GLG JAVA DEMOS

The GlgDemoArchive.zip file is a jar archive that contains an image of
the web site to run the Glg Java demos from a local filesystem without
an access to a network.

The Glg Java Demos may be run either in a web browser, or as
stand-alone java programs.

DOWNLOADING AND EXTRACTING THE DEMO FILES

To run the demos, download the GlgDemoArchive.zip file and extract
the files using the jar utility:

	jar xvf GlgDemoArchive.zip

This will extract the following files:

   java_demos          - the top-level demo directory

      index.html       - the starting point for running the demos in a browser
      demos_java1.html - the starting point for running Java1 demos
      demos_java2.html - the starting point for running Java2 demos
      *.gif            - gif files used by index.html
      java.html        - description of the Glg Toolkit for Java

      java1            - Java1 demo directory
         *.html           - demo html files 
         *.java           - Java1 source code files for the demos
         *.glg and *.g    - GLG drawing files
         GlgEval.jar      - Glg class library for Java1
         GlgDemo.jar      - demo class files for Java1

      java2            - Java2 demo directory
         *.html           - demo html files 
         *.java           - Java2 source code files for the demos
         *.glg and *.g    - GLG drawing files
         GlgEval2.jar     - Glg class library for Java2
         GlgDemo2.jar     - demo class files for Java2

RUNNING THE GLG JAVA DEMOS IN A JAVA1-ENABLED BROWSER

Start your Web browser, load the java_demos/index.html file, select Java1 
and click on the Java demo you want to run.

RUNNING THE GLG JAVA DEMOS IN A JAVA2-ENABLED BROWSER

You need a Java2-enabled browser to run Java2 and Swing demos. If you
use Netscape or IE browsers, you'll need to install Sun's Java2
plug-in to enable Java2 in the browser.

To run the demos, start your Web browser and load the
java_demos/index.html file. Slect Java2, then click on the
Java demo you want to run.

RUNNING THE GLG JAVA DEMOS AS STAND-ALONE JAVA PROGRAMS

You can run the demos by either browsing the demos in a web browser
(starting with index.html), or starting the demos as stand-alone Java
programs.

To run the Java1 version of the demos as standalone java programs,
change to the "java_demos/java1" directory and set the CLASSPATH
environment variable to include the GlgEval.jar and GlgDemo.jar files:

	".:./GlgEval.jar:./GlgDemo.jar"

on UNIX, or:

	".;.\GlgEval.jar;.\GlgDemo.jar"

on Windows. 

To run the Java2 version of the demos, change to the "java_demos/java2"
directory and set the CLASSPATH to include the Java2 jar files:

	".:./GlgEval2.jar:./GlgDemo2.jar"

on UNIX, or:

	".;.\GlgEval2.jar;.\GlgDemo2.jar"

on Windows. 

Then start the demo of your choice by using one the following
commands:

	java GlgAircombatDemo      (Aircombat simulation)
	java GlgMapDemo            (GIS visualization)
	java GlgProcessDemo	   (Process control demo)
	java GlgRobotArmDemo	   (3D simulation demo)
	java GlgAnimationDemo      (Simple game animation)
	java GlgAvionicsDemo       (Custom avionics gauges)
	java GlgGraphDemo	   (Glg graph samples)
	java GlgGraphCrossWireDemo (Custom graph with a cross-hair cursor)
	java GlgGraphLayoutDemo	   (Graph layout example)
	java GlgNetworkDemo	   (Network monitoring demo)

To run the Graph Layout Demo, the GlgGraphLayout.jar must also be
added to the CLASSPATH.

On both Windows and Unix, you can use JRE to run the demos:

Java1/AWT:
	jre -cp .;.\GlgEval.jar;.\GlgDemo.jar <demo_name>   (on Windows)

	jre -cp .:./GlgEval.jar:./GlgDemo.jar <demo_name>   (on Unix)

Java2/Swing:
	jre -cp .;.\GlgEval2.jar;.\GlgDemo2.jar <demo_name>   (on Windows)

	jre -cp .:./GlgEval2.jar:./GlgDemo2.jar <demo_name>   (on Unix)


To recompile the demo source code using the same class path, use the
following command:

	javac <demo_name>.java
