Event class is obsolete and is
available only for backwards compatilibility. It has been replaced
by the AWTEvent class and its subclasses.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 compatibilty. 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
Event#id field
that indicates what type of event it is and which other
Event variables are relevant for the event.
For keyboard events, Event#key
contains a value indicating which key was activated, and
Event#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).

Translates this event so that its x and y coordinates are increased by dx and dy, respectively. This method translates an event relative to the given component. This involves, at a minimum, translating the coordinates into the local coordinate system of the given component. It may also involve translating a region in the case of an expose event. |
