Class zwt.ui.container.ContentEventManager

Extends zwt.event.EventManager.

A part controller event manager is used by a part controller to process part controller events and dispatch them to the appropriate handlers.

Handlers are methods previously registered on the event manager to handle a specific type of event. A typical handler method has two input parameters: the object that triggered the event and the event. An optional object argument may also be passed to the handler if it was provided when dispatching the event to the event manager (see zwt.event.EventManager#onEvent).

Defined in: ContentEventManager.js.
