Event
class is obsolete and is
available only for backwards compatibility. It has been replaced
by the AWTEvent
class and its subclasses.
Event
is a platform-independent class that
encapsulates events from the platform's Graphical User
Interface in the Java 1.0 event model. In Java 1.1
and later versions, the Event
class is maintained
only for backwards compatibility. The information in this
class description is provided to assist programmers in
converting Java 1.0 programs to the new event model.
In the Java 1.0 event model, an event contains an
id
field
that indicates what type of event it is and which other
Event
variables are relevant for the event.
For keyboard events, key
contains a value indicating which key was activated, and
modifiers
contains the
modifiers for that event. For the KEY_PRESS and KEY_RELEASE
event ids, the value of key
is the unicode
character code for the key. For KEY_ACTION and
KEY_ACTION_RELEASE, the value of key
is
one of the defined action-key identifiers in the
Event
class (PGUP
,
PGDN
, F1
, F2
, etc).
