Examples of ITextViewerExtension5

org.eclipse.jface.text.ITextViewerExtension5
Extension interface for {@link org.eclipse.jface.text.ITextViewer}. Defines a conceptual replacement of the original visible region concept. This interface replaces {@link org.eclipse.jface.text.ITextViewerExtension3}.
Introduces the explicit concept of model and widget coordinates. For example, a selection returned by the text viewer's control is a widget selection. A widget selection always maps to a certain range of the viewer's document. This range is considered the model selection.
All model ranges that have a corresponding widget ranges are considered "exposed model ranges". The viewer can be requested to expose a given model range. Thus, a visible region is a particular degeneration of exposed model ranges.
This interface allows implementers to follow a sophisticated presentation model in which the visible presentation is a complex projection of the viewer's input document. @since 3.0
