The GdomeEvent interface is used to provide contextual information about an
event to the handler processing the event. An object which implements the
GdomeEvent interface is generally passed as the first parameter to an event
handler. More specific context information is passed to event handlers by
deriving additional interfaces from GdomeEvent which contain information
directly relating to the type of event they accompany. These derived interfaces
are also implemented by the object passed to the event listener.
the time (in milliseconds relative to the epoch) at which the
event was created. Due to the fact that some systems may not provide this
information the value of timeStamp may be not available for all events.
When not available, a value of 0 will be returned. Examples of epoch time
are the time of the system start or 0:0:0 UTC 1st January 1970.
The initEvent method is used to initialize the value of an Event created
through the gdome_doc_createEvent() API. This method may only be called
before the Event has been dispatched via the dispatchEvent method, though
it may be called multiple times during that phase if necessary. If called
multiple times the final invocation takes precedence. If called from a
subclass of Event interface only the values specified in the initEvent
method are modified, all other attributes are left unchanged.
Event Object ref
Specifies the event type. This type may be any event type
currently defined in this specification or a new event type.
The string must be an XML name.
Any new event type must not begin with any upper, lower, or
mixed case version of the string "DOM".
This prefix is reserved for future DOM event sets. It is
also strongly recommended that third parties adding their
own events use their own prefix to avoid confusion and
lessen the probability of conflicts with other new events.
Specifies whether or not the event can bubble.
Specifies whether or not the event's default action can be
If an event is cancelable, the preventDefault method is used to signify
that the event is to be canceled, meaning any default action normally
taken by the implementation as a result of the event will not occur. If,
during any stage of event flow, the preventDefault method is called the
event is canceled. Any default action associated with the event will not
occur. Calling this method for a non-cancelable event has no effect. Once
preventDefault has been called it will remain in effect throughout the
remainder of the event's propagation. This method may be used during any
stage of event flow.
The stopPropagation method is used prevent further propagation of an event
during event flow. If this method is called by any EventListener the event
will cease propagating through the tree. The event will complete dispatch
to all listeners on the current EventTarget before event flow stops. This
method may be used during any stage of event flow.
