Hi John.
We could do that. I'm sort of leaving it to Brandon and Chuck but what I had in
mind is to just have methods in each view like:
onInitialUpdate
and
onUpdate
Each view is bound to the document and so in these two methods they would just
make whatever calls to the document they needed to initialize and update
themselves.
Since we have several different kinds of views we might also want to define an
interface that each view can implement to handle communication with the
document.
This is much cleaner I think than having something that has to know about each
view and initialize it.

Subject: [brailleblaster] Proposal: a new class in views package
I think it would be a good idea to have a class in the views package called
something like innitializeViews . It would call on methods in DocumentBase to
provide the text and Braille associated with elements and would call another
method to transmit back the starting and ending positions of the text in the
StyledText view. This information would later be used to find the location in
the document corresponding to the cursor location. It would be updated when the
document is edited.
