54 Introduction
55------------------------------------------------------------------------------
56 [incr Widgets] is an object-oriented mega-widget set which extends
57 Tcl/Tk and is based on [incr Tcl] and [incr Tk]. This set of mega-widgets
58 delivers many new, general purpose widgets like option menus, comboboxes,
59 selection boxes, and various dialogs whose couterparts are found in Motif
60 and Windows. Since [incr Widgets] is based on the [incr Tk] extension, the
61 Tk framework of configuration options, widget commands, and default bindings
62 is maintained. In other words, each [incr Widgets] mega-widget seamlessly
63 blends with the standard Tk widgets. They look, act and feel like Tk
64 widgets. In addition, all [incr Widgets] mega-widgets are object oriented and
65 may themselves be extended, using either inheritance or composition.
66
67 [incr Widgets] offers a strong object-oriented foundation which addresses
68 the need for a flexible and extensible mega-widget set. Its usage replaces
69 common widget combinations with higher level abstractions, simplifying code,
70 reducing errors, increasing readability, adding productivity, and promoting
71 a singular look-and-feel. The ability to extend [incr Widgets] enables
72 developers to create new mega-widgets based on previous work.
73
74 In short, [incr Widgets] is a library of reusable mega-widgets that can
75 be easily extended using composition or inheritance, allowing quicker
76 development of large scale applications. Usage drastically reduces
77 development time. New dialogs can be created in hours. Whole applications
78 in a few days. Reuse becomes a reality. Many projects are benefitting frm
79 the intergration of this mega-widget set into their development strategy.
80 [incr Widgets] is an [incr Tcl] and [incr Tk] success story. Good products
81 come from good foundations.

84 Distribution
85------------------------------------------------------------------------------
86 The [incr Widgets] distribution may be downloaded at SourceForge:
87 www.sourceforge.net/projects/incrtcl. The current distribution is
88 version 4.0.1.
89
90
91 Web site
92------------------------------------------------------------------------------
93 For the most current news regarding [incr Widgets] please consult the web
94 site - http://incrtcl.sourceforge.net/iwidgets. Many thanks to Brett Schwarz
95 who has done an incredible job overhauling this site. Take a look!

97
98 Getting started
99------------------------------------------------------------------------------
100 The "doc" directory contains man pages and a technical paper. The man
101 pages are installed under the man directory off your --prefix, and as of
102 version 4.0.1 are prepended with the text "iwidgets_" to easily differentiate
103 [incr Widgets] man pages from those of other extensions.
104
105 doc/iwidgets.ps ... Updated paper presented at Tcl Workshop 95.
106
107 doc/*.n ........... Man pages
108
109 The "demos" directory contains demo scripts for each mega-widget as
110 well as html versions of all the [incr Widgets] man pages. The
111 demos are also installed under the lib directory off your --prefix.
112
113 demos/catalog ..... Comprehensive demo package which illustrates
114 [incr Widgets] usage additionally displaying the
115 source.
116
117 demos/html ..... HTML version of the [incr Widgets] man pages.
118
119 The "tests" directory contains a set of test scripts for [incr Widgets].
120 They also make for a great demo of the flexiblity of the mega-widgets.
121

123 Installation
124------------------------------------------------------------------------------
125 NOTE: Having the itcl distribution is a prerequsite to using iwidgets.
126 Thus, if you don't have itcl you need to visit Source Forge to download
127 and install it first. Once you have downloaded and installed [incr Tcl]
128 and [incr Tk], you can proceed with [incr Widgets] installation as follows:
129
130 1) Copy the iwidgets4.0.1.tar.gz file to your toplevel [incr Tcl]
131 directory. For example, if you have the itcl3.2.1 distribution in
132 a directory named /usr/local/tcl/itcl3.2.1, then you should copy
133 the iwidgets file to this directory.
134
135 Note, if you don't copy the iwidgets archive to this directory,
136 then you will need to specify the --with-itcl flag when you run
137 the configure script.
138
139 2) Untar/unzip the archive:
140
141 gunzip -c iwidgets4.0.1.tar.gz |tar xvf -
142
143 3) Run the configuration script:
144
145 cd iwidgets4.0.0
146 ./configure
147
148 By default, the configuration script will set things up to be
149 installed in "/usr/local". You can change this by specifying a
150 different "prefix" in the "configure" command. You'll want to
151 use the same value you used for the prefix in the configuration
152 of your [incr Tcl/Tk] distribution.
153
154 ./configure --prefix=/your/install/path
155
156 The "configure" script generates a Makefile from the Makefile.in
157 template.
158
159 Also, as mentioned eariler, you may need to tell the [incr Widgets]
160 where the [incr Tcl] source is located. For example, if your toplevel
161 [incr Tcl] directory is located in /opt/tools/tcl/itcl3.2.1 and you
162 are building the [incr Widgets] in a directory other than this, then
163 you will need to use the following:
164
165 ./configure --prefix=/your/install/path \
166 --with-itcl=/opt/tools/tcl/itcl3.2.1
167
168 4) Run the test suite:
169
170 make test
171
172 7) Install the [incr Widgets] man pages, demos, and script files.
173
174 make install
175
