[Zope] HTML formatting from a text field

[sean.upton@uniontrib.com]

I remember reading somewhere about messaging between Java applets and
JavaScript code in the browser, allowing JavaScript code from a web form to
manipulate the applet output; the example was typing something into a text
box, clicking a button in a form, and having that rendered in some obscure
font inside the applet.  Where I read this escapes me, and I've never tried
this, but I wonder if such a trick works conversely.  In other words, what
if the applet can pass values to a JavaScript variable associated with the
value of a form input element in the browser's HTML DOM?

I could imagine that something like this could be very effective for certain
situations where people want better through-the-web editing of code (imagine
if you could edit dtml in a web form color coding syntax with a feature to
collapse blocks of code, similar to Homesite 4.5, or editing python scripts
-- what were python methods -- with an outline-based editor that created
automatic indentation).

Or, better yet, imagine running JPython within the applet (I don't know
whether this is possible) to do all this.  

Anyway, I wonder if this type of thing could be an alternative to either
ActiveX components or a XUL/XPCOM based-interface.

There was a start at a product doing this (called ZIE) by Johan Carlsson
, but it looks like it was aborted quite some time ago. Dont know about
its status. You could try how far it would get you, tho
