Examples of jscicalc.button.CalculatorButton

• jscicalc.button.CalculatorButton
  Each button on the calculator is an instance of this class. Each button contains two important pieces of information. It knows about a PObject object. This object usually contains the information necessary for some calculator function such as plus, log or even a Numeral that needs to be stored in an expression. There are a few exceptions, such as the Mode and Shift buttons, where information needs to be sent to the CalculatorApplet object, but does not form part of an expression that the Parser object will evaluate. Generally, buttons that do more than create part of an expression use a subclass of this. The second piece of information that an object of this class needs is the CalculatorApplet object. Buttons don’t deal directly with the Parser object but rather request that the CalculatorApplet object do this for them. Buttons are made available to the user through CalculatorPanel and its subclasses. @see CalculatorApplet @see PObject @see Parser @see CalculatorPanel @author J. D. Lamb @version $Revision: 1.7 $
