AT&T [date of availability appx. 6/90].

Subject: 5) Where can I obtain other X sources?
User-contributed software is distributed through the newsgroup
comp.sources.x, moderated by Dan Heller ([email protected]); also check that group
for posting information.

The machine has a great deal of user-contributed
software in the contrib/ directory; a good deal of it is present in current or
earlier versions on the X11R3 and X11R4 contrib tapes. There is a new directory
contrib/R4fixes/ for fixes to R4 contrib software. [Jim Fulton, 2/90]

The material on, which tends to duplicate
the expo archives, is also available via anonymous UUCP from osu-cis, at TB+
and V.32 speeds. Write to [email protected] (same as osu-cis!uucp) for
instructions. [the archive is now maintained by Karl Kleinpaste]

A new west-coast UUCP X11 Archive is administered by Mark Snitily
([email protected]) and contains the full X11R4 distribution, the XTEST
distribution, an entire archive of comp.sources.x and other goodies.
The machine zok has a TB+ modem which will connect to 19.2K, 2400,
1200 baud (in that order). The anonymous UUCP account is UXarch with password
Xgoodies. The modem's phone number is 408-996-8285.
A sample Systems (or L.sys) entry might be:
zok Any ACU 19200 4089968285 in:--in: UXarch word: Xgoodies
14%) To get a current listing of the files that are available, download
the file "/usrX/ls-lR.Z".
A full subject index of the comp.sources.x files is available in the
file "/usrX/comp.sources.x/INDEX".
The machine has just the one modem, so please do not fetch large
amounts of data at one sitting.

Subject: 6) What is the xstuff mail-archive?

The xstuff server is a mail-response program. That means that you mail
it a request, and it mails back the response.
Any of the four possible commands must be the first word on a line. The
xstuff server reads your entire message before it does anything, so you can
have several different commands in a single message (unless you ask for help).
23%)The xstuff server treats the "Subject:" header line just like any other line
of the message.
The archives are organized into a series of directories and
subdirectories. Each directory has an index, and each subdirectory has an
index. The top-level index gives you an overview of what is in the
subdirectories, and the index for each subdirectory tells you what is in it.

1) The command "help" or "send help" causes the server to send you a
more detailed version of this help file.
2) if your message contains a line whose first word is "index", then
the server will send you the top-level index of the contents of the archive. If
there are other words on that line that match the name of subdirectories, then
the indexes for those subdirectories are sent instead of the top-level index.
For example, you can say "send index fixes" (or "index fixes"). A message that
requests an index cannot request data.
3) if your message contains a line whose first word is "send", then the
xstuff server will send you the item(s) named on the rest of the line. To name
an item, you give its directory and its name. For example
send fixes 1 3 4
You may issue multiple send requests. The xstuff server contains many
safeguards to ensure that it is not monopolized by people asking for large
amounts of data. The mailer is set up so that it will send no more than a fixed
25%)amount of data each day. If the work queue contains more requests than the
day's quota, then the unsent files will not be processed until the next day.
Whenever the mailer is run to send its day's quota, it sends the requests out
4) Some mailers produce mail headers that are unusable for extracting
return addresses. If you use such a mailer, you won't get any response. If
you happen to know an explicit path, you can include a line like
path foo%[email protected]
path bar!foo!frotz
in the body of your message, and the daemon will use it.

The xstuff server itself can be reached at [email protected]. If
your mailer deals in "!" notation, try sending to

Subject: 7)* Where can I find books/articles on X that are good for beginners?

Ken Lee of the DEC Western Software Laboratory ([email protected])

062-522422) ...

Among the best places to find courses are at the various Unix
conferences -- Uniforum, Usenix, Unix Expo, Xhibition, the MIT X Technical
Conference, &c.

Subject: 9) Is there a skeleton X program available?

There is no general framework such as the TransSkel program for the
Macintosh which handles lots of the odds and ends and overhead of development
under a window system and which can be used as a platform for additional
development. In X, the problem is typically solved by using an interactive
application builder tool or by using cut&paste on existing X applications. Good
applications which you might look to manipulate when you want to "test just
this one little thing" include contrib/clients/xskel, a simple R4 program that
puts up a window and allows sketching in it and offers a starting point for
32%)quick hacks, the Xaw examples in the examples/ directory in the R3 and R4
distributions, and the Xlib "Hello World" example in the R3 doc/HelloWorld and
R4 doc/tutorials/HelloWorld; an updated version of this program which uses R4
Xlib calls and current ICCCM conventions was posted in 2/90 to
by Glenn Widener of Tektronix. [3/90]

Subject: 10) What are these common abbreviations?

Xt: The X Toolkit Intrinsics is a library layered on Xlib which
provides the functionality from which the widget sets are built. An "Xt-based"
program is an application which uses one of those widget sets and which uses
Intrinsics mechanisms to manipulate the widgets.
Xmu: The Xmu library is a collection of Miscellaneous Utility functions
useful in building various applications and widgets.
Xaw: The Athena Widget Set is the MIT-implemented sample widget set
distributed with X11 source since X11R2.
Xm: The OSF/Motif widget set from the Open Software Foundation; binary
kits are available from many hardware vendors
XUI: DEC's X-programmer's toolkit, including a widget set and a high-
level widget description language, is being phased out.
Xhp (Xw): The Hewlett-Packard Widget Set was originally based on R2++,
but several sets of patches exist which bring it up to R3, as it is distributed
34%)on the X11R4 tapes.
dxwm: The DECWindows window manager is part of DEC's current X release.
mwm: The Motif Window Manager is distributed with OSF/Motif source and
is available from vendors in binary form.
CLX: The Common Lisp X Interface is a Common Lisp equivalent to Xlib.
XDMCP: The X Display Manager Protocol provides a uniform mechanism for
a display such as an X terminal to request login service from a remote host.
XLFD: The X Logical Font Description Conventions describes a standard
logical font description and conventions to be used by clients so that they
can query and access those resources.
RTFM: Common expert-speak meaning "please locate and consult the
relevant documentation -- Read the Manual"
UTSL: A common expression meaning "take advantage of the fact that you
aren't limited by a binary license -- Use The Source, Luke".

Subject: 11)+ What is the ICCCM?

The Inter-Client Communication Conventions Manual is one of the
official X Consortium standards documents that define the X environment. It
describes the conventions that clients must observe to coexist peacefully with
other clients sharing the same server. If you are writing X clients, you need
to have read and understood the ICCCM, in particular the sections discussing
35%)the selection mechanism and the interaction between your client and the window
manager. Get it either:
- as part of the R4 distribution from MIT.
- in the 2nd edition of the Scheifler/Gettys "X Window System" book.
- as an appendix in the new version of O'Reilly's Volume 0, "X Protocol
Reference Manual." A version in old copies of their Volume 1 is obsolete.
The version in the DP book is much more readable, thanks to the efforts
of Digital's editors to improve the English and the presentation.

[from David Rosenthal, 10/90]

Alternate definition: The ICCCM is generally the M in "RTFM" and is
the most-important of the least-read X documents.

Subject: 12) What is XUG?

The X User's Group was formed in January of 1988. Its purpose is to
encourage X development by providing information on the X Window System to all
who are interested.

Subject: 13)* What is EXUG?

The European X User Group was formed in 1989 to represent X users in Europe.
It holds technical conferences at regular intervals.

The EXUG also publishes a regular newsletter which is distributed free of
charge to members. The EXUG also runs a email mailing list for members which
is frequently used to address issues of European interest in X.

The EXUG can be contacted by email at: [email protected] or by snail mail at:

Subject: 14) What is the X Consortium and how do I join?

The MIT X Consortium was formed in January of 1988 to further the
38%)development of the X Window System and has as its major goal the promotion of
cooperation within the computer industry in the creation of standard software
interfaces at all layers in the X Window System environment.
MIT's role is to provide the vendor-neutral architectural and
administrative leadership required to make this work. Membership in the
Consortium open to any organization. There are two categories of membership,
Member (for large organizations) and Affiliate (for smaller organizations).
Most of the Consortium's activities take place via electronic mail,
with meetings when required. As designs and specifications take shape,
interest groups are formed from experts in the participating organizations.
Typically a small multi-organization architecture team leads the design, with
others acting as close observers and reviewers. Once a complete specification
is produced, it may be submitted for formal technical review by the Consortium
as a proposed standard. The standards process typically includes public
review (outside the Consortium) and a demonstration of proof of concept.
Your involvement in the public review process or as a Member or
Affiliate of the Consortium is welcomed.
Write to: Bob Scheifler, MIT X Consortium, Laboratory for Computer
Science, 545 Technology Square, Cambridge, MA 02139.

distribution, from which this information is adapted.] [2/90]

Subject: 15) What is xpert?

The xpert mailing list is the general, public mailing list on X
maintained by the X Consortium. The mailings are gatewayed, so xpert is almost
identical to the Usenet newsgroup.

*** If you get, you don't need to ***
*** be added to the xpert mailing list. ***

Otherwise, you can join the list to receive X information
electronically. It is best to find a local distribution; perhaps someone within
your company is already receiving the mailing. As a last resort, send mail to
[email protected] with a valid return electronic address.

Subject: 29) How can I design my own font?

One way is to use the "bitmap" client or some other bitmap-editor (e.g.
Sun's icon-editor tool, post-processed with pbmplus) to design the individual
characters and then to do some large amount of post-processing to concatenate
them into the BDF format.
The R3 contrib/ area (in fonts/utils/ and in clients/xtroff) contained
a number of useful utilities, including some to convert between BDF font format
and a simple character format which can be edited with any text editor.
An easier way is to use the "xfed" client to modify an existing font; a
recent version is on the R4 tape in contrib/clients/xfed; there are older
versions on the R3 contrib tape.
Subject: 30) What is PEX?

The PHiGS Extension to X is a proposed X Consortium standard awaiting
proof of concept; PHiGS stands for "Programmer's Hierarchical Interactive
Graphics System" and is essentially a library of functions that simplifies the
creation and manipulation of 3D graphics. Many platforms are capable of
performing in hardware the computations involved in rendering 3D objects; the
server extension would allow the client (PHIGS in this case) to take advantage
of the specialized hardware for 3D graphics.
Sun Microsystems is currently contracted to develop a freely
redistributable (copyright similar to the current X copyright) sample
implementation. The current schedule calls for this implementation to be
publicly available in early 1991. Several vendors are currently selling
independently-developed PEX servers for their workstations.

Subject: 32) How do I use another window manager with DEC's session manager?

DEC's session manager will start dxwm up by default. To override this,

Subject: 33) How do I build X with gcc?

70%) MIT is now using regularly the Free Software Foundation's
GNU-CC to build the X distribution and uses gcc-built servers to test
performance increases.

[These options are gathered from several descriptions of building
X with gcc 1.34, 1.35, and 1.36]:

Use the options
-O -fstrength-reduce -fpcc-struct-return

-traditional may also be necessary if your version of
gcc is sufficiently old.

Do not use -finline-functions, particularly on the R4 server.

---> Make sure to run 'fixincludes' from the gcc distribution
---> before doing anything, or you will get fatal errors such as:
---> xterm: Error 15, errno 25: Inappropriate ioctl for device.

HOWEVER, there is a bug in gcc 1.34 and 1.36 (but not in 1.35 or 1.37) which
miscompiles things of the form (expr == 0 ? exp1 : exp2). The fix needed in
X11R4 (and probably X11R3) is to change the definition of XtNewString in
Intrinsic.h to:
71%) #define XtNewString(str) \
((str) != NULL ? (strcpy(XtMalloc((unsigned)strlen(str) + 1), str)) : NULL)
A work-around is also in fix-2 to X11R4.

Subject: 34) Why doesn't gcc work with X11R4 on my SPARC?
I used gcc to compile the whole distribution, but I get several segmentation
faults when running X.

Note first that gcc on RISC machines does not necessarily result in
any performance increase; it certainly is not as noticeable as it is on the
680x0 or VAX platforms.

Here is the problem: gcc and cc use incompatible methods of passing
structures as arguments and returning them as function values, so when
gcc-compiled parts of X are linked with Sun-supplied functions that pass or
return structs, run-time errors occur. Affected programs include rgb and
the server.

This is from the GCC manual:

On the Sparc, GNU CC uses an incompatible calling convention for
structures. It passes them by including their contents in the argument
72%) list, whereas the standard compiler passes them effectively by

This really ought to be fixed, but such calling conventions are not yet
supported in GNU CC, so it isn't straightforward to fix it.

The convention for structure returning is also incompatible, and
`-fpcc-struct-return' does not help.

You can duck the problem either by using cc throughout or by using it for just
the routines which cause incompatibilities; the problem cannot be solved with
compilation flags.

Files which need to be compiled using cc include:

In addition, several of the "init_" functions use structs as args or
return values:
Calls to inet_addr in /lib/CLX/socket.c and lib/X/XConnDis.c are possibly
harmless as they don't involve structs.

Subject: 35) What are these problems building X with gcc?
When I try to run xinit or the Xsun server I get the error
"Getting interface configuration: Operation not supported on socket.
Fatal server bug! no screens found."

Running the gcc fixincludes script apparently didn't work. You can do
this simple test:


Run that through cc -E and gcc -E. The last line of output is the piece of
interest; it should be identical (modulo irrelevant differences like
whitespace). If the gcc version has 'x' where the cc version has 'i', your
fixincludes run didn't work for some reason or other. If they are identical,
try running a make clean in mit/server and rebuilding, just to make sure
everything gets compiled with the proper include files.

Subject: 36) What are these funny problems compiling X11R3 on the Sun4?

cc -c -O -I. -I../../include -I../../.././X11 -I../mfb cfbbitblt.c
cc: Fatal error in iropt: Illegal instruction (core dumped)

Known problems with the Sun4 optimizer render the -O flag unusable
on this file.

In addition, there is a problem in all of the procedures that return a
parameter that was never referenced. Instead of returning the string, the
compiler with optimization seems to be returning the last value computed. You
can compile lib/Xt/TMparse.c without optimization; alternatively, you can
replace the "return str" in various routines to use that parameter [courtesy of
Jim Fulton, MIT X Consortium]:

* causes the value of the most recently used variable to be returned instead
* of the value passed in.

to cc should be obtained from Sun.

Subject: 37) What are these problems installing R4 on the Sun running SunOS 4?
All of the executables that I try to run have the following results: not found
or even: call to undefined procedure __GetHostname from 0xf776a96c

If you are building with shared libraries on a Sun, remember that you
need to run "ldconfig" as root after installing the shared libraries (if you've
installed X on a file-server, run it on the server's clients, too). While
building and installing the distribution, you need to be careful to avoid
76%)linking against any existing X shared libraries you might have (e.g. those
distributed with OpenWindows). You should make sure you do not have
LD_LIBRARY_PATH set in your environment during the build or the installation.
If you are going to keep xterm and xload as setuid programs, please note that
the shared libraries must be installed in /usr/lib, /usr/local/lib, or
/usr/5lib for these programs to work (or else those programs must be linked
statically). [courtesy MIT X Consortium]
Note also that the program mkfontdir is run as part of the build; it
attempts, however, to use the shared libraries before they have been installed.
You can avoid the errors by building mkfontdir statically (pass -Bstatic to
most C compilers).

Subject: 38) Why doesn't XtAppAddInput work as described?
I am using XtAppAddInput to read from a file, but the function is called even
when there isn't input pending.

XtAppAddInput is actually working as it is supposed to. When used on
files, it is called whenever the file is READY to be read, not when there is
new data to be read. The file is almost always ready to be read, however, if
only because you can spin back to the beginning and read data you've read
before. The result is that your function will almost always be called every
time around XtMainLoop().
78%) To get the type of interaction you are expecting, add this line to
the beginning of your function to test whether there is new data:
if (ioctl(fd, FIONREAD, &n) == -1 || n == 0) return;

Subject: 39) Where can I get a fast X server for a workstation?

The R4 server should be among the fastest available for most machines.

The "Purdue" speedups significantly speed up the X11R3 server. Look on[01]-tar.Z. (You'll also need gcc.)

International Quest Corporation (408-988-8289) has an optimized R3
server for Sun3/4/386i under SunOS 4.0 and also an optimized R4 server.

Unipalm XTech (+44 954 211244) makes several R3-based and R4-based
tuned servers, most notably for Sun 3 and Sun 4. (Note: the original work
was inherited from Torch Technology.)

Xgraph's Xtool (408-492-9031) is an X server implemented in SunView
which boasts impressive results on Sun 3 and SPARC systems. [6/90]
Several companies are making hardware accellerator boards:

Dupont Pixel Systems (302-992-6911), for Sun.

Megatek's (619-455-5590) X-cellerator board for the Sun 3 and Sun 4 is
based on the TI 34020; the company claims performance improvements of 5x to
10x over the sample X11R3 server.

Subject: 40) Where can I find X tools callable from shell scripts?
I want to have a shell script pop up menus and yes/no dialog boxes if the user
is running X.

Several tools in the R3 contrib/ area were developed to satisfy these
needs: yorn pops up a yes/no box, xmessage displays a string, etc. There are
several versions of these tools; few, if any, have made it to the R4 contrib/
area, though they may still be available on various archive sites.
In addition, Richard Hesketh ([email protected]) has posted the xmenu
package to comp.sources.x ("v08i008: xmenu") for 1-of-n choices.

80%)Subject: 41)* How do I make a screendump of the X display?

The xwd client in the R3 and R4 distributions can be used to select a
window or the background. It produces an XWD-format file of the image of that
window. The file can be post-processed into something useful or printed with
the xpr client and your local printing mechanism. You can use this command:
csh% sleep 10; xwd -root > output.xwd &
and then spend 10 seconds or so setting up your screen; the entire current
display will be saved into the file output.xwd. Note that xwd also has an
undocumented -id flag for specifying the window id on the command-line.

Two publicly-available programs which allow interactive definition of
arbitrary portions of the display and built-in delays are asnap and xgrabsc.
Xgrabsc was both recently [8/90] posted to comp.sources.x; asnap is on expo.
In addition, xwd2ps, also on expo, converts an xwd-format file to PostScript
with trimmings suitable for use in presentations.

Also: some vendors' implementations of X (e.g. DECWindows and
OpenWindows 2.0) include session managers or other desktop programs which
include "print portion of screen" or "take a snapshot" options.

Also: some platforms have tools which can be used to grab the
frame-buffer directly. The Sun systems, for example, have a 'screendump'
81%)program which produces a Sun raster file. PBMPLUS or other packages can be used
to massage the output into a useful format.

Also: some vendors' implementations of lpr (e.g. Sony) include direct
support for printing xwd files.

Subject: 42) How can I change the titlebar of my xterm window?

The solution involves sending an escape sequence to xterm which will
cause it to update the property which the window manager relies upon for the
string which appears in the window titlebar.
A solution is as easy as typing this in an xterm running a shell:
echo "ESC]2;TEXT^G"
where ESC is the escape key, TEXT is the string you wish to have displayed,
and ^G is a Control-G (the BEL character).

Here is a more complicated csh alias which changes the titlebar to
the current working directory when you change directories:
alias newcd 'cd \!* ; echo ESC]2\;$cwd^G'

The digit '2' in these strings indicates to xterm that it should
change only the title of the window; to change both the title and the name
82%)used in the icon, use the digit '0' instead, and use '1' to change only the
icon name.

These sequences work for both R3 and R4 xterm windows; the R4 xterm,
however, does not accept the looser sequences which worked under R3 and
demands a semicolon, above, for example, where the R3 xterm allowed any

[For more information, see the article by Skip Montanaro of GE CR&D on Xterm
control sequences in the December 1989 XNextEvent.]

Subject: 43) Why doesn't anything appear when I run this simple program?

> ...
> the_window = XCreateSimpleWindow(the_display,
> root_window,size_hints.x,size_hints.y,
> size_hints.width,size_hints.height,BORDER_WIDTH,
> BlackPixel(the_display,the_screen),
> WhitePixel(the_display,the_screen));

> ...
> XDrawLine(the_display,the_window,the_GC,5,5,100,100);
> ...

You are right to map the window before drawing into it. However, the
window is not ready to be drawn into until it actually appears on the screen --
until your application receives an Expose event. Drawing done before that will
generally not appear. You'll see code like this in many programs; this code
would appear after window was created and mapped:
while (!done)
switch (the_event.type) {
case Expose: /* On expose events, redraw */

Note that there is a second problem: some X servers don't set up the
default graphics context to have reasonable foreground/background colors, and
84%)your program should not assume that the server does, so this program could
previously include this code to prevent the case of having the foreground and
background colors the same:
the_GC_values.foreground=BlackPixel(the_display,the_screen); /* e.g. */
the_GC_values.background=WhitePixel(the_display,the_screen); /* e.g. */
the_GC = XCreateGC(the_display,the_window,

Note: the code uses BlackPixel and WhitePixel to avoid assuming that 1 is
black and 0 is white or vice-versa. The relationship between pixels 0 and 1
and the colors black and white is implementation-dependent. They may be
reversed, or they may not even correspond to black and white at all.

Subject: 44) What is the difference between a Screen and a screen?

The 'Screen' is an Xlib structure which includes the information about
one of the monitors or virtual monitors which a single X display supports. A
server can support several independent screens. They are numbered unix:0.0,
unix:0.1, unix:0.2, etc; the 'screen' or 'screen_number' is the second digit --
the 0, 1, 2 which can be thought of as an index into the array of available
86%)Screens on this particular Display connection.
The macros which you can use to obtain information about the particular
Screen on which your application is running typically have two forms -- one
which takes a Screen and one with takes both the Display and the screen_number.
In Xt-based programs, you typically use XtScreen(widget) to determine
the Screen on which your application is running, if it uses a single screen.
(Part of the confusion may arise from the fact that some of the macros
which return characteristics of the Screen have "Display" in the names --
XDisplayWidth, XDisplayHeight, etc.)

Subject: 45) How do I determine the name of an existing widget?
I have a widget ID and need to know what the name of that widget is.

R4 users are best off using the XtName() function, which will work
on both widgets and non-widget objects.

If you are still using R3, you can use this simple bit of code to do
what you want. Note that it depends on the widget's internal data structures
and is not portable to future versions of Xt, including R4.

String XtName (widget)
87%) Widget widget; /* will not work with non-widget objects */
return widget->;


Subject: 46) Why do I get a BadDrawable error drawing to XtWindow(widget)?
I'm doing this in order to get a window into which I can do Xlib graphics
within my Xt-based program:

> canvas = XtCreateManagedWidget ( ...,widgetClass,...) /* drawing area */
> ...
> window = XtWindow(canvas); /* get the window associated with the widget */
> ...
> XDrawLine (...,window,...); /* produces error */

The window associated with the widget is created as a part of the
realization of the widget. Using a window id of NULL ("no window") could
create the error that you describe. It is necessary to call XtRealizeWidget()
before attempting to use the window associated with a widget.
Note that the window will be created after the XtRealizeWidget() call,
88%)but that the server may not have actually mapped it yet, so you should also
wait for an Expose event on the window before drawing into it.

Subject: 47) Can XGetWindowAttributes get a window's background pixel/pixmap?

No. Once set, the background pixel or pixmap of a window cannot be
re-read by clients. The reason for this is that a client can create a pixmap,
set it to be the background pixmap of a window, and then free the pixmap. The
window keeps this background, but the pixmap itself is destroyed. If you're
sure a window has a background pixel (not a pixmap), you can use XClearArea()
to clear a region to the background color and then use XGetImage() to read
back that pixel. However, this action alters the contents of the window, and
it suffers from race conditions with exposures. [courtesy Dave Lemke of NCD
and Stuart Marks of Sun]

Note that the same applies to the border pixel/pixmap. This is a
(mis)feature of the protocol which allows the server is free to manipulate the
pixel/pixmap however it wants. By not requiring the server to keep the
original pixel or pixmap, some (potentially a lot of) space can be saved.
[courtesy Jim Fulton, MIT X Consortium]

89%)Subject: 48) Why does the pixmap I copy to the screen show up as garbage?

The initial contents of pixmaps are undefined. This means that most
servers will allocate the memory and leave around whatever happens to be there
-- which is usually garbage. You probably want to clear the pixmap first using
XFillRectangle() with a function of GXcopy and a foreground pixel of whatever
color you want as your background (or 0L if you are using the pixmap as a
mask). [courtesy Dave Lemke of NCD and Stuart Marks of Sun]

Subject: 49) Why doesn't my program get the keystrokes I select for?

The window manager controls how the input focus is transferred from one
window to another. In order to get keystrokes, your program must ask the
window manager for the input focus. To do this, you must set up what are
called "hints" for the window manager. If your applications is Xlib-based, you
can use something like the following:

XWMHints wmhints;
wmhints.flags = InputHint;
wmhints.input = True;
XSetWMHints(dpy, window, &hints)

If your application is based on the Xt Intrinsics, you can set the XtNinput
resource to be True (as you probably want to in any case); if you don't have
source, you can start up the application with the resource '*input:True'.

Certain window managers, notably dxwm and olwm, are very picky about having
this done.

If you are using Sun's OpenWindows olwm, you can also add this resource
to your defaults file to use clients that aren't ICCCM-compliant.
OpenWindows.FocusLenience true

[mostly courtesy Dave Lemke of NCD and Stuart Marks of Sun]

Subject: 50) How can my application iconify itself?

The ICCCM provides a mechanism for this; your application sends a
client message which includes a data value indicating that it wishes to be
iconified. Here is a sample callback that will iconify the application shell,
wait 3 seconds, and pop it back up. Note that ApplicationShellWidget below
is global; it would make more sense in real use to walk up the tree via
92%)XtParent() to find the shell containing the active widget.

void IconifyShell(w, d1, d2)
Widget w;
caddr_t d1, d2;
XClientMessageEvent event;
Window win;
Display *dpy;

event.type = ClientMessage;
event.send_event = True;
dpy = event.display = XtDisplay(w);
win = event.window = XtWindow(ApplicationShellWidget);
event.message_type = XInternAtom(dpy, "WM_CHANGE_STATE", False);
event.format = 32;[0] = IconicState;
XSendEvent(dpy, DefaultRootWindow(dpy), False,
SubstructureRedirectMask | SubstructureNotifyMask, &event);
[courtesy David Brooks ([email protected]), 4/90]

R4 users may find it easier to use this routine:

* This function instructs the window manager to change this window from
* NormalState to IconicState.
Status XIconifyWindow (dpy, w, screen)
Display *dpy;
Window w;
int screen;

Subject: 51) How do I check whether a window ID is valid?
My program has the ID of a window on a remote display. I want to check whether
the window exists before doing anything with it.

Because X is asynchronous, there isn't a guarantee that the window would
93%)still exist between the time that you got the ID and the time you sent an
event to the window or otherwise manipulated it. What you should do is send
the event without checking, but install an error handler to catch any BadWindow
errors, which would indicate that the window no longer exists. This scheme
will work except on the [rare] occasion that the original window has been
destroyed and its ID reallocated to another window.

[courtesy Ken Lee ([email protected]), 4/90]

Subject: 52) Can I have two applications draw to the same window?

Yes. The X server assigns IDs to windows and other resources, and any
application that knows the ID can manipulate the resource.
The problem you face is how to disseminate the window ID to multiple
applications. A simple way to handle this (and which solves the problem of the
applications' running on different machines) is in the first application to
create a specially-named property on the root-window and put the window ID into
it. The second application then retrieves the property, whose name it also
knows, and then can draw whatever it wants into the window.
[Note: this scheme works iff there is only one instance of the first
application running, and the scheme is subject to the limitations mentioned
95%)in the Question about using window IDs on remote displays.]
[Note also that you will still need to coordinate any higher-level
cooperation among your applications.]

Subject: 53) Why can't I set the backgroundPixmap resource in my defaults file?
I want to be able to do something like this:
xclock*backgroundPixmap: /usr/include/X11/bitmaps/rootweave

You can't do this. The backgroundPixmap resource is a pixmap of the
same depth as the screen, not a bitmap (which is a pixmap of depth 1). Because
of this, writing a generic String to Pixmap converter is impossible, since
there is no accepted convention for a file format for pixmaps. Therefore,
neither the X Toolkit or the Athena widget set define a String to Pixmap
converter; because there is no converter you cannot specify this value as a

The Athena widget set does define a String to Bitmap converter for use
in many of its widgets, however.

[courtesy Chris D. Peterson ([email protected]), 4/90]
[Note: the leading general-purpose format for pixmaps is the XPM format
used by Groupe Bull in several of its programs, including the GWM window
manager, by AT&T in its olpixmap editor, and by ICS in its interface builder.
XPM is being now handled by Richard Hess ([email protected]). The
XPM distribution, available on expo as contrib/xpm.tar.Z, includes read/write
routines which can easily be adapted to converters by new widgets which want
to allow specification of pixmap resources in the above manner.]

Subject: 54) Why does the R3 xterm, et al, fail against the R4 server?

The value given to a window's do_not_propagate mask is the likely
culprit. R3 allowed bogus values to be set, and early version of both Andrew
and Interviews did, as well. Similar problems also occur in the R3 Motif
PanedWindow widget.

If it is impossible to fix client source, use 'xset bc' to put the
X11R4 server into bug-compatibility mode.

Subject: 55) Does Motif 1.0 work with X11R4?

97%) Applications based on OSF/Motif 1.0 will run against an R4 server if it
is set to bug-compatibility mode or if a patch (part of the 1.0.3 upgrade) to
the XmPanedWindow is obtained.

Applications based on OSF/Motif 1.0 can be built or linked on a system
with X11R4 libraries provided that the Motif version of the R3 Intrinsics is
used; the R4 Xt should not be used with Motif 1.0 programs.

Motif 1.1, available in source form from OSF in August, uses the
"vanilla" X11R4 Intrinsics, where "vanilla" means "with just a few patches from
MIT and some more from OSF".

Subject: 56) Where can I obtain alternate language bindings to X?

Versions of the CLX Lisp bindings are part of the X11R3 and X11R4 core
source distributions. The latest version of CLX (R4.3) is available from expo
for ftp as contrib/CLX.R4.3.tar.Z; this version fixes bugs reported against
the R4 distribution.
