| * Text listeners registered with a text viewer are informed about all |

| * <p> |
| * The changes described in the event are the changes applied to the text |
| * viewer's widget (i.e., its visual representation) and not those applied to the |
| * text viewer's document. The text event can be asked to return the |
| * corresponding document event. If the text event does not contain a document |
| * event, the modification of the text viewer is a presentation change. For |
| * example, changing the visible region of a text viewer, is a presentation |
| * change. A completely empty text event represents a change of the viewer's |
| * redraw state. |
| * <p> |
| * If a text listener receives a text event, it is guaranteed that both the |
