Constructs a new instance of this class given its parent
and a style value describing its behavior and appearance.
<p>
The style value is either one of the style constants defined in
class <code>SWT</code> which is applicable to instances of this
class, or must be built by <em>bitwise OR</em>'ing together
(that is, using the <code>int</code> "|" operator) two or more
of those <code>SWT</code> style constants. The class description
lists the style constants that are applicable to the class.
Style bits are also inherited from superclasses.
@param parent a shell which will be the parent of the new instance
