| * <b>NOTE:</b> The {@code Event} class is obsolete and is |
| * available only for backwards compatibility. It has been replaced |
| * by the {@code AWTEvent} class and its subclasses. |
| * <p> |
| * {@code 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 {@code 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. |
| * <p> |
| * In the Java 1.0 event model, an event contains an |
| * {@link Event#id} field |
| * that indicates what type of event it is and which other |
| * {@code Event} variables are relevant for the event. |
| * <p> |
| * For keyboard events, {@link Event#key} |
| * contains a value indicating which key was activated, and |
| * {@link Event#modifiers} contains the |
| * modifiers for that event. For the KEY_PRESS and KEY_RELEASE |
| * event ids, the value of {@code key} is the unicode |
| * character code for the key. For KEY_ACTION and |
| * KEY_ACTION_RELEASE, the value of {@code key} is |
| * one of the defined action-key identifiers in the |
| * {@code Event} class ({@code PGUP}, |
| * {@code PGDN}, {@code F1}, {@code F2}, etc). |
| * |
| * @deprecated It is recommended that {@code AWTEvent} and its subclasses be |
| * used instead |
