public class PaLoader
extends PvApplet

Tutorial on geometry loaders 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.

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.

Specified by:

getAppletInfo in class PvApplet

getSizeOfFrame

public java.awt.Rectangle getSizeOfFrame()

Return a new allocated project instance.

Overrides:

getSizeOfFrame in class PvApplet

getProject

public PjProject getProject()

/** Return a new allocated project instance.

Specified by:

getProject in class PvApplet

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.
