Calculator

Introduction

A simple calculator, displayed as a whole widget or inside a combo.

Usage

This is very simple : you instantiate a Calculator or a CalculatorCombo, then you attach a ModifyListener in order to be informed when the value changed :

final Calculator calc = new Calculator(shell, SWT.NONE);
calc.addModifyListener(new ModifyListener() {

 @Override
 public void modifyText(final ModifyEvent e) {
          System.out.println("New value is " + calc.getValue());
 }
});

And voilà !
