O'Reilly Volume 4, Doug Young's Xt book, the Asente/Swick book, and Jerry
Smith's "Object-oriented Programming with the X Window System Toolkits" all
include details on writing widgets and include several useful widgets;
sources are typically on ftp.x.org, ftp.ora.com, or ftp.uu.net. Doug Young's
book, in particular, contains a version of a tree-like layout object (root
and multiple leaves that collapse and expand). In general, widgets accumulate
in ftp://ftp.x.org/contrib/widgets/ Unsorted older code is in
ftp://ftp.x.org/R5contrib/ .  See also http://www.wri.com/~cwikla/widget/ for
a index of widget listings.

The Free Widget Foundation (FWF) library coordinated by Bert Bos
(bert@let.rug.nl) is now [10/94] available on ftp.let.rug.nl (129.125.8.20)
in pub/FWF/fwf.tar.Z. The set of widgets there is intended to form the basis
for future contributions; it contains approximately 40 widgets of varying
degrees of complexity.  Several of the widgets are simple, primitive widgets,
including buttons and labels; others are sophisticated, high-level widgets
supporting advanced user interface tasks such as hierarchical file selection,
statistical data presentation, and image editing.  To be added to the
discussion list, send to listserv@let.rug.nl a message saying "subscribe
<listname> <your-full-name>" where <listname> is one of
free-widgets-announce, free-widgets-development, or free-widgets-bugs. The
current [4/96] version is 4.0.

ListTree, by Robert W. McMullen (rwmcm@orion.ae.utexas.edu), is available
from ftp://ftp.x.org/contrib/widgets/ListTree-2.0.tar.gz [4/96].  The
ListTree widget, designed for use in file manager programs but widely
applicable, displays lists of text strings (with an optional pixmap) in a
hierarchical directory list format.  This widget does not use widgets for
each item displayed in the tree; instead, it is a list of text strings that
contain pointers to parents and children in the tree, reducing memory usage
and simplifying use.  The ListTree widget is compatible with Athena and
Motif.  Information:  http://www.ae.utexas.edu/~rwmcm/ListTree.html .

A widget that displays nodes in a tree outline form is on
ftp://ftp.x.org/contrib/widgets/motif as outline.tar.gz. [4/96]

An *alpha* version of a tree widget with collapse/expand children capability
is at http://www.ii.uib.no/~torgeir/work/outline.html .  The tree widget is
really two widgets, one of which is a manager which draws the background
outlines; the other is a "handle" widget which enables collapsing and
expanding by unmanaging and managing its outline widget.  Info: Torgeir Veimo
(torgeir@ii.uib.no) [1/95]

The ProgressMeter widget for Motif 1.2.x is at
ftp.gsf.de://pub/mperzl/ProgressMeter-0.1.tar.gz . It offers a thermometer
look or the MS Windows "brick" meter style.

A single-line text-entry widget by Robert W. McMullen
(rwmcm@mail.ae.utexas.edu) is available from
ftp://ftp.x.org/contrib/widgets/TextField-1.0.tar.gz ; information on it is
available from http://www.ae.utexas.edu/~rwmcm/TextField.html .  The
TextField Widget is a low resource single line text input widget designed to
mimic the functionality of the Motif XmTextField widget.  To benefit freeware
programmers who may now be using the Athena widget set, this widget was also
designed to be as compatible as possible with the Athena Text widget (in
single line mode). It shares many of the resources with the Athena Text
widget, and few code modifications are necessary to change to the TextField.

A release of the Xaw widgets with a 3D visual appearance by Kaleb Keithley
(now kaleb@x.org) is available on ftp://ftp.x.org/contrib/widgets/Xaw3d/
(updated 4/95 to R6; updated 8/95 to release 1.2).  The library, which is
binary-compatible with Xaw, implements a 3D subclass which handles the extra
drawing.  In general, you may relink almost any Athena Widget based
application with the Three-D Athena Widget set and obtain a three dimensional
appearance on some of the widgets. On systems with shared libraries, you may
be able to replace your shared libXaw with libXaw3d and obtain the three
dimensional appearance without even relinking.

The NCSA Mosaic distribution includes an HTML widget which take an ASCII
string in Hyper Text Markup Language and formats it for display in an X
window.  Information: http://www.ncsa.uiuc.edu/SDG/Docs/htmlwidget.html .

A Motif XmpSpinBox widget by Charles S. Kerr (cskerr@delenn.jccbi.gov) is
available at http://www.wildstar.com/~cskerr/spinbox (sources are also on
ftp://ftp.x.org/contrib/widgets/motif/spinbox/ ).  A spinbox consists of two
arrowbuttons and one textfield which are arranged in a number of different
layouts. The textfield shows data; the arrowbuttons can be used to scroll
through the different values in a number of built-in formats: numbers, a
24-Hour clock, dollars, and text strings.  Version 1.3 is current [4/96].

An object like the Windows "combo box" is part of the Xm++ class library.

Interleaf has made available several widgets which it has contributed to the
COSE group producing the CDE (Common Desktop Environment); all the code
carries Copyright notices granting unlimited right to copy, modify, and

to Windows users:  spin buttons, drop-down list boxes, and combo boxes.
Sources are available in ftp://ftp.cs.umb.edu/pub/interleaf/CDE [4/96].

(normal, armed or insensitive).  The library is available at
ftp://ftp.informatik.rwth-aachen.de/pub/packages/ButtonFaceLib/ and also at
ftp://ftp.x.org/contrib/widgets/motif/ButtonFaceLib/ [4/96].
