/**
** IntegerExample.c -- Integer class Example.
**
** This is a simple example testing some of the capabilities of the
** Integer gadget class.
**
** This code opens a window and then creates 2 Integer gadgets which
** are subsequently attached to the window's gadget list. One uses
** arrows, one does not. Notice that you can tab cycle between them.
