I think we just need a good name. I agree that "predict" isn't the
API we want.<br>
<br>
How about "requestFocusTraversal"? It has symmetry with
requestFocus.<br>

Traversal API</span><span style="font-size:12.0pt"><o:p></o:p></span></p>
</div>
<div>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:11.0pt">Maybe we
can polish the naming a bit:<br>
<br>
When used as a transitive verb,
"traverse" means (according to<br>
Merriam-Webster): to go or travel
across or over, to move or pass<br>
along or through.<br>
<br>
MW gives the example: "light rays
traversing a crystal". So one thing<br>
is moving (light rays), while the
other thing is static (a crystal).<br>
Cambridge gives the example "Stanley
traversed the continent from west<br>
to east." Again, "Stanley" is
moving, "the continent" is static.<br>
<br>
Since "traverseFocus" is a
transitive verb followed by a direct
noun,<br>
it sounds to me like "focus" is the
thing that can be traversed over<br>
or across.<br>
As an analogy, let's call the method
"traverseContinent" for a moment.<br>
It becomes obvious that "continent"
is the space which is traveled<br>
across, and not the thing
travelling.<br>
<br>
In our case, "focus" is the moving
thing, not the thing that it is<br>
moved across. I would use something
like "moveFocus", "shiftFocus", or<br>
something along those lines.<br>
<br>
As for "TraversalDirection", I think
it is acceptable, but I'll note<br>
that to me, "direction" implies one
of the four directional modes, not<br>
the two logical modes (previous and
next).</span><span style="font-size:12.0pt"><o:p></o:p></span></p>
