Returns an array of zero-relative integers that map
the creation order of the receiver's items to the
order in which they are currently being displayed.
<p>
Specifically, the indices of the returned array represent
the current visual order of the items, and the contents
of the array represent the creation order of the items.
</p><p>
Note: This is not the actual structure used by the receiver
to maintain its list of items, so modifying the array will
not affect the receiver.

@return the current visual order of the receiver's items
@exception SWTException <ul>
<li>ERROR_WIDGET_DISPOSED - if the receiver has been disposed</li>
<li>ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver</li>
