Constructor Detail

PaLSystem

public PaLSystem()

Method Detail

init

public void init()

Create thread that configures and initializes the viewer, loads system and user projects.

run

public void run()

Configure and initialize the viewer, load system and user projects. One of the user projects may be selected here.

Specified by:

run in interface java.lang.Runnable

main

public static void main(java.lang.String[] args)

Standalone application support. The main() method acts as the applet's entry point when it is run as a standalone application. It is ignored if the applet is run from within an HTML page.

paint

public void paint(java.awt.Graphics g)

Print info while initializing applet and viewer.

destroy

public void destroy()

Does clean-up when applet is destroyed by the browser. Here we just close and dispose all our control windows.

stop

public void stop()

Stop viewer, e.g. stop animation if requested

startFromThread

public void startFromThread()

Start viewer, e.g. start animation if requested. Necessary, if initialization is done in a separate thread. In this case the original applet.start() has no effect.
