xforms - A GUI Toolkit for X Window Systems
Forms Library for X (xforms) is a GUI toolkit and builder for the X
Window Systems and runs on all major UNIX platforms as well as OpenVMS
and OS2. Forms Library is too complex to be described in the "man"
page format. Ask your system administrator for the location of the
HTML, PDF or PostScript document or follow the links on the Forms
Library’s home page for an online version of the documentation.
Forms Library is a graphical user interface toolkit based on Xlib for X
Window Systems. It comes with a rich set of objects such as buttons,
browsers, sliders and menus integrated into an elegant event/object
callback execution model that allows fast and easy construction of X
applications. In addition, the library has support for image read and
write, format conversion and simple image processing. The library
consists of a flexible set of C-routines that can be used in C and C++
programs (As of this writing, perl, ada95, pascal, scheme and Fortran
bindings to the Forms Library are in beta.)
The library is efficient and portable and runs on all major Unix
platforms, including Sun, SGI, HP, DEC Alpha/OSF, IBM RS6000, Convex,
Cray, Linux, FreeBSD, NetBSD, SCO, Unixware, OpenBSD , BSDi,
DecSystem(mips)/Ultrix and others. Non-unix platforms include OpenVMS,
OS/2, and Window/NT.
Bundled with the library is also a Form designer, fdesign, which can be
used to build interaction forms in a WYSIWYG (what you see is what you
get) way and to generate the corresponding C (or any of the binding
languages) code for you. 50+ demos in source code are distributed with
All programs written using the Forms Library recognize the following
command line options
specifies the server to connect to.
specifies the border width to use for built-in objects.
prints the xforms version information.
requests a visual by name such as TrueColor etc. By default the
Forms Library always selects the visual that has the most depth.
requests a specific depth.
generates some info about the state of the XForms. where level
is an integer between 1-5 and controls the amount of information
to output. Depending on the options used when the Forms Library
was built, a level more than 3 might not be available.
-sync runs the application in synchronous mode with debug level set to
requests a private colormap for the application.
requests a shared colormap even if the application needs more
colors than available. For those colors that can’t be allocated
in the shared colormap, substitutions are made so the closest
matching color is used.
requests a standard colormap.
specifies the application name under which resources are to be
obtained, rather than the default executable file name.
