@Deprecated(since="9") public class Event extends Object implements Serializable
Deprecated.It is recommended thatAWTEventand its subclasses be used insteadNOTE: TheEventclass is obsolete and is available only for backwards compatibility. It has been replaced by theAWTEventclass and its subclasses.Eventis a platform-independent class that encapsulates events from the platform's Graphical User Interface in the Java 1.0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, theEventclass 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
idfield that indicates what type of event it is and which otherEventvariables are relevant for the event.For keyboard events,
keycontains a value indicating which key was activated, andmodifierscontains the modifiers for that event. For the KEY_PRESS and KEY_RELEASE event ids, the value ofkeyis the unicode character code for the key. For KEY_ACTION and KEY_ACTION_RELEASE, the value ofkeyis one of the defined action-key identifiers in theEventclass (PGUP,PGDN,F1,F2, etc).- Since:
