Adds a bidirectional segment listener.
<p>
A BidiSegmentEvent is sent
whenever a line of text is measured or rendered. The user can
specify text ranges in the line that should be treated as if they
had a different direction than the surrounding text.
This may be used when adjacent segments of right-to-left text should
not be reordered relative to each other.
E.g., Multiple Java string literals in a right-to-left language
should generally remain in logical order to each other, that is, the
way they are stored.

@param listener the listener
@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>
</ul>

<li>ERROR_NULL_ARGUMENT when listener is null</li>
