Just a question.

At the moment for my terminal emulator I tear down and recreate all
the field widgets each time the screen refreshes (a mixture of WText
and WLineEdit).

So the user updates the screen and presses enter. The updates are sent
to the mainframe which updates the mainframe screen. This is read and
the Wt "screen" cleared - deleting all the widgets - and then new
Widgets are created and these then are rendered for the user by Witty
(not sure this longer explanation is clearer!)

It works great.

But I always envisaged optimising this so that if the "layout" of the
screen is unchanged then only the text of changed fields would be
updated and the widgets reused. So I need to develop some logic for
this. The question I have is this - would Witty take advantage of this
optimisation in the way that the AJAX and the communication between
the browser and server works?

Also IE seems to have some problems setting the focus to the right
field (sometimes) - so I am hoping this might work better for IE -
less confusing for the brain damaged blighter!
