Interface IWidgetTokenOwner

  • All Known Implementing Classes:
    ProjectionViewer, SourceViewer, TextConsoleViewer, TextViewer

    public interface IWidgetTokenOwner
    In order to display information in a temporary window, a widget token must be acquired. The intent behind this concept is that only one temporary window should be presented at any moment in time and also to avoid overlapping temporary windows. This concept is used by the ITextViewer.

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

    • IWidgetTokenOwnerExtension since version 3.0 introducing priorities when requesting a widget token and thus replacing the non-prioritized scheme.
    Since:
    2.0
