Perl/Tk FAQ part 5 of 5 - Miscellany
************************************


______________________________________________________________________



18. How do I "clear the screen"?

What screen are you trying to clear?

If you are trying to clear a tty (e.g. xterm) screen then try either of the
following within your script:

    system "clear";
or
    print `clear`;

(where the choice between these two depends on the rest of the script: the
first is fast - but proceeds via fork and may not occur at exactly the time
that you want it to in the script).

David and Rachel Weintraub <[email protected]> recommend using
the old termcap.pl p4 library. You might also consider the perl 5
equivalents: Term.pm (especially the Term::Control module),
Curses.pm, Perlmenu.pm, PV.

Returning to X-windows and perl/Tk: if you are trying to eliminate a
TopLevel or a MainWindow then try:

    $main -> destroy;

If you would rather not destroy then try:

    $main->withdraw;    # remove

    $main->deiconify;   # put back

If $w is a sub-window (sub-widget) then

    $w->pack('forget'); # remove if packed (newer Tk-b9.01++)
    $w->packForget;     # remove if packed (older versions)
    $w->pack(...);      # put back

There are also ways to call low level C-ish versions:

    $w->UnmapWindow;

but that is for special purposes only....

If you are trying to erase an $item on a Canvas then try:

    delete($item);

(Thanks to the post by <[email protected]> which extended this
answer considerably.)

19. Are there any international font packages for perl/Tk?

In principle you may specify the -font configuration option on all your
Button, Entry, Label, Message, etc. widgets. In addition to the Unix
programs xfontsel and xlsfonts you may find xset useful for determining
and/or specifying fonts - especially international ones.

KOBAYASI Hiroaki <[email protected]> has converted the
Tcl/Tk "japanization" by <[email protected]> so that it may be used with
perl/Tk. It is presently available (the current README file is in Japanese)
from the following ftp site:

    ftp://ftp.sowa.is.uec.ac.jp/pub/Lang/perl5/Tk/

From the author's own description:

Currently, the "japanization patch for perl/Tk" enables:

  [1] To show kanji & ASCII (by choosen kanji-font) in every widget.
  [2] To edit kanji (double width of ASCII) correctly in Text & Entry.
  [3] To support of Kanji Input method. (tkKinput.c)
  [4] Automatic kanji-code-detection & conversion with 'insert/get'.
      Supports: "JIS(Japanese Industrial Standard)", "MS-KANJI", "EUC".

& the patch lacks:

  [5] by manual Kanji-code conversion. (JIS <=> MS-KANJI <=> EUC)
  [6] 'Good' interface to specify kanji-code used in internal. (tkWStr.c)
  [7] Documentation in English about [1-6].
      # but, since interface-change is suspected in near future,
      # documenting them is ...

I thought that[5-7] was not enough for world-people, but already worth
for natives. So I announced it on "fj.lang.perl".

______________________________________________________________________



20. Are there any other ways to create X interfaces from perl?

Yes. A short list would have to mention:

For perl 4:
   WAFE, STDWIN
For perl 5:
   Sx (uses Athena & Xlib), Motif (uses Motif & Xt), Fresco (post
   X11R6.1). This perl extension was originally written by Dominic
   Giampaolo, but was re-written for Sx by Frederic Chauveau. The
   code is available from CPAN in the
   authors/Frederic_Chauveau/ directory.

There is also Malcolm Beattie's Tkperl (which is largely incompatible with
perl/Tk).

Further information on X interfaces to Perl is provided in the perl FAQ.

There is also an OpenGL Perl Module (of particular interest to SGI, Sun
mesaGL, and AIX developer folks). If you would like to see the OpenGL
network X demonstration go to:

    http://www.arc.ab.ca/vr/opengl/examples/

(to run that demo one needs only a forms capable web browser and a local
X-server, hence running Lynx on Windows 95 with eXodus is perfectly
OK.) If you would like to see the OpenGL netscape plugin go to:

    http://www.arc.ab.ca/vr/opengl/plugin.html

For perl generation of images see the question in this FAQ on graphics
modules.

______________________________________________________________________



21. Where can I get more information on graphics [modules|scripts]?

To generate server side push animation in perl please see the perl cgi FAQ.
To generate GIF89a loops from a collection of stills visit the Gifloop page.

There are several graphics modules in perl already available - with several
more still under development. Among them:

GD.pm
   The GD.pm perl module is a perl interface to the C code of a
   similar name and was written by Lincoln Stein. It allows for the
   generation of GIF (Graphics Inline Format) images from within a
   perl script. The module itself is available from any CPAN ftp site,
   and Lincoln maintains an informational web page at:

    http://www-genome.wi.mit.edu/ftp/pub/software/WWW/GD.html

gd/GIF.pm
   The gd/GIF.pm module is similar to GD.pm (generates GIFs
   using gd.c) and was written by Roberto Cecchini who maintains a
   web page for his module at:

    http://www.fi.infn.it/pub/perl/GIF/

JPEG.pm
   The JPEG.pm module was written by Nick Ing-Simmons
   expressly for use with the Tk family of modules. It is distributed on
   CPAN in the authors/id/NI-S/ directories as a
   Tk-JPEG-*.tar.gz file.

PGPERL
   If you will be interfacing to the PGPLOT FORTRAN language
   routines you might consider Karl Glazebrook's PGPERL which
   has an interactive web demo as well a a web home page at:

    http://www.aao.gov.au/local/www/kgb/pgperl.html

A pgperl/tk script might look like this:

    #!/usr/bin/perl
    use PGPLOT;
    use Tk;
    open(IMG,"test.img");       # Read 128x128 image from binary file
    read(IMG, $img, 4*128*128); # data - list of 4 byte float [C type]
    close(IMG);                 # stored as perl string.
    pgbegin(0,'test.gif/gif',1,1);
    pggray($img,128,128,1,128,1,128,1,0,*tr); # pg-Plot it
    my $main = new MainWindow;
    $main ->Label(-text => 'Main')->pack;
    $main -> Photo('IMG', -file => "test.gif");
    my $l = $main->Label('-image' => 'IMG')->pack;
    $main->Button(-text => 'close',
                  -command => sub{destroy $main}
                  )->pack(-side => 'left');
    $main->Button(-text => 'exit',
                  -command => [sub{exit}]
                  )->pack(-side => 'right');
    MainLoop;                    # pg-tk plot it

A tip for the tuned in: keep an eye on Karl :)

22. Are there any major applications written in perl/Tk?

Yes. In fact, there are some interesting perl/Tk applications already
available from:

Your very own perl/Tk distibution:
----------------------------------

The following programs may be found in your own Tk#/ directory (you
already have these if you have the Tk extension to perl)*:


program        description
pfm            perl file manager - cute iconic front to emacs
ptknews        a GUI perl newsreader (Tk-b9.01) - a work in progress.
tkpsh          perl/Tk equivalent of wish.
toyedit        a Text widget editor.

The following programs may be found either in your demos directory
(consult the README file there for fuller descriptions) or in your perl/bin
install directory:


program        description
browse         Simple file browser front end for emacs.
color_editor   Front end to Tk::ColorEditor
               allows RGB, CMY, and HSV color cube manipulation
               (based on tcolor.tcl).
ixset          GUI front end to xset - for terminal settings.
pgs            Perl front end to Ghostscript (viewing PostScript(c) files).
rmt            perl/Tk
               "development shell/remote control application"
               You can launch or talk to other perl/Tk apps with rmt.
rolodex        Like the Tcl/Tk app of the same name.
               Requires editing for personal use.
timer          Stopwatch-like seconds timer.
tkpod          The perl gui pod viewer (like xman).
tkweb          The perl gui web browser.

*Peter Prymmer recently posted a means by which one can integrate any
or all of these GUI applications into one's own X-window environment.
Here for terse illustration is the basic idea behind using an X11R6.1
.mwmrc.m4 resource file for making a Menu (make sure the applications
are in your PATH or specify a full path to each one as needed):

Menu Perl
{
    "Perl"          f.title
    "editor"        f.exec "toy_edit &"
    "tkemacs"       f.exec "browse &"
    "manual"        f.exec "tkpod perl.pod &"
    "the web"       f.exec "tkweb http://www.perl.com/perl/ &"
    "news"          f.exec "ptknews comp.lang.perl.tk &"
    "pgs"           f.exec "pgs &"
    "stop watch"    f.exec "timer &"
}

# We bind it so that left mouse button when pressed while
# over the root or background pops up with this Perl menu:
Buttons DefaultButtonBindings
{
    <Btn1Down>      root       f.menu  Commands
    # etc.
}
Buttons ExplicitButtonBindings
{
    <Btn1Down>      root       f.menu  Commands
    # etc.
}

Other perl/Tk application distributors:
---------------------------------------

ptkb.pl
   an xbiff like mailbox watcher. Available from
   ftp://ftp.wpi.edu/perl5/pTk-Modules/ptkb.pl
bioTkperl
   Was announced by Gregg Helt <[email protected]>
   recently. See the home page at:
   http://www.cbil.upenn.edu/~dsearls/bioTk.html. Source at:
   ftp://fruitfly.berkeley.edu/pub/bioTk/bioTkperl0.8.tar.gz
EVA
   KOBAYASI Hiroaki's EVA is a sophisticated wish like perl/Tk
   "shell". It is available from:
   ftp://ftp.sowa.is.uec.ac.jp/pub/Lang/perl5/Tk/eva-*.tar.gz
plop
   Stephen Lidie's very useful arbitrary function Plot Program, was
   featured in the premier issue of The Perl Journal and is available
   on the web at:
   http://orwant.www.media.mit.edu/tpj/programs/Vol_1_Issue_1_Tk/plop
modo
   Yet another Lidie creation. This one hails from Issue 2 of The Perl
   Journal
Workspace
   Is an integrated front end to the fvwm window manager that makes
   use of Perl/Tk. See the web page at http://www.mirai.com/wks/ for
   more information.
www
   The original 8 line wonder by Jon Orwant. Pick it up (and modify
   it) from:
   http://sun20.ccd.bnl.gov/~ptk/archive/ptk.1995.08/0411.html.
   (Please note: www is for amusement, the more serious perl/Tk
   browser - tkweb - is distributed with perl/Tk and it is "only" 60
   lines long!.)
ptkclock & ptkmines
   From the generous software archive of Jason Smith at RPI.
XCricket.pl
   This application was written by Nem Schlecht.

Be sure to also check the newsgroups comp.lang.perl.tk,
comp.lang.perl.announce, comp.lang.perl.misc, and
comp.lang.perl.modules, as well as the mailing list archive for more
Perl/Tk program and package announcements.

23. What is the history of pTk and perl/Tk?

This list is only slowly coming together. Please forgive any absences.

 o tkperl5a5 is announced Thu, 20 Oct 1994 14:44:23 +0000 (BST)

NOTE
This project is unrelated to the one which is adding usersubs to
perl4 to get access to Tk via Tcl. Often, postings on comp.lang.perl
just say "tkperl" without saying which one is meant. They are two
totally different kettles of fish.

______________________________________________________________________



24. What can we expect the future to hold?

Tk400.200 was released on 6 September 1996. Here are some highlights
from the Changes file:

Changes in Tk400.200

 o Fixed typos in tkPort.h, accept perl5.002 and later, including
   conditional compile for 5.003_04
 o Fixed bug with menu traversal and entering upper-case caused by
   Tk-b12's attempt to enable Solaris's keypad.
 o Tolerate 'extreme POSIX-ness' for 'irix'.
 o Added some more converted Tix stuff to Contrib
   - Tix stuff will probably become a separate CPAN module.
 o Messy hack to cause pod documentation to get added to HTML
   version - doc directory now processes pre-installed pod2man
   output!
 o Made default for -scrollbars option to be non-optional can now
   have string matching /([or]?[ns])?([or]?[ew])?/ that is 'n' or 's',
   prefixed by optional 'o' or 'r' 'e' or 'w', prefixed by optional 'o' or
   'r' The 'r' (for required) is ignored as it is new default (as in
   pre-Tk-b11) 'o' causes that scrollbar to only be visible if needed,
   as in Tk-b11..Tk-b12
 o Some new pods courtesy of Achim Bohnet
   <[email protected]>
 o Convert '.o' to $(OBJ_EXT) when writing Makefiles - for OS/2.

With the production release of Tk400.200 (corresponding to Tk 4.0p3)
work will begin in earnest on the widely cross-platform Tk4.1. Initial
pre-releases have been compiled to work with X and PM on OS/2 hence
the future of this code looks quite bright :-).

~~~~~~~~~~~~~~~~~

With e-mail you might try one of the (experimental & not necessarily
reliable) http-to-mail services such as either of the following:

When last tested the service at <[email protected]> reported that the
single ptkFAQ.txt file was too large to send. Hence, you must send
several separate e-mail requests to <[email protected]>
A Subject: line is not required but do include the following one line
message body in your first e-mail:

    GO http://w4.lns.cornell.edu/~pvhp/ptk/ptkFAQ0.txt

Then send several more (separate) requests as follows:

    GO http://w4.lns.cornell.edu/~pvhp/ptk/ptkFAQ1.txt

please note: In days gone by this service would take several hours to send
back both a plaintext and a uuencoded version of the stated file - both
within a single mail message. The service did mention receiving more than
17,000 requests in October 1995 alone and it is not known whether they
will continue.


Send e-mail to <[email protected]>
with a one line message body (Subject: line not required) such as:

    SEND http://w4.lns.cornell.edu/~pvhp/ptk/ptkFAQ.txt

please note: this last method bounced backed a "permanently out of
service" message when last attempted. The home page at
http://www.w3.org/hypertext/WWW/Agora/ mentions "temporarily out of
service", caveat netsurfer; the page at
http://www.w3.org/pub/WWW/MailRobot/send.html does not mention
being out of service.
System administrator and webmasters are encouraged to visit any of the
following pages:

    http://www.w3.org/pub/WWW/MailRobot/Overview.html
    http://www.w3.org/pub/WWW/MailRobot/send.html
    http://www.w3.org/hypertext/WWW/Mailing/Form.html
    http://www.w3.org/hypertext/WWW/Agora/

and decide if they wish to set up a webmail gateway of their own. The
agora.pl script is written in perl and makes use of the www line mode
browser. It could presumably be re-written to use url-get.pl or any
other fine code such as the latest, greatest perl5 module for URL fetching
:-)

public browsers
~~~~~~~~~~~~~~~

telnet www.njit.edu log in as www, use Lynx. (Thanks to Tom
Phoenix <[email protected]> for that :-)

gopher
~~~~~~

For Perl/Tk only you can try:

    gopher-client 128.84.219.153

or in URL form:

    gopher://128.84.219.153/1

For a gopher hole with extensive Perl information/source-code/etc. try
Bill Middleton's extensive metronet site:

    gopher-client gopher.metronet.com
or
    gopher-client 192.245.137.6

in URL form that would be:

    gopher://gopher.metronet.com/1
