public abstract class Piface
extends java.awt.Frame
implements java.awt.event.ActionListener, java.awt.event.WindowListener, Closeable

Abstract class for simple construction a graphical interface. Subclasses need the following methods: 

      public void gui()       // to construct components
      public void click()     // default event handler
      public void var_changed  // event handler for var
For convenience, several component-adding methods are provided for use in gui(). These methods include slider(), bar(), interval(), checkbox(), and choice() -- each in several versions. The methods add listeners for the components and arrange them in column(s) in the order that they are called. To start a new column, call newColumn(). The current column is a PiPanel named "panel", which may be manipulated directly in gui() as needed. The interface works like this: Whenever a variable var is changed by user action, the value of that variable is set accordingly in this object. If a method named var_changed exists, it is called; otherwise, click() is called as the default event handler. Finally, all graphical components are updated to reflect the new values of all the variables. A large collection of mathematical functions are provided in this class, so that subclasses need not prefix them (e.g., we may call "log" rather than "Math.log".)

the value for xName such that yName's value is equal to target. The starting values used by the numerical method are xStart and xStart + xIncr. This places no restrictions on the solution.

                   int value)
Choices (drop-down lists) Note that these come in 2 varieties. When the items[] argument is String[], the associated variable is an integer equal to the index (0-based) of the selected item. When items[] is double[], the associated variable is a double equal to the selected value (provide the index of the desired starting value). If the code attempts to set a double choice variable, the closest one in items[] is used.

public void choice(java.lang.String name,

                  int value,
                  int columns)
Radio buttons - value is index (0-based) of selected button Usually you'll want hradio() or vradio() for horizontal or vertical arrangements; but you may use radio() to specify something in between. An empty string ("") makes a blank position in the grid; for example, if items[] = {"","choice 1","choice 2"} and columns = 2, the buttons will be arranged in a row below the label. SKIP all blank entries when figuring the index of a button; in the above example, "choice 1" corresponds to value 0.
