Class TextEvent


public class TextEvent extends Object
This event is sent to implementers of 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.

An empty text event usually indicates a change of the viewer's redraw state.

Clients other than text viewer's don't create instances of this class.
