public class PaLoader
extends java.applet.Applet

Tutorial on geometry loaders. This tutorial explains how to write and use an own geometry loader within JavaView.

The loader used in the init() method of this applet can be replaced with any of the built-in loaders (jv.loader.*, jvx.loader.*) of JavaView.

PaLoader

public PaLoader()

Method Detail

getAppletInfo

public java.lang.String getAppletInfo()

Interface of applet to inform about author, version, and copyright.

Overrides:

getAppletInfo in class java.applet.Applet

init

public void init()

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

p Note, for tutorial reasons this method still continues even if parsing errors appear.

Overrides:

init in class java.applet.Applet

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.

Overrides:

paint in class java.awt.Container

destroy

public void destroy()

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

Overrides:

destroy in class java.applet.Applet

start

public void start()

Start viewer, e.g. start animation if requested

Overrides:

start in class java.applet.Applet

stop

public void stop()

Stop viewer, e.g. stop animation if requested

Overrides:

stop in class java.applet.Applet
