The rxlistreq executable in this archive was coded
in pure Amiga JForth 3.1 over a couple of hot summer
evenings. Version 2.0 was revised one cool autumn afternoon
and subsequently bug-fixed to version 2.3 for the
present release.

This archive has an AREXX host and sample arexx script
for an example of how to use AREXX and the supplied host
program to allow your AREXX scripts to open a listview with
a list of items of any size that you define. The user may
click on an item to indicate a choice, or click on a CANCEL
button or the window's close button, or hit HELP or the ESC
key. All user input is returned to the calling program when
the window is closed.

This program uses native GadTools gadgets, and at the moment
there is no support for multiple selection or editing of
items in the listview gadget. The program provides a simple
but attractive window that is resizable as well as customizable
from the rexx script for size, position, and label names. It
uses the screen font by default. You can open it on your own
public screens too.

You may have the listview display a sorted list. In version 2.0
only an ascending order may be specified using the RXLV.SORTED = 'YES'
variable as a flag.

Complete documentation is provided by the included rxlistreq.readme
and is also included in the lvtest.rexx program.

See the history file (new in version 2.1) to see additional notes.

Run the lvtest.rexx script by typing 'rx lvtest'. rxlistreq needs to
be in the same directory as the arexx script lvtest.rexx unless you
edit the script to define the full path to the host executable rxlistreq.

Enjoy!
