#          was used as the basis.
# *****************************************************************************

Note: I am no longer supplying patches, since this is a patch to my
      last patch.  I also am aware of several people who have made
      changes themselves.  The full directory makes the most sense.

I am assuming you rename the FvwmTaskBar that comes with fvwm95-2.0.43a
to be something like FvwmTaskBar.orig, and put the taskbar with plugins
in its place.

Now run make distclean, configure and build as you normally would,
from the top level of the fvwm95 source tree.  Be sure to do the
distclean, since the changes I made to Makefile.in will only be seen
if the Makefiles are re-created.  Neglecting this will most likely
cause compile time errors about FVWM_ICONDIR, which I added to the
Makefile.

Check the Makefile created.  It is by default setup for my environment,
which is Solaris 2.5.  Dynamic linking is different on many platforms,
so uncomment the Linux region, and comment the Solaris region in the
Makefile if needed.


Bugs in FvwmTaskBar:

I also fixed a couple small existing bugs in the task bar.  The
checking for .fvwm95rc options was not correct for anything starting
with Auto, due to an incorrect length when checking for "AutoHide".
LoopOnEvents made the assumption that all the X Event structures had a
time field in the same place.  Since this is obviously wrong, I made a
change to fix this.

The list of buttons used in ButtonArray.{c,h} does not include the id
of the window.  It seems, iconized and sticky windows were in the
windows list and also fvwm messages caused them to be added twice.  I
tried to hack a quick fix, but it needs to be done like FvwmWinList
current code does.

Also, I ran gcc with -Wall, and this revealed many unused variables,
so I went through and cleaned all this up.

I made a simple fix to the bug reported to the fvwm95 mailing list
by Christian Worley <cworley@altatech.com>.  The problem was an
inconsistency between the module load fcn declarations and how it
was called.


My Changes to FvwmTaskBar:

I have made some changes FvwmTaskBar (and the plugins) to optionally
see new unread mail on the taskbar.  See the man page for FvwmTaskBar
for more details.  I modified the Tip window to be able to handle
multiple lines.  Then I used this to show entries from the users mail
spool file.  The location of this file is the same as for the mail fcn
the taskbar had before.  I also made a mod to allow an arbitrary
command to be run on the hour.  I use this to play sounds indicating
that another hour of my life has slipped away.  :^)

Note that I needed to change the interface for a GoodyModule to
include the loadable module's integer id in the init call.  This
allows me to decide if the AutoMailTip window is still open when the
mail file becomes empty, and the tip needs to be removed.  All
provided goody modules have been changed.

There is a small problem with the AutoMailTips as it stands now.  If
the screen is xlock'ed when the mail tip is displayed, it seems to
"fight" with xlock for control.  This shows my lack of knowledge in
programming X, but I think it has to do with responding to the unmap
call from xlock.  This is not fatal, and is acutally a nice way to see
if I have mail w/o unlocking the screen.  (Yeah, I know I am just
trying to justify it to myself)

There was also a problem with FvwmTaskBar needing a line in
~/.fvwm95rc to find the icon files (specifically for the start menu).
I changed the Makefile to pass the default FVWM_ICONDIR as it does for
fvwm.  (I also changed all the Makefiles to support installing not in
/usr/lib/...  since I don't have root access where I am -- these
changes are not in any diffs) Now icons do not have to be fully
qualified pathnames, and can just use the same icon directory as every
other part of fvwm.

08/12/1997

I received several customization requests, that I decided to implement.
The options are documented below.


Details and sample .fvwm95rc:

     *FvwmTaskBarMaxTipLines [num]
          This controls the maximum number of lines allowed in a
          multi-line tip window.  The first [num] are displayed,
          and if more than [num] lines are in the tip text, the
          last line will read "(more...)" to indicate it.  The
          default for this is 30.


     *FvwmTaskBarMailCheckModuleAutoMailTip<id> [type]
          This option controls the auto-display of new mail in  a
          multi-line  tip  window.   Three  possible  values  are
          allowed  for  the   optional   type   argument:   Mail-
          FileTouched,   MailFileBigger,   or  MailFileAnyChange.
          MailFileTouched means the  mail  spool  file  has  been
          modified  since the last access, MailFileBigger is when
          the mail spool file gets  larger  in  size,  and  Mail-
          FileAnyChange  is  when the mail spool file gets larger
          or  smaller.   These  conditions   control   when   the
          AutoMailTip  window is displayed.  The default is Mail-
          FileAnyChange.


     *FvwmTaskBarMailCheckModuleMailTipFormat.MAIL [l] [if] [wf] [is] [ws]
          This options allows specification of how to display the
          mail information in the tip.  [l] can be either 1 for
          a single line per mail message, or 2 for a double line
          format where the From: info appears on one line, and the
          Subject: appears on the next line.  [if] is the number of
          spaces to indent the From: info, and [wf] is the max width.
          [is] and [ws] are the indent and width of the Subject: info.
          The default is 1 0 20 2 30.


     *FvwmTaskBarMailCheckModuleMailTipNoSmartFrom
          If set, this flag shuts off the automatic name extraction
          for the From: field.  The format seen in email is largely
          formatted by convention, and this allows this process to
          be shut off when it does not work.

          The smart name extraction algorithm works as follows.  Step 1:
          all substrings delimited by <> and [] are removed, since
          they usually contain an email address.  If nothing is left,
          this step is reversed.  Step 2: if any string delimited by ""
          or () is found, it is used as the smart name.  Otherwise the
          result from Step 1 is used at the result.  For most email I
          have, this results in nicely formatted names.


     *FvwmTaskBarMailCheckModuleMailTipUnblankScreen<id>
          If set, the screen will be un-blanked when the mail tip
          is drawn.


     *FvwmTaskBarShowDateModuleHourlyCommand<id> command
          Executes the command every hour.
