Examples of org.eclipse.jface.text.source.SourceViewer

org.eclipse.jface.text.source.SourceViewer
SWT based implementation of {@link org.eclipse.jface.text.source.ISourceViewer} and its extensioninterfaces. The same rules apply as for {@link org.eclipse.jface.text.TextViewer}. A source viewer uses an IVerticalRuler as its annotation presentation area. The vertical ruler is a small strip shown left of the viewer's text widget. A source viewer uses an IOverviewRuler as its presentation area for the annotation overview. The overview ruler is a small strip shown right of the viewer's text widget.
Clients are supposed to instantiate a source viewer and subsequently to communicate with it exclusively using the ISourceViewer and its extension interfaces.

Clients may subclass this class but should expect some breakage by future releases.
