file:   Qtk::QuickTk-0.88.readme

  QuickTk provides a quick and simple way to produce point-and-click
applications, using the perl-tk GUI toolkit.  It assumes a beginner's
level of familiarity with perl-tk, as documented in any of several
recent books (See, for instance, Nancy Walsh's "Learning Perl/Tk",
published by O'Reilly, 1999, ISBN: 1-56592-314-6).

  The QuickTk format for specifying a GUI (graphical user interface)
is simple.  A complete application can be defined in a short, one
or two page document (see the examples included with this module).
You need Perl, perl-tk, this module and, probably, the companion
module Text::TreeFile, in order to support the script you write.

  The perl-tk widget library (Tk, for short) provides "widgets"
(things you see on the screen, like buttons) and "events" (things
that can happen to a widget, like a click, right-click or double-click
of the mouse on a button).  You need to know only about the specific
widgets and events of Tk you wish to use, and enough Perl to say what
should happen when your user makes an event happen in one of your
widgets.

DOCUMENTATION

  There are man pages for Qtk::QuickTk(3pm) which introduces the
functions and use of the modele,  Qtk::QuickTk::scripts(3pm) which
provides detailed information about the format for writing GUI
specification scripts for QuickTk, Qtk::QuickTk::details(3pm) which
gives exhaustive specification of alternatives and features for use,
and Qtk::QuickTk::internals(3pm) which documents the code itself.
Another module: Text::TreeFile(3pm) is used by default and, thus,
its documentation is descriptive of the low-level format features
usually employed for this module.

AVAILABILITY

  Copyright (c) 2000 John Kirk. All rights reserved.
This program is free software; you can redistribute it and/or
modify it under the same terms as Perl itself.

  The latest version of this module should always be available
at any CPAN (http://www.cpan.org) mirror, or from the author:

INSTALLATION

  I usually install modules using the CPAN.pm module, invoked as:

       perl -MCPAN -e shell

It can be run by an ordinary user, or root (to install system-wide),
and asks a few configuration questions the first ime it's run.

  The *.tar.gz file, after being uncompressed and unarchived, expects
to be installed with the following commands:

       perl Makefile.PL
       make
       make test

  This creates and installs man pages, generated from *.pm and *.pod
files, among other things.

SYNOPSIS

  use Qtk::QuickTk;

  # for a QuickTk GUI spec document in file: scriptfile.qtk:
  my $app=Qtk::QuickTk->new('scriptfile.qtk');

  MainLoop;

or you can make the script file directly executable by giving it
the following as its first line:

  exec /usr/bin/perl -M'Qtk::QuickTk-app' -e app $0;exit

  See example scripts, provided with the module, to get the flavor
of what scripts look like.

CAVEAT

  QuickTk defines only a simpler format for writing the specification
for a GUI-based application which uses the perl-tk widget library.
Familiarity with, or reference to, that library is required to use
QuickTk.  The module, Text::TreeFile(3pm) is used, by default, for
interpreting the low-level file format in which GUI specifications
are written, so familiarity with, or reference to, that module may
be helpful in using QuickTk.

REQUIRES

  QuickTk uses modules:  Text::TreeFile(3pm) (optionally),
Tk(3pm), FileHandle(3pm), Carp(3pm), English(3pm), Exporter(3pm)
and Autoloader(3pm).

CONTENTS

  This distribution provides the following:

QuickTk.pm  -- the code for the module, which your program will
  access with a "use Qtk::QuickTk;" statement, typically.  Pod
  documentation is embedded in this file, from which the man page,
  Qtk::QuickTk(3pm) is generated.

scripts.pod  -- plain old documentation exhaustively describing
  the syntax functionality of the GUI specification format
  supported   by the QuickTk module, from which the man page,
  Qtk::QuickTk::scripts(3pm) is generated.

details.pod  -- plain old documentation exhausively specifying
  the options for use of the module, from which the man page,
  Qtk::QuickTk::details(3pm) is generated.

internals.pod  -- plain old documentation of the module code
  itself, from which the man page, Qtk::QuickTk::internals(3pm)
  is generated.

test.pl  -- a small program which contains hand-coded copies of
  data structures that would result from using the Text::TreeFile(3pm)
  to read the miniapp example file, which displays a menu bar, a task
  bar and a text window, requests the user to follow a brief procedure
  and reports results.
