I created this screencast to demonstrate how to work with Griffon MVC Groups and the event bus. Griffon has a strong MVC focus, and functionality is built using MVC groups. This is not a screen or a form, an MVC group is a piece of functionality, and a single form is made of MVC groups composed together. The way MVC groups talk to each other is through an event bus, rather than being coupled directly to each other.
If you want written documentation on these topics, then please read:

* The Griffon User Guide - http://dist.codehaus.org/griffon/guide/index.html
