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-masked]> 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-masked]> 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-masked]> has converted the
 Tcl/Tk "japanization" by <[email-masked]> 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 and
 AIX developers but apparently also useful to folks who have the MesaGL
 library as well. 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 at 
 
    http://www.homecom.com/gifanim.html
 
 For other animation from perl see the OpenGL module listed below (it
 does 3D VRML animation). 
 
 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. 
 
 Open/Mesa-GL Perl Module
    This module can use the OpenGL lib on computers that have it
    (available for SGI, AIX, Linux), or with the MesaGL package
    (which allegedly runs a little slower but does not require the X
    accelerator hardware that OpenGL does). This package supports
    relatively easy graphics programming, 3D shading, etc. Very cool
    stuff! The URL for the OpenGL perl module is: 
 
     http://www.arc.ab.ca/vr/opengl/
 
 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
 
 perlDL
    perlDL or PDL is the Perl Data Language for fast manipulation
    of large arrays - such as those that often occur in image
    processing/analysis/creation (or scientific data sets). PDL is also
    by Karl Glazebrook. This is a very hot module full of programmer
    convenience features such as overloaded operators etc. There is a
    mailing list and a home page for this module: 
 
     http://www.aao.gov.au/local/www/kgb/perldl/
     [email-masked]
     http://www.rosat.mpe-garching.mpg.de/mailing-lists/perldl/
 
 Another tip: it is quite useful to have the PBMPlus/NetPBM set of
 graphics file interconversion programs if you will be dealing with many 
 graphics file formats. There is a Sunsite web server with many graphics
 utilities including netpbm at: 
 
     http://sunsite.unc.edu/pub/Linux/apps/graphics/convert/INDEX.short.html
 
 (Note there are linux binaries as well as source code kits there - also at
 sunsite mirrors.) You might also be interested in some of the graphics
 file format specifications. 
 
 Other programming tools/utilities are of help with graphics. The X11
 release contains many such tools. There is also The GIMP. Consider also
 the ImageMagick program.

 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 - a work in progress.
 tkpsh          perl/Tk equivalent of the Tcl/Tk wish shell.
 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.
 }

    Yet another Lidie creation. This one hails from Issue 2 of The
    Perl Journal 
 neko (et al.)
    In the third issue of The Perl Journal Stephen Lidie makes
    creative use of approaches to event timing from perl/Tk. neko is
    one axample.

 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.

    what will be known as "nTk" eventually. 
  o Mon, 12 Dec 94 08:56:36 GMT, Nick Ing-Simmons reports: 
 
 I have a re-port of ext/Tk nearly ready for alpha.

 from Tk3.6.  There is no Tcl library at all. 
 
 Would anyone like to assist me in testing it?

 ______________________________________________________________________

 
 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-masked]> 
  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 :-).

 ftp - usenet archives
 .....................
 
 This Perl/Tk FAQ is cross posted to several *.answers newsgroups
 hence, this FAQ is being carried by the big usenet anonymous ftp servers
 such as: 
 
     ftp://rtfm.mit.edu/pub/usenet/
     ftp://rtfm.mit.edu/pub/usenet/perl-faq/ptk-faq/
     ftp://rtfm.mit.edu/pub/usenet/comp.lang.perl.tk
     ftp://rtfm.mit.edu/pub/usenet-by-hierarchy/comp/lang/perl/tk
 
     ftp://ftp.uu.net/usenet/news.answers/perl-faq/ptk-faq
     etc.
 
 e-mail services:
 ~~~~~~~~~~~~~~~~
 
 Send e-mail (content of message unimportant) to 
 <[email-masked]> and you will receive the text version of this
 FAQ. (Many thanks to Alan L. Stange at Brookhaven for setting this
 up!) 
 
 Those without FTP access can get the plaintext version via e-mail from
 the rtfm archive. For help send e-mail to <[email-masked]>
 with a message of:
 
     send usenet/news.answers/finding-sources
 
 The mail server at rtfm may be able to e-mail a plaintext version of this
 faq. Send e-mail to <[email-masked]> containing: 
 
     send /pub/usenet/news.answers/perl-faq/ptk-faq/part0
 
 Then send several more (separate) requests, such as: 
 
     send /pub/usenet/news.answers/perl-faq/ptk-faq/part1
     send /pub/usenet/news.answers/perl-faq/ptk-faq/part2
     send /pub/usenet/news.answers/perl-faq/ptk-faq/part3
     send /pub/usenet/news.answers/perl-faq/ptk-faq/part4
     send /pub/usenet/news.answers/perl-faq/ptk-faq/part5
 
 The [email-masked] mailing list is also devoted to porting,
 development, and support issues. The URL's to this FAQ will
 occasionally be posted there, but not the full text (it is simply too big -
 sorry).
 
 Webmail Gateways:
 ~~~~~~~~~~~~~~~~~
 
 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-masked]> reported that
 the single ptkFAQ.txt file was too large to send. Hence, you must send
 several separate e-mail requests to <[email-masked]>
 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
     GO http://w4.lns.cornell.edu/~pvhp/ptk/ptkFAQ2.txt
     GO http://w4.lns.cornell.edu/~pvhp/ptk/ptkFAQ3.txt
     GO http://w4.lns.cornell.edu/~pvhp/ptk/ptkFAQ4.txt
     GO http://w4.lns.cornell.edu/~pvhp/ptk/ptkFAQ5.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-masked]>
 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-masked]> for that :-) 
 
 gopher
 ~~~~~~
 
 The former Perl/Tk gopher site has been taken off the internet. 
 
 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
