// Life3DConfig.java// Andrew Davison, July 2006, ad@fivedots.coe.psu.ac.th/* A set of controls for modifying the 7 properties managed by   the LifeProperties object, lifeProps:     * fullscreen: whether the Life3D appl is full-screen     * width, height: the dimensions of the window if not full-screen     * bgColour: the background colour used in Life3D;                 it may be blue, green, white, or black     * speed: the speed that the balls grid rotates;              it may be slow, medium, or fast     * the birth and die ranges used by the Life rules in CellsGrid.        A range is a series of numbers separated by spaces, each        number representing the number of neighbours that will trigger       the cell's birth/death.    The GUI uses:      * a group of RadioButtons for the speed values      * a combo box for the background colours      * a group of two radio buttons for fullscreen and window      * two textfields for the window's width and height      * two textfields for the birth and die ranges*/import javax.swing.*;import javax.swing.border.*;import java.awt.*;import java.awt.event.*;import java.util.*;import java.io.*;public class Life3DConfig extends JPanel						         implements ActionListener{  // the GUI elements  private JRadioButton slowButton, mediumButton, fastButton;
