----

Prerequisites:

This program runs under any OS,
(e.g. Win2K/XP/Vista/W7x86/W7-64/OSX/Linux/Solaris/AIX...) so long as you have
<><> Java version 1.5 <><> or later installed (32-bit or 64-bit Java).
See http://mindprod.com/jgloss/installingjava.html for details.

----

Installing on a PC:

Download source and compiled class files to run on your own machine as an application.
First install a recent Java JDK or JVM.
See http://mindprod.com/jgloss/installingjava.html.
To install, extract the zip download with WinZip
(or similar unzip utility) into any directory you please,
often J:\ --  ticking off the "use folder names" option.
To run as an application,type:
java -ea -jar J:\com\mindprod\spinner\spinner.jar {put any parms here}

adjusting as necessary to account for where the jar file is.

----

Installing on a MacIntosh:

Use Safari to download source and compiled class files to run on your own machine as an application.
Safari will automatically unpack the zip into ~/Downloads (version 10.5)
[or on the Desktop (version 10.4 and earlier)].
First install a recent Java JDK or JVM.
See http://mindprod.com/jgloss/installingjava.html.
You may optionally move the download tree to a permanent home.
I don't have a MacIntosh, just a PC, so I can't test my Java programs for Mac compatibility.
In theory they should work without problems, but in practice that does not always happen.
If you have problems please, let me know, preferably with screenshots and complete verbatim error messages.
To run as an application, without parameters, just double click the jar file.

To run as an application with parameters, in bash shell type:
open Terminal.app
cd ~/Desktop
java -ea -jar com/mindprod/spinner/spinner.jar {put any parms here}

adjusting as necessary to account for where the jar file is.

----

Rebuilding:

The zip already contains the necessary class and jar files, so unless you modify
the program, there is no need to recompile the source or rebuild the jar.
Configure.java basedir="E:/" in rebuild.xml to the drive where your files are.
Use ANT and rebuild.xml, not build.xml, to recompile and recreate the jar.

----

Use:

Spinner consists of source for a DateSpinner and classes to add hex and
formatted dollar input/output for Java JSpinner to your own Java programs.

The DateSpinner lets you enter dates by either keying yyyy-mm-dd or using a
three separate spinners for year, month and day.  It won't let you enter
an illegal date or one out of bounds.  If you spin a day too high, like an
odometer, it kicks over to the next month.  There is quite complex internal logic
that ensures the three spinners interact in intuitively expected ways.

Spinner offers two NumberFormatter classes you can use with a JSpinner.
One is HexNumberFormatter which lets your JSpinner range over hex values.
The other is DollarNumberFormatter which lets your JSpinner range over
dollar values.  It works better than JSpinner.NumberEditor with a
DecimalFormat String since DollarNumberFormatter displays the $ without
requiring it on input.  Further, DollarNumberFormatter automatically
rounds all values to the nearest penny.

The program does nothing on its own other that demonstrate the use of the
three classes.  The classes are designed to be used in your own programs.

You can see DateSpinners in production in the biorhythms calculator at
http://mindprod.com/applet/bio.html

Why the double arrow icon?  That's what the up/down control on a Java
JSpinner looks like.
