Xo
The Open Widget Set
Release 2.1

Introduction.
Xo is a widget set with functionality similar to that of Motif but
with a cleaner design. It interacts well with other widget sets
and, more importantly, it is easy for others to write widgets to extend
the base widget set. Documentation is quite extensive and
accurate. Walking (hierarchical) and pulldown menus are provided.
Keyboard traversals (using the keyboard instead of the mouse) and
hardcopy output (at least postscript) are planned. In particular,
all the header files are programmatically generated.
The latest version can be found in archive.cis.ohio-state.edu:pub/Xo/*
Contact wa...@cis.ohio-state.edu for more information.
Current widgets implemented are:
Box A manager widget that places widgets in a rectangular
arrangment with identical sizes.
Button A widget that allows the user to ``press'' a button to
cause something to happen.
Column Arranges children in a column
CompBase Provides common functionality for composite widgets.
ConsBase Provides common functionality for constraint widgets.
Grip A widget for allowing user to change widget dimensions
Label A widget that displays either text or a pixmap.
Menu A manager widget for holding the widgets in a menu.
MenuBar A manager widget for holding pulldown menus.
MenuBarButton For pulldown menus inside a MenuBar.
MenuButton A widget that is placed inside of a menu. Allows the
display of either text or a pixmap. Submenus can be
attached to a menubutton.
MenuShell An override shell that allows multiple children
(speeds up submenus signicantly).
Obj2dBorder Draws a simple line for border edge.
Obj3dborder Draws a beveled edge for a border.
ObjArrow An arrow that can point left, right, up or down.
ObjBorder Defines the basic behavior of borders.
ObjDraw Provides common function for gadgets.
ObjLabel A gadget that displays lines of text
ObjLabelFormat
A gadget that allows for embedded control strings to
signify formatting.
ObjPixmap A gadget that displays a pixmap (not yet implemented).
Row Arranges children in a row
Scrollbar Allows user to interactively change viewing area (incomplete).
Seperator A gadget that draws a chiseled edge. Typically used in a
\class{Label} widget to distuinguish between sections in
a menu (soon implemented, not yet).
Simple A widget that provided common functionality for many of
the widgets. Never directly used.
Vpane Arranges widgets in a column and allows the user to
interactively change the height.
Contents.
./X11 - For widget set include files
./X11/Xo - The Xo include files. MOST ARE AUTOMATICALLY GENERATED.
./build - A program that actually generates the Xo include
files and documentation
./doc - The LaTeX documentation for the system.
./examples - Various example programs
./examples/xfontsel - Port of the xfontsel program to this widget set
./libtable - A library that implements a generic insert/find/destroy
utility (currently only fixed size hashing).
./spec - The description of the widget set that ``build'' uses to
generate the include files and documentation
./src - The source for the Xo widgets
./test - Test programs
Portability.
This code is regularly compiled and run under:
______________________________________________________________________
Machine OS Compiler X11
______________________________________________________________________
Sun 3 SunOS 4.1 gcc -Wall R4,R5
Sun 4 SunOS 4.1 gcc -Wall R4,R5
Sun 4 SunOS 4.1 cc R4,R5

This code has compiled and run under:

Sun 4 Solarix 2.0 cc R5
SGI IRIX 4.0, IRIX 3.3 cc
E&S ESV2.0 cc -systype bsd43

Installation.
1. Examine ./Xo.tmpl. It has an option for compiling with
gcc. If you have TeX/LaTex installed, you may also want to
define HasTeX here so doc/Makefile gets generated correctly
2. "xmkmf" to generate ./Makefile
3. "make Makefiles" (to generate all the subdirectories' Makefiles)
4. "make"
5. "make depend" (if you like)
Note that the "build" program must exist so the include files
in X11/Xo can get generated from the specification in ./spec. This
also generated most of the LaTeX documents in ./doc.
Testing.
Only one test program exists in ./src/test.
A port of xfontsel to use pulldown menus is in ./examples/xfontsel.
This is currently broken.
