public class DCCApplet
extends BaseApplet2

Applet to display Depletion, Current and Capacitance.

A DepletionWidth object is used to show depletion at a given voltage, which may be selected using the voltage sliders (both graphs have a voltage slider; these are connected and equivalent).

Method Summary
 void actionPerformed(java.awt.event.ActionEvent ae)
          Subclasses should at least provide an empty implementation of this method.
 void doPaint(java.awt.Graphics g)
          Called by forcePaint() to actually perform the painting.

Constructor Detail

DCCApplet

public DCCApplet()
Method Detail

init

public void init()
Description copied from class: BaseApplet2
Performs extra initialisation, including adding a panel to the bottom of the applet.
Overrides:
init in class BaseApplet2

doPaint

public void doPaint(java.awt.Graphics g)
Description copied from class: BaseApplet
Called by forcePaint() to actually perform the painting. Subclasses should implement this method as if it were the standard paint() method; buffering will then take place transparently.
Overrides:
doPaint in class BaseApplet
Tags copied from class: BaseApplet
Parameters:
g - The Graphics object on which to paint

updateInput

public void updateInput()
Reads in (and validates) input from the text fields.
Throws:
java.lang.IllegalArgumentException - if any input fields are invalid

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent ae)
Description copied from class: BaseApplet
Subclasses should at least provide an empty implementation of this method.
Overrides:
actionPerformed in class BaseApplet

start

public void start()
Description copied from class: BaseApplet
Applets should use this method to perform any final initialisation necessary to "activate" the applet
Overrides:
start in class BaseApplet2

stop

public void stop()
Description copied from class: BaseApplet
When this method is called, the applet should cease any user interaction. In particular, any threads explicitly started should be stopped, any external resources should be closed. This method should negate the action of start().
Overrides:
stop in class BaseApplet2
