| 31 | * <b>NOTE:</b> The <code>Event</code> class is obsolete and is | ||
| 32 | * available only for backwards compatilibility. It has been replaced | ||
| 33 | * by the <code>AWTEvent</code> class and its subclasses. | ||
| 34 | * <p> | ||
| 35 | * <code>Event</code> is a platform-independent class that | ||
| 36 | * encapsulates events from the platform's Graphical User | ||
| 37 | * Interface in the Java 1.0 event model. In Java 1.1 | ||
| 38 | * and later versions, the <code>Event</code> class is maintained | ||
| 39 | * only for backwards compatibilty. The information in this | ||
| 40 | * class description is provided to assist programmers in | ||
| 41 | * converting Java 1.0 programs to the new event model. | ||
| 42 | * <p> | ||
| 43 | * In the Java 1.0 event model, an event contains an | ||
| 44 | * {@link Event#id} field | ||
| 45 | * that indicates what type of event it is and which other | ||
| 46 | * <code>Event</code> variables are relevant for the event. | ||
| 47 | * <p> | ||
| 48 | * For keyboard events, {@link Event#key} | ||
| 49 | * contains a value indicating which key was activated, and | ||
| 50 | * {@link Event#modifiers} contains the | ||
| 51 | * modifiers for that event. For the KEY_PRESS and KEY_RELEASE | ||
| 52 | * event ids, the value of <code>key</code> is the unicode | ||
| 53 | * character code for the key. For KEY_ACTION and | ||
| 54 | * KEY_ACTION_RELEASE, the value of <code>key</code> is | ||
| 55 | * one of the defined action-key identifiers in the | ||
| 56 | * <code>Event</code> class (<code>PGUP</code>, | ||
| 57 | * <code>PGDN</code>, <code>F1</code>, <code>F2</code>, etc). | ||
