Time-stamp: <00/05/15 23:33:49 friedel>
(Note: don't get confused, the dates in this file are in german-locale (de_DE),
because i was too lazy to use something else than
ctrl-u meta-! date... but the timestamp is in C locale...)
0.6.1: <Mon Mai 15 23:15:29 CEST 2000>
Fixed eternal loop under openwindows (solaris-x86)
<Mon Mai 15 23:14:54 CEST 2000>
Added wmswallow.spec for easy building of rpm :-)
<Fre Mai 12 15:50:12 CEST 2000>
0.6: <Fre Mai 12 02:16:30 CEST 2000>
Celebrated first wmswallow version without my favorite bug, with a beer :-)
Made the switches work :-)
<Fre Mai 12 01:49:49 CEST 2000>
Added commandline switches -managed -unmanaged. -managed is the default
behaviour, we wait for the Window to be reparented.
<Fre Mai 12 01:27:47 CEST 2000>
Added code from Jason Lowdermilk to listen to CreateWindow Events, after the
app has been started. Then i modified it heavily, because i found it was still
too unreliable. Now wmswallow Listens for ReparentNotify events. So, we rely
on WindowMaker first reparenting the windows, then sleep just a second and can
be sure that everything worked! And i don't think that the Windowmaker
behaviour (or any other windowmanager) will change in that respect :-) Well,
this might not work for xteddy (or other apps that are ignored by the
windowmanager)
<Fre Mai 12 00:47:24 CEST 2000>
Put code to check window for WM_CLASS and WM_NAME in extra function.
<Don Mai 11 17:23:13 CEST 2000>
0.5.3: <Don Mai 11 01:02:02 CEST 2000>
Fixed a nasty bug that i introduced by modyfying Jason's patch incorrectly and
some tiny cleanups.
<Don Mai 11 00:54:38 CEST 2000>
Added thanks to the contributors to README
<Don Mai 11 00:29:55 CEST 2000>
Incorporated patch from Jason Lowdermilk <lowdermilk@visto.com> to enable
finding windows by WM_NAME (i confused WM_NAME with the name part of the
property returned by XGetClassHint. The patch fixes some memory leaks as well.
Jason says, this helps with some Java-Applications.
<Don Mai 11 00:10:50 CEST 2000>
0.5.2: <Mit Mai 3 22:03:27 CEST 2000>
Modified README
New switch: -focus/-nofocus, to make focus-handling enabled only on demand,
more fixes to focus-handling (this time for real...)
<Mit Mai 3 21:52:29 CEST 2000>
Small code cleanups, fixes for focus handling (windows could "lose" focus)
<Mit Mai 3 07:24:09 CEST 2000>
Keyboard focus works now.
<Die Mai 2 22:35:58 CEST 2000>
Makefile modified, new target xfree tested under linux and freebsd
<Die Mai 2 14:00:46 CEST 2000>
0.5.1: <Sam Apr 29 13:15:27 CEST 2000>
softenwindows() is superfluous, removed
chidren_return is now XFree'd in findnamedwindowacc()
0.5: <Fre Apr 28 10:30:00 CEST 2000>
Initial beta release, all functionality present, some small bugs, some small
shortcomings.
Shortly after freshmeat announcement i discovered a small bug in the Makefile,
but that was fixed before the news got out.

INSTALLATION:
+++++++++++++
untar the sources by typing something along the lines of
zcat wmswallow.tar.Z|tar cvf -
cd wmswallow
make <platform>
where platform is currently one out of
xfree, solaris, solaris-gcc
The xfree target works under linux and freebsd.
Linux is tested best, since i'm hacking this stuff under linux (at
home). I have access to several Solaris Workstations (some sparcs, and
2 pcs) whith quite different Installations which i regularly use, so
the solaris target will at least get some attention. Solaris users
please read README.solaris for some hints.
Other Unices might or might not get happy with the xfree target or
some or other... I really think using autoconf/automake for this small
app would be overkill. If you devise a proper patch for a different
Unix-flavour, i will include it, but i might not be able to test it.
(I have currently access to FreeBSD and AIX, in addition to my
"home-platforms")
After compilation put the binary somewhere you like (e.g. in /usr/local/bin)
and in case you want to delete the Sourcetree, you might want to copy the
README to /usr/doc/wmswallow
Now try
wmswallow -h
to get a basic idea how it works.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

wmswallow
A WindowMaker dock applet to make any application dockable.
Copyright 2000 by Friedrich Delgado Friedrichs
(be sure to read the LICENCE file as well)
===========================================================================
Why?
----
I wanted to have coolmail in my Windowmaker dock.
How?
----
INSTALLATION:
+++++++++++++
untar the sources by typing something along the lines of
zcat wmswallow.tar.Z|tar cvf -
cd wmswallow
make <platform>
where platform is currently one out of
xfree, solaris, solaris-gcc
The xfree target works under linux and freebsd.
Linux is tested best, since i'm hacking this stuff under linux (at
home). I have access to several Solaris Workstations (some sparcs, and
2 pcs) whith quite different Installations which i regularly use, so
the solaris target will at least get some attention. Solaris users
please read README.solaris for some hints.
Other Unices might or might not get happy with the xfree target or
some or other... I really think using autoconf/automake for this small
app would be overkill. If you devise a proper patch for a different
Unix-flavour, i will include it, but i might not be able to test it.
(I have currently access to FreeBSD and AIX, in addition to my
"home-platforms")
After compilation put the binary somewhere you like (e.g. in /usr/local/bin)
and in case you want to delete the Sourcetree, you might want to copy the
README to /usr/doc/wmswallow
Now try
wmswallow -h
to get a basic idea how it works.
USE:
++++
Then some things you might try out are:
(i.e. lots of)
EXAMPLES:
=========
------- wmswallow coolmail coolmail
(Will make coolmail docked, but it starts an xterm with mailx
per default so you will probably want:)
------- wmswallow coolmail coolmail -e "xterm -n mutt -T mutt -e mutt"
------- wmswallow glbiff glbiff
(glbiff is really a killer! Try it! (If you have some 3D
hardware) :-) Find it at
http://www.dgp.toronto.edu/~mac/projects/glbiff.html
------- wmswallow asclock asclock -shape -exe plan
(Works with the unpatched "classic" version of asclock)
------- wmswallow oclock oclock -transparent -minute red -bd green
(is one of my personal favorites)
------- wmswallow tuXeyes tuXeyes --puppy
(a nice alternative to xeyes)
------- wmswallow Lament /usr/local/bin/demos/lament -name Lament -geom 55x57
(/usr/local/bin/demos is where my xscreensaver demos are
installed.
This commandline demonstrates two things:
1. You can give a WM_CLASS on the commandline instead of a WM_NAME
2. Some applications don't handle resizing well and must get the correct
geometry on their commandline, which is always 55x57 for dockapps.)
------- wmswallow xaos xaos
(This kinda obsoletes wmmand :-)
------- wmswallow xload xload -nolabel -hl LightSeaGreen -fg LightSeaGreen \
-bg black -update 5
(This is like wmload, but there is a frame at the edges which is a
little annoying, so wmload is a better choice)
------- wmswallow -focus XTerm
(Weeelll...
1. wmswallow can swallow apps without starting them
2. it takes the first it gets
3. swallowed apps can take keyboard focus now! (Is that useful? I doubt
it, but i could not resist :-))
------- wmswallow -geom 64x64 -getclick "xterm -e top" xeyes xeyes
(A more advanced example. The xeyes look better with 64x64 than
with the default width/height of 55x57, and since xeyes ignores
mouseclicks, we can grab them and execute an xterm on a click.
Note that you must poke xeyes right in the eye! :-)
------- wmswallow -noshape -getclick gtop -geom 57x57 xload xload -nolabel \
-hl LightSeaGreen -fg LightSeaGreen -bg black -update 5
(This looks and behaves a little more like wmload. Executes
the "Gnome Systemmonitor" on a mouse click. The -noshape
option lets wmswallow ignore any shape the application might
have. I thought this would increase performance for some
apps, but it doesn't. [It just uses a very slight bit less
memory])
------- wmswallow -unmanaged xteddy xteddy
(swallows the left ear of an xteddy, that will complain about it...
completely useless :-)
------- wmswallow -focus bb xterm -bg black -fg white -T bb -fn "-*-*-*-*-*-*-2-*-*-*-*-*-*-*" -geometry 50x25 -e bb -driver curses
(utterly useless as well! :)
How not?
--------
When should you *not* use wmswallow?
- In general, if a special dockapp for that purpose already exists, you
should use it, because every instance of wmswallow has a memory
footprint of about 600k, and a simple dockapp usually uses less
ressources. If the WindowMaker developers will one day choose to
implement "swallowing" applications as a feature in the WindowMaker
dock, this will probably a much more simple and clean solution.
- You should not swallow applications over slow network links.
First tests show, that 2 mbit/s are more than enough, but 90kbit/s get
terribly hogged if you run wmswallow on a remote hosts over such a
link. Note that i am not referring to your hardware, but to the
overall throughput that can be acchieved between the two hosts.
Have a lot of fun... :-)
Thanks

The following people helped and/or contributed to wmswallow:
Dan Piponi <dan@mvfx.com>:
Makefile fix for FreeBSD
Jason Lowdermilk <lowdermilk@visto.com>:
diff to enable wmswallow really to look after the WM_NAME of a
window.
Valuable suggestions and code on how to identify the wanted
window more reliably.
further valuable input
honx:
Giving me the idea to wmswallow, by constantly nagging that
WindowMaker cannot swallow apps :-) Next thing to satisfy this
dude, somebody will have to write a pager for WindowMaker
(like the one for fvwm) that works *without* gnome... Somebody
else will have to do that, since i don't like Pagers :-)

Whew! You really want this stuff to run under solaris, huh?
Well, you can try "make solaris" if you have got sun-workshop, if you use gcc
"make solaris-gcc" *might* work. The Problem is, everybody installs libXpm in
a different place. If you know that your sysadmin put everything that is X11
related into, say, /usr/X11, the default targets will work. But if libXpm
resides in /usr/local/lib you might help yourself with:
make SOLX=/usr/local solaris
If all fails, you will have to look at the solaris target and adjust the
variables INCLUDES and LIBPATHS to help the compiler find the includes and
libs.
I also noticed that on one machine wmswallow appeared to generate constant
network load (when i was using it over a remote link) so be aware of problems.

TODO:
Bugs:
-------------
Feature-wishes:
-----------------------
detect automatically if a window wants to be managed or not (should be
easy, but the -unmanaged switch works well, too)
Kill apps nicely when killed. (Some signal handling)
Make wmswallow not only accept mouseclicks on ButtonPress, but also get
some contents of the cutbuffer on (say) a middleclick, and then do
something user-defineable about it. (generic solution for wmnetselect
stuff)
Write manpage
Maybe write freebsd port
Do things reliably/the clean way
-> I mean, don't wait for some microsecs, when you can ask the app
what's up -> find out how! -> XSync seems to work...
-> Wait a second at the right moment helps some things greatly!
Still i don't know if it's the "right thing"[TM]
Problems (maybe unresolvable):
--------------------------------------
WindowMaker segfaults if an instance of wmswallow hangs when
the wm is restarted -> Probably windowmaker bug, but can be fixed by
better signal-handling on behalf of wmswallow
If you swallow apps on the clip *and* in the dock at the same time,
the apps for the clip wander to the dock and vice versa...
Huh? This is most strange. I fear that looks like one of
WindowMaker's many bugs.. :) (Yeah, blame it on others, good
strategy!)
Shaped apps that change their shape will look "out of sync". This is
especially visible with
wmswallow xdaliclock xdaliclock -24 -transparent -cycle \
-geometry 61x61 -fn fixed -oink-oink
There are other problems with xdaliclock -transparent (flicker, the
seconds are lagged behind respectively out of beat) which do not
depend on wmswallow and can be noticed as well, when
xdaliclock -transparent is not being swallowed.
perfmeter objects to have its mouseclicks selected
-> As a workaround, i make the XInputSelect Mask dependant on
whether the user wants to click on the window, or not. But
i'd like to do it better (i.e. force perfmeter to accept
the change)
-> In fact, for every application that selects ButtonPress
events, the same events cannot be selected twice (manpage
of XSelectInput(3))
-> It seems, this "Problem" cannot be fixed!
click works only on the surface of the swallowed window:
(Obviously, because the rest of the area belongs to the
dock... Or can that be redeemed?)
===============================================================================
DONE:
Make basic dockable App
Then steal code off fvwm2 to learn how to swallow stuff
-> done.. Wow! That's easy!
Resize swallowed window appropriately
Judge what to get by following rule:
1. name
2. class
Get command to run from commandline and spawn program.
Somehow handle shaped windows (Like xeyes)
-> Ok, even resizing works
Option: -updateshape (or similar) for apps that change their shape
(like oclock -transparent)
-> is done by default behaviour! :-)
Clean up allocated space (fix memory holes)!
-> Looks ok now. Sending multiple Events under X11 has evil
effects!
Better command-line switch handling. Following commandline-switches:
-noshape/-shape : Switch shape functionality on or off
-getclick: Define commandline to exec when window is clicked
-geometry: Define geometry of swallowed application!
(Size is useful, position as well, to adjust asclock)
-id: Give Window-id to swallow
Freshmeat announcement
Let apps take keyboard focus
-> might or might not be a problem with windowmaker/dock
-> It wasn't... :-) wmMand used Enter and Leave events and then set
the focus for himself. And i blatantly stole the code... (just
2 lines...) :-)
The currently focused window flickers, when the shape gets updated.
This is especially strong with
wmswallow xdaliclock xdaliclock -24 -transparent -cycle \
-geometry 61x61 -fn fixed -oink-oink
This also interferes with focus, and it can be seen that the shape
gets updated in an unclean way, i.e. the shape and the graphics seem
"out of sync"
-> Action on Focus event shortened, XMapSubwindows and XMapWindow
weren't necessary, stealshape only grabs the shape to the
iconwin
Swallowing sometimes is unreliable (especially on WindowMaker start
with many instances) ... Why?
-> Theory: Maybe when several instances of wmswallow start,
the tree of windows gets changed in a way that sometimes a
window cannot be found anymore.
-> Jason helped a little, i figured the rest out... every
windowmanager reparents windows, and waiting for that is
very reliable...
-> done!
some apps cannot be found (xmountains). Why? xmountains in particular
seems to lack a window-id. I didn't know that was possible...
-> resolved by Jason, i did not really check the WM_NAME
just made an rpm specfile

#Patch: %{name}-%{ver}.patch
%description
- wmswallow was mainly created to swallow coolmail in the WindowMaker dock, but it can
swallow about any X-window you conceive.
- The window may receive mouseclicks,
- for windows that do not get mouseclicks (like xload or xeyes), you can specify a
shell-command to execute on a click.
- The geometry for the swallowed app can be specified. Only HEIGHTxWIDTH are used,
however.
- Applications can be started on wmswallows commandline. An already running window
can be swallowed, either by name, class or directly by window-id
- The window may receive keyboard-focus, if you specify the "-focus" switch.
- Even windows (like xteddy or wine) that hide from the windowmanager can be
swallowed with the -unmanaged switch
