This page was not close to be complete. I think a more important piece of information is not how but when and whether to use event publishing/subscription as the communication mechanism between components and between components and core.
* the scenario when we probably should use event publishing/subscription:
** the subscribers are potentially to be multiple
** the subscribers are unknown to the publisher in advence
* the scenario when we probably should not user event publishing/subscription
** the subscriber is one known component. even more so when the subscriber is a class in the core, e.g. ProjectPanel.
** from the subscriber's pointer of view, be cautious if you want to do something slow when you receive the event, especially in synchronous mode.
