Interface IAnnotationHover

  • All Known Implementing Classes:
    DefaultAnnotationHover, LineChangeHover

    public interface IAnnotationHover
    Provides the information to be displayed in a hover popup window which appears over the presentation area of annotations.

    In order to provide backward compatibility for clients of IAnnotationHover, extension interfaces are used as a means of evolution. The following extension interfaces exist:

    • IAnnotationHoverExtension since version 3.0 allowing a text hover to provide a creator for the hover control. This allows for sophisticated hovers in a way that information computed by the hover can be displayed in the best possible form.
    • IAnnotationHoverExtension2 since version 3.2 allowing a text hover to specify whether it handles mouse-wheel events itself.

    Clients may implement this interface.
