org.eclipse.jface.text.ITextViewerExtension
Extension interface for {@link org.eclipse.jface.text.ITextViewer}.
This extension interface replaces the event consumer mechanism ( {@link org.eclipse.jface.text.ITextViewer#setEventConsumer(IEventConsumer)}) with a set of methods that allow to manage a sequence of {@link org.eclipse.swt.custom.VerifyKeyListener}objects. It also adds
- access to the control of this viewer
- marked region support as in emacs
- control of the viewer's redraw behavior by introducing setRedraw(boolean)
- access to the viewer's rewrite target.
A rewrite target ( {@link org.eclipse.jface.text.IRewriteTarget}) represents an facade offering the necessary methods to manipulate a document that is the input document of a text viewer. @since 2.0
