Examples of IVerticalRulerInfo

org.eclipse.jface.text.source.IVerticalRulerInfo
A vertical ruler is a visual component which may serve text viewers as an annotation presentation area. The vertical ruler info provides interested clients with the mapping and interaction aspect of the vertical ruler. This covers the mapping between coordinates of the ruler's control and line numbers based on the connected text viewer's document. In order to provide backward compatibility for clients of IVerticalRulerInfo, extension interfaces are used as a means of evolution. The following extension interfaces exist:
- {@link org.eclipse.jface.text.source.IVerticalRulerInfoExtension} sinceversion 3.0 allowing custom annotation hovers and specific annotation models.
@see org.eclipse.jface.text.source.IVerticalRulerInfoExtension @since 2.0
