There are now movies up of Moztop in action. While I'm generally not a big fan of cross platform GUI toolkits, including Mozilla's, it's better that it runs on multiple platforms poorly than on the ones I can't get to, I suppose.
Stephan is doing most of the work, so all I have to do is the final preparation for a 0.1 release. What is Moztop? A site development environment for Zope 3. That's not enough explanation? Well, you'll just have to wait... [Zope Dispatches]
It's interesting to see this project resurrected. It was tried for Zope 2, but I imagine that not only was Mozilla still too young to support it, but that it was just a tough fit to put onto Zope 2. With Zope 3's component architecture and the ability to create full fledged View Components, which in many cases play the roll of view-controller (usually some sort of page template is the view, and the View Class, if one is written, is the controller. It updates the core content object and can do other framework level things such as event notification that the content object shouldn't care about), the work must be much easier. Hopefully the ability to dynamically generate forms based off of schema will include being able to generate XUL widgets as well as HTML, making it easy for component authors or configurators to add MozTop views without having to write too much XUL themselves.
