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.
|
| 82 |
|
|
|
| 83 |
|
|
|
| 84 |
|
|
Distribution
|
| 85 |
|
|
------------------------------------------------------------------------------
|
| 86 |
|
|
The [incr Widgets] distribution is included with [incr Tcl] version 2.0
|
| 87 |
|
|
and greater. It is available via ftp at ftp.neosoft.com/tcl. Consult the
|
| 88 |
|
|
included release documentation for installation notes. For the latest
|
| 89 |
|
|
in distribution information, this web site should be consulted.
|
| 90 |
|
|
|
| 91 |
|
|
The [incr Tcl] distribution will always include the most current release
|
| 92 |
|
|
of [incr Widgets] which was possible at the time of its release. It is
|
| 93 |
|
|
anticipated that [incr Widgets] will change more rapidly than [incr Tcl].
|
| 94 |
|
|
This being the case, in between [incr Tcl] releases, the latest version
|
| 95 |
|
|
of [incr Widgets] is also separately available via ftp at the same
|
| 96 |
|
|
location list above as well as the web site.
|
| 97 |
|
|
|
| 98 |
|
|
The version number of [incr Widgets] tracks the release of [incr Tcl]
|
| 99 |
|
|
for which it is compatible. The version numbering system for [incr Widgets]
|
| 100 |
|
|
includes an extra number. For example version 2.1.1 of [incr Widgets] is
|
| 101 |
|
|
compatible with [incr Tcl] 2.1. As the minor number of [incr Tcl] increases
|
| 102 |
|
|
the second digit of the [incr Widgets] version varies. This makes for
|
| 103 |
|
|
easy release identification.

------------------------------------------------------------------------------
|
| 117 |
|
|
The "doc" directory contains man pages and a technical paper. The man
|
| 118 |
|
|
pages are installed under the man directory off your --prefix. In
|
| 119 |
|
|
addition, the makefile includes an install-html target for creating
|
| 120 |
|
|
a HTML version of the man pages. They are placed under your prefixed
|
| 121 |
|
|
doc directory.
|
| 122 |
|
|
|
| 123 |
|
|
doc/iwidgets.ps ... Updated paper presented at Tcl Workshop 95.
|
| 124 |

|
|
doc/*.n ........... Man pages
|
| 126 |
|
|
|
| 127 |
|
|
The "demos" directory contains demo scripts for each mega-widget. The
|
| 128 |
|
|
demos are also installed under the lib directory off your --prefix.
|
| 129 |
|

Installation
|
| 141 |
|
|
------------------------------------------------------------------------------
|
| 142 |
|
|
[incr Tcl] with [incr Widgets]
|
| 143 |
|
|
|
| 144 |
|
|
As previously stated, the latest version of itcl contains the latest
|
| 145 |
|
|
version of iwidgets. Having the itcl distribution is a prerequsite
|
| 146 |
|
|
to using iwidgets. Thus, if you don't have itcl follow the these steps
|
| 147 |
|
|
to acquire itcl and iwidgets.
|
| 148 |
|
|
|
| 149 |
|
|
1) Read the distribution section notes above.
|
| 150 |
|
|
|
| 151 |
|
|
2) Obtain the [incr Tcl] 3.x distribution from the archive site like this:
|
| 152 |
|
|
|
| 153 |
|
|
ftp ftp.neosoft.com
|
| 154 |
|
|
cd /pub/tcl/sorted/devel/
|
| 155 |
|
|
binary
|
| 156 |
|
|
get itcl3.0.tar.gz
|
| 157 |
|
|
get itcl3.0.README
|
| 158 |
|
|
quit
|
| 159 |
|
|
|
| 160 |
|
|
3) Follow the directions in the itcl README file.
|
| 161 |
|
|
|
| 162 |
|
|
If you've already got itcl and have found a newer version of iwidgets
|
| 163 |
|
|
at neosoft, then follow the following steps.
|
| 164 |
|
|
|
| 165 |
|
|
1) Read the distribtion scetion notes above.
|
| 166 |
|
|
|
| 167 |
|
|
2) Obtain the [incr Widgets] 3.x.y distribution from the archive site
|
| 168 |
|
|
like this:
|
| 169 |
|
|
|
| 170 |
|
|
ftp ftp.neosoft.com
|
| 171 |
|
|
cd /pub/tcl/sorted/devel/
|
| 172 |
|
|
binary
|
| 173 |
|
|
get iwidgets3.0.1.tar.gz
|
| 174 |
|
|
quit
|
| 175 |
|
|
|
| 176 |
|
|
3) cd to your compatable itcl source directory. For example:
|
| 177 |
|
|
|
| 178 |
|
|
cd /usr/local/src/itcl3.0
|
| 179 |
|
|
|
| 180 |
|
|
4) Uncompress and untar the iwidgets distribution:
|
| 181 |
|
|
|
| 182 |
|
|
gunzip iwidgets3.0.1.tar.gz
|
| 183 |
|
|
tar xvf iwidgets3.0.1.tar
|
| 184 |
|
|
|
| 185 |
|
|
5) Run the configuration script:
|
| 186 |
|
|
|
| 187 |
|
|
cd iwidgets3.0.1
|
| 188 |
|
|
./configure
|
| 189 |
|
|
|
| 190 |
|
|
or, for systems that don't recognize "#!" in shell scripts:
|
| 191 |
|
|
|
| 192 |
|
|
cd itcl3.0
|
| 193 |
|
|
/bin/sh ./configure
|
| 194 |
|
|
|
| 195 |
|
|
By default, the configuration script will set things up
|
| 196 |
|
|
to be installed in "/usr/local". You can change this
|
| 197 |
|
|
by specifying a different "prefix" in the "configure" command.
|
| 198 |
|
|
You'll want to use the same value you used for the prefix in
|
| 199 |
|
|
the configuration of your itcl3.0 distribution.
|
| 200 |
|
|
|
| 201 |
|
|
./configure --prefix=/your/install/path
|
| 202 |
|
|
|
| 203 |
|
|
You can also add options for a particular "cc" compiler and
|
| 204 |
|
|
compiler flags:
|
| 205 |
|
|
|
| 206 |
|
|
./configure --with-cc=gcc --with-cflags=-g
|
| 207 |
|
|
|
| 208 |
|
|
The "configure" script generates new Makefiles from their
|
| 209 |
|
|
respective templates (Makefile.in).
|
| 210 |
|
|
|
| 211 |
|
|
6) Build the iwidgets library:
|
| 212 |
|
|
|
| 213 |
|
|
make all
|
| 214 |
|
|
|
| 215 |
|
|
7) Install the iwidgets library, man pages and script files.
|
| 216 |
|
|
|
| 217 |
|
|
make install
|
| 218 |
|
|
|
| 219 |
|
|
8) Optionally, you can install the html'ed version of the iwidgets
|
| 220 |
|
|
man pages:
|
| 221 |
|
|
|
| 222 |
|
|
make install-html
|
| 223 |
|
|
|
| 224 |
|
|
|
| 225 |

I feel that [incr Widgets] is a good start in the direction of establishing
|
| 228 |
|
|
a strong set of object-oriented mega-widgets, but I swear that everytime I
|
| 229 |
|
|
go back and look at the source I see an even better more simplier way
|
| 230 |
|
|
something could have been accomplished. Should anybody within the Tcl/Tk
|
| 231 |
|
|
community come upon an even better way, a great enhancement, or an awesome
|
| 232 |
|
|
new mega-widget altogether, please don't hesitate to send it to the author
|
| 233 |
|
|
listed in the header or myself, mulferts@spd.dsccc.com, as moderator. I or
|
| 234 |
|
|
any of the development team members are always available via email for a
|
| 235 |
|
|
technical interchange of ideas.
|
| 236 |
|
|
|
| 237 |
|
|
[incr Widgets] is a continuing effort. We have many new mega-widgets
|
| 238 |
|
|
currently under development and are actively looking for volunteers willing
|
| 239 |
|
|
to contribute their own [incr Tk] based mega-widgets for inclusion into
|
| 240 |
|
|
the [incr Widgets] set. The distribution is moderated. Contributed
|
| 241 |
|
|
mega-widgets should be of good quality and complete with documentation,
|
| 242 |
|
|
tests, and demonstrations. Please follow the coding style found in the
|
| 243 |
|
|
distribution source. This includes man page and test script formats as well.
|
| 244 |
|
|
The languages and extensions on which [incr Widgets] is based are of high
|
| 245 |
|
|
standards. [incr Widgets] strives to attain this same level. Be fore
|
| 246 |
|
|
warned, the moderator is a facist.
