Constructs a new instance of this class given only the style
value describing its behavior and appearance. This is equivalent
to calling <code>Shell((Display) null, style)</code>.
<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 style the style of control to construct

<li>ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent</li>
<li>ERROR_INVALID_SUBCLASS - if this class is not an allowed subclass</li>
