| /** |
| * A semantic event which indicates that an object's text changed. |
| * This high-level event is generated by an object (such as a TextComponent) |
| * when its text changes. The event is passed to |
| * every {@code TextListener} object which registered to receive such |
| * events using the component's {@code addTextListener} method. |
| * <P> |
| * The object that implements the {@code TextListener} interface gets |
| * this {@code TextEvent} when the event occurs. The listener is |
| * spared the details of processing individual mouse movements and key strokes |
| * Instead, it can process a "meaningful" (semantic) event like "text changed". |
| * <p> |
| * An unspecified behavior will be caused if the {@code id} parameter |
| * of any particular {@code TextEvent} instance is not |
| * in the range from {@code TEXT_FIRST} to {@code TEXT_LAST}. |
