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()

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

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
