Interface ITextListener
-
All Known Implementing Classes:
-
HyperlinkManager,
PaintManager
-
public interface ITextListener
Text listeners registered with a text viewer are informed about all
modifications of an
ITextViewer by means of
text events. A text event describes a change as a replace operation.
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.
If a text listener receives a text event, it is guaranteed that both the
document and the viewer's visual representation are synchronized.
Clients may implement this interface.
