All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.image.ImageObserver, java.awt.MenuContainer, java.lang.Runnable, java.io.Serializable

public class PaSurface

extends java.applet.Applet

implements java.lang.Runnable

Applet loads classic parametrized surfaces.

Version:

19.07.99, 1.10 revised (kp) Use a seperate thread to do initialization.
24.11.98, 1.01 revised (kp) Main() method modified and a call of pack()
inserted since frame with empty viewer randomly appeared at startup.
06.10.98, 1.00 created (kp)

PaSurface

public PaSurface()

Method Detail

getParameterInfo

public java.lang.String[][] getParameterInfo()

Interface used by design tools to show properties of applet. This method returns a list of string arrays, each of length 4 rather than 3 as suggest by Java. The additional string at third position contains the value of the parameter.

Overrides:

getParameterInfo in class java.applet.Applet

See Also:

PvViewer.getParameter(String)

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()

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

Overrides:

init in class java.applet.Applet

run

public void run()

Configure and initialize the viewer, load system and user projects. The user projects must be selected here in a semicolon separated list. Applet parameters "SurfaceName", "SurfaceParams" and "SurfaceColors" can be defined. SurfaceName: Users projects to load with names "PgSurface_"+SurfaceName SurfaceParams: Uppercase means show, lowercase means don't show, not defined means standard, i.e. vLEb v: vertices l: edges (lines) e: elements b: boundary SurfaceColors: w: white r: red g: green b: blue c: cyan m: magenta y: yellow k: black

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.

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

stop

public void stop()

Stop viewer, e.g. stop animation if requested

Overrides:

stop in class java.applet.Applet

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.
