/**
* Constructs a new instance of this class given the display to create it on 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.
*
* <p>Note: Currently, null can be passed in for the display argument. This has the effect of
* creating the tracker on the currently active display if there is one. If there is no current
* display, the tracker is created on a "default" display. <b>Passing in null as the display
* argument is not considered to be good coding style, and may not be supported in a future
* release of SWT.</b>
*
* @param display the display to create the tracker on
* @param style the style of control to construct
* @exception SWTException
* <ul>
* <li>ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent
* <li>ERROR_INVALID_SUBCLASS - if this class is not an allowed subclass
