+/**
+ * This event is sent to implementers of
+ * {@link dwtx.jface.text.ITextListener}. It represents a change applied
+ * to text viewer. The change is specified as a replace command using offset,
+ * length, inserted text, and replaced text. The text viewer issues a text event
+ * after the viewer has been changed either in response to a change of the
+ * viewer's document or when the viewer's visual content has been changed. In
+ * the first case, the text event also carries the original document event.
+ * Depending on the viewer's presentation mode, the text event coordinates are
+ * different from the document event's coordinates.
+ * <p>
+ * An empty text event usually indicates a change of the viewer's redraw state.</p>
+ * <p>
+ * Clients other than text viewer's don't create instances of this class.</p>
