* <b>NOTE:</b> The <code>Event</code> class is obsolete and is |
|
| 21278 | 32 |
* available only for backwards compatibility. It has been replaced |
| 2 | 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 |
|
| 21278 | 39 |
* only for backwards compatibility. The information in this |
| 2 | 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). |
