SetUp: Sun 3/80, SunOS 4.0.3, X11R4 (compiled with cc)
I am attempting to convert a fairly simple SunView program for use
under X11R4, using XView. I retrieved the latest patches I could find
from expo and applied them and compiled the XView libraries and
installed the headers as instructed. I then (FOUR HOURS LATER) ran
the convert_to_xview script and edited the resulting file which I then
compiled with the command:
cc -o ljack ljack.c -lxview -lX11 -I/usr/global/include/X11
The program compiles without error, and even runs correctly...almost.
The problem occurs when the window is iconified and the program
attempts to change the icon (This program monitors several log files
and changes the icon when an entry is made in one of the logs); the
icon does not change and cannot be de-iconified by simply clicking on
the icon, I must choose the (de)-iconify entry in my TWM menu and
click on the icon. The window will then pop up, which the latest
entry appearing in the monitored log file, but the icon also remains
on the screen. When I re-iconify the window, it goes back to the
previously frozen icon, but I can now open the window again by
clicking on the icon (until of course, the program tries to change it
again). I have found this behavior in other programs (i.e. contool)
that I have tried to convert to XView, that try to change the icon.
I think I can rule out window manager problems, as this occurs with
uwm and gwm, as well as twm.
If anyone can shed some light upon my problem, I would greatly
appreciate it.
Thanks in Advance,
Emmett

I don't think you necessarily can rule out window manager problems; you may just be dealing with three broken window managers. The X11R4 "twm"s handling of the icon window hint is *definitely* broken, and at least some of the problems you list sound like the problems it exhibited when I asked the XView "shelltool" to change its icon - it basically doesn't properly claim ownership of the new icon window. See my recent posting of a fix to it. The icon window handling of the others may be broken as well (or, in the case of "gwm", the Turing-Complete Window Manager, it may be that whatever LISP code is handling that is broken).

I believe this is a twm limitation pointed out by someone else on this alias. There's even a fix for it I believe... Regards, Heather

>I believe this is a twm limitation pointed out by someone else on this >alias. There's even a fix for it I believe... As the "someone else", I note that: 1) yes, this is a "twm" limitation - it doesn't handle IconWindowHint correctly and 2) there is a fix, in the article that noted the problem - article ID "<2881@auspex.auspex.com>". (I note you said "alias"; do you read this as a mailing list? If so, you have my sympathy; even with "tn", it's a pain to keep up. I hope the original poster doesn't read it as a mailing list, since if so it may be hard for them to dig up said article....)
