The DocumentEvent interface provides a mechanism by which the
user can create an Event of a type supported by the implementation. It is
expected that the DocumentEvent interface will be
implemented on the same object which implements the Document
interface in an implementation which supports the Event model.
eventType The eventType parameter specifies the
type of Event interface to be created. If the
Event interface specified is supported by the
implementation this method will return a new Event of
the interface type requested. If the Event is to be
dispatched via the dispatchEvent method the
appropriate event init method must be called after creation in
order to initialize the Event's values. As an example,
a user wishing to synthesize some kind of UIEvent
would call createEvent with the parameter "UIEvents".
The initUIEvent method could then be called on the
newly created UIEvent to set the specific type of
UIEvent to be dispatched and set its context information.The
createEvent method is used in creating
Events when it is either inconvenient or unnecessary
for the user to create an Event themselves. In cases
where the implementation provided Event is
insufficient, users may supply their own Event
implementations for use with the dispatchEvent method.
