xtpanel - build an interactive program, from the command line
	  or using a simple scripting language

xtpanel provides a quick and easy way of producing a panel
containing interactive objects such as buttons, sliders, and text
fields, either from the command line or from an xtpanel script file.
Each panel object maintains a string representation of its value. When
the object is modified it updates its value and it can also perform an
action such as printing its value or calling a system command. Objects
can make use of the values of other objects in constructing their
actions, and they can set the values of other objects as the result of
an action. The result is an interactive X windows program, without the
need for conventional programming.

This program is not intended as a replacement for a full featured
interface programming toolkit like Tk or Dirt or as a replacement for a 
simple menu builder like xmenu, it falls somewhere in the gap between the two.
It is intended as an easy to use tool that can be used to add an
interactive wrapper to all those old programs and shells that you have 
lying around. 


Three utilities are provided with xtpanel. All three utilities are
written as xtpanel scripts. 

The first is a script generator. This is a collection af xtpanel scripts 
that can be used to build, examine and test xtpanel script files. 
It is invoked using the command "xtpanel-generator". The second utility is a
collection of example scripts and a master script that can be use to
view and run the examples. It is invoked using the command
"xtpanel-examples".  A particularly powerful demo is the "lister"
script example, which is a tool for maneuvering through a Unix
filesystem and viewing files at any level. The third is a set of
xtpanel scripts that present information about xtpanel, mostly taken
from this manual page, in an interactive, menu-driven form. This
is invoked by doing "xtpanel -help".

This program uses the X toolkit and the MIT Athena widget
set.
