Hi-
   Before I go off and do this myself, I thought I'd ask...

   Has anybody put together a package of WOOL code for gwm that would give you
a menu that is a grid of buttons instead of one long list? I've got an xterm
menu that has a button for each host. That one is getting awfully long. I'd
like to be able to do it as a 5x6 grid instead of one 30 item menu. I'm
already playing some games in constructing the menu from xterm-list, so I
could put it in there, but I wanted to see if anyone's done this one before.

Thanx,

What happened with your Oracle installation?

I've installed and administered two large Oracle databases on Sun equipment.
Both installations went smoothly and I have few problems keeping the
respective databases up.

I think that Oracle seems to be able to comp up, shut down, and recover
from disk failures fairly smoothly

Hi,

is there anybody who can tell me how I can call a function whenever the
returnkey is pressed within a dialog widget window. I had some tries with
accelerators an translations, but it doesn't work. Any hints are appreciated.
I am not on this list, I will read the answers through the comp.windows.x

In order to have a danish keyboard mapping (several additional
characters) I want to use the right ALT key Alt_R as mod3.
I have defined an xmodmap inputfile and afterwards xmodmap
returns the expected mapping, but  pressing the Alt_R key
seems to have no effect for xterm. Even Xev does not show the
expected characters, it shows a state value which is different
when the Alt_R key is pressed, but the character from XLookupString
corresponds to the character without the Alt_R pressed.
Is any special actions to be taken to have the mod3 working?
Have I overlooked something?

Best regards

I am trying to build an executable staticly so I can distribute an application
to machines without the libraries installed.  Unfortunately, when I link I
get the following undefined symbols:

_dlsym
_dlopen
_dlclose

Now I know these calls are in -ldl; however, there is no /usr/lib/libdl.a on
our system.  Only a .so, which makes it impossible to link this library in
staticly.

I tracked this down far enough to see that these symbols are being referenced
from libc.a, specifically in the mblib.o, mbstowcs.o, mbtowc.o, wcstombs.o,
and the wctomb.o modules.

I have a few questions about this:
1. Why would these modules make references to the dynamic librarie?
2. If I link adding "-Bdynamic -ldl -Bstatic" will I run into problems
   on the other machines?

I finally got together everything I thought I needed to get the

Background:

3B2/400 running SysV.3.2 with TCP/IP 3.0.
X server on Sun-3/60 running SunOS 4.1.1 and OpenWindows 2.0

I'm trying to run xlogo (or any of the other clients) on Gagme (the 3B2)
and setting the DISPLAY to serveme:0 (the Sun), but it doesn't work:

(greg@gagme /usr2/greg/bin> xlogo -display serveme:0
XIO:  fatal IO error 0 (Error 0) on X server "serveme:0.0"
      after 2 requests (2 known processed) with 0 events remaining.

What does this error message mean?  I flipped through the O'Reilly
books and couldn't find a reference to this error message.

Thanks.

I've seen statements like this before, to me it looks like that all the
people who are blaming about sendmail never made an attempt learning about
it. From my point of view, sendmail is a complex, powerful tool and
therefor it seems very natural that it's configuration is complex too.
In a complex environment and once you know what you have to do, sendmail
does it's job probably better than most of the other mailers. If you don't
know what to do - it's not sendmail's fault !

         Just MHO,

User Interface to be Motif compliant. Right now we are trying to

efforts. How helpful are UIF builders outside of the prototyping
realm? What suggestions/ideas are out there with regard to

there any good tools or development environments that significantly
aid the development of X based user interfaces for C++ applications??  

Any suggestions/thoughts/ideas would be greatly appreciated,

Hello out there,

I want to animate a sequence of about 50 pictures of simple x-y plots
under preferably X, possibly dos. Usually I use mathematica for that
purpose, but its animation program breaks on more than about 20
pictures. Since I would prefer to run the animation on my 486 running
Dells SVR4 and X and I want it to run smoothly I guess I'll have to
use something that doesn't animate bitmaps, but draws the plots line
by line. 

Any information on existing public domain animation programms of the
above kind and on programs that animate bitmaps (imported as gif, xdm,
postscript (would be great for mathematica output) or whatever) as
well as where to get them would be highly appreciated.

	In the current incarnation of Xt the order is pretty
well known.  But in would be a very bad practice to depend on this
order IMHO.  There is a reference someplace in the original Xt 
documentation that flat out states that the order callbacks are
invoked is undefined.

This is the problem: we have a Decstation 3100 with Ultrix 4.1.
We tried installing the program 'fep', which facilitates command line
editing with programs that don't allow it themselves. The program
compiles and runs without trouble, but sometimes refuses to run at all
because of a 'permission denied' error. This seems to be because for
some reason 'dxterm' seems to leave the /dev/ttyp? files with privileges
620 when exiting, while other programs, such as xterm, leave them with 666.
Is this normal behaviour and how might we work around our problem? Perhaps
someone has a working fep or might even suggest another program?

This is a recurring Intrinsics question and the answer is in the 
documentation for XtDestroyWidget, so please read it and think about it.

The following was authored by Swick and Asente:

  When you call XtDestroyWidget from within a procedure called as a result
  of event dispatching -- i.e. an event handler, an action procedure, or
  any procedure called from one of these, including callbacks -- the widget
  is marked as being destroyed but is not actually destroyed.  This prevents
  the widget data structures from disappearing out from under the event
  dispatcher, and allows applications to execute callback procedures and
  action procedures without having to worry about data structures 
  disappearing from underneath them.  When the current event dispatch is
  complete, the widgets are actually destroyed.  This includes calling
  their XtNdestroyCallback callbacks and their Destroy procedures.
