public Calculator(org.eclipse.swt.widgets.Composite parent, int style)
The style value is either one of the style constants defined in class
SWT
which is applicable to instances of this class, or must be
built by bitwise OR'ing together (that is, using the
int
"|" operator) two or more of those SWT
style
constants. The class description lists the style constants that are
applicable to the class. Style bits are also inherited from superclasses.
